Siemens Energy Sector • Power Engineering Guide • Edition 7.1 513 Services & Support 10.1 Asset Services 10.1.2 Substation Modernization Projects Because top priority is given to operational continuity in substations and power systems, any long-term maintenance, modernization and system rehabilitation must be precisely planned. These are the right opportunities for OEM(Original Equipment Manufacturer)-driven service projects. Siemens offers a variety of corresponding service solutions for extending the lifespan and size of the substation, or for its modernization. Countless examples worldwide serve as references for successfully executed service projects. 10 10.1.3 Monitoring and Diagnostics Gas density monitoring monitors the gas tightness with functions like inventory management, trending, and prediction of alarms. Gas density monitoring receives its signals from SF6 density transducers which operate with a 4 to 20mA current loop technology for high noise immunity. The result is a full SF6 inventory management system, capable of providing advance warning of SF6 leaks with highest accuracy. The very high accuracy measurement, combined with smart software functions, enables optimal and profitable gas density monitoring for high-voltage gas-insulated switchgear. Monitoring systems The condition of your assets is highly relevant to your decision making about service or replacement. With insight into the condition of the assets, the transition to Condition Based Maintenance (CBM) can take place. Minor failures can be repaired before they turn into a major problem and a breakdown occurs. Siemens offers both on-site one-time audits (see chapter 10.1.6 Audits and Consulting) and online condition monitoring as a stand-alone or integrated system. Partial discharge monitoring monitors the condition of the dielectric strength of the high-voltage gas-insulated switchgear. The product is based on more than 20 years experience of on-line UHF (ultra high frequency) partial discharge monitoring measurement, and includes OEM experience integrated into the product. Functions like automatic pattern recognition and the use of external noise detection complement the offer. A proper state of the dielectric strength is the key for safe and reliable operation of the GIS. With Integrated Substation Condition Monitoring (ISCM), Siemens provides online asset condition information through a comprehensive range of innovative tools for diagnostic analysis. Through prediction and prevention of equipment failures, ISCM products and services protect the customer’s company image as well as his investment. The integrated monitoring system guarantees minimum downtime, maximum asset performance, nearly real-time rating, and an extended lifespan. As a manufacturer of power transformers, Siemens integrated all engineering, manufacturing and maintenance knowledge into the transformer monitoring products. As a high-end solution, SITRAM CM is scalable up to most comprehensive monitoring functionalities with a high level of flexibility and customization. ISCM products and services are a fundamental prerequisite for securing the customer’s required performance level, and with it, long-term entrepreneurial success. The Siemens ISCM solution, customized to the individual requirements of the substation, monitors all relevant components of the power supply system – from transformers and switchgear to overhead lines and cables. It can be seamlessly integrated into the existing substation communication and visualization infrastructure, from simple bay controllers to high-end control center applications. Siemens offers one integral solution for all network assets. ISCM products and services provide a highly reliable solution, based on expert knowledge and advanced technology. With its unique proficiency and experience along the entire energy conversion chain, Siemens is ideally positioned to supply a sophisticated, comprehensive monitoring concept that covers all equipment within the power supply. ISCM products and services for high-voltage gas-insulated switchgear and transformers Siemens gas density monitoring (GDM) and Siemens partial discharge monitoring (PDM) ensure reliable and profitable monitoring of high-voltage gas-insulated switchgear. 514 Based on more than 20 years of experience, Ultra High Frequency (UHF) partial discharge monitoring and gas densitiy monitoring provide significant insight in the condition of highvoltage gas-insulated switchgear. Siemens Energy Sector • Power Engineering Guide • Edition 7.1 Siemens Transformer Condition Monitoring is a standardized product with high modularity. Transformer monitoring analyzes the important influences on transformer aging. The collected data received from fixed sensors cover the most essential measures to gain a clear indication of the transformer’s condition. All ISCM products are available as stand-alone products or can be integrated in a Substation Monitoring Project. Asset data management Substation Monitoring Projects integrate all monitored assets in one platform – the ISCM platform. A single screen pictures the condition of all assets, and operators can grasp at a glance if and for which asset preventive action is required. Starting with a complete substation view, a problem is indicated and assigned to the affected asset. The collected condition monitoring data is the basis for a profound diagnosis. Diagnosis can take place within intelligent sensors, or afterwards by evaluating the collected data. To get optimal results, Substation Monitoring Projects perform both. Services & Support 10.1 Asset Services The ISCM platform supports a fast, high-quality decision making process regarding further actions in case of alarm signals and warnings. Generated tendency indications help to decide whether an alarm needs immediate action or scheduled maintenance. Furthermore, guidance to fault locations and an adequate risk assessment is presented to the system user with explicit messages. Remote services Siemens provides remote supervision and expert support worldwide through Remote Diagnostic Centers. Siemens remote services comprise: • Hosting of your condition monitoring product or Substation Monitoring Project: Save on investments and operational cost for your own dedicated monitoring system, but have full functionality and related financial benefits available • Supervision: Have your system supervised by Siemens on alarms or unexpected behavior. Own personnel remain for operational work • System support and asset expertise: Have Siemens system experts available on demand for support requests regarding the monitoring system and monitored assets • Reporting: Automated reporting service with or without review and comments from system and asset experts. The reporting provides a solid basis for a structured and condition based asset management approach. The close cooperation between the Remote Diagnostic Center und the Energy Customer Support Center – which processes requests in the field of transmission and distribution 24 hours a day – offers Siemens’ customers one central point of contact. Asset performance management Reliability centered asset management (RCAM) is a leading-edge methodology which combines asset data, subject matter expertise, and several years of experience on assets behavior. This is in order to assess the asset condition and performance, and quantify the associated risk. Reliability Centered Asset Management is a unique software which has been designed as a decision support tool helping asset managers to optimize investment while sustaining targeted levels of network reliability. Reliability centered asset management software calculates the expected performance: • Health indices will be computed to define asset condition • Reliability indices will be computed to define asset importance • Both aspects enable synthesis of optimized asset management strategies. 10.1.4 Cable Services The backbone of the electric power supply consists of high- and medium-voltage cable systems. The limited availability of space and other external factors that restrict the load-carrying capacity of cable systems call for special measures, so that the reliable transmission of electric power can be guaranteed. At the same time, highly specific requirements for the expansion of transmission networks are appearing in Germany and worldwide as a result of the integration of renewable energies. Siemens offers the full range of services for cable systems from a single source, including cable monitoring and diagnostics. Design and accomplishments for high-voltage cable systems As your partner, we offer the full range of services for highvoltage cable systems up to 500 kV, starting with engineering of the cable dimensions up to the final test after installation. Our service comprehends cables with synthetic insulation (e.g XLPE) for various designs (up to 500 kV), low-pressure oil-filled cables (up to 400 kV) and gas-pressure cables (up to 110 kV). Backed by over 150 years of experience, we have an excellent overview of the entire market, and can offer you vendor-neutral advice and support for entire systems and accessories. We employ technologies and high-grade materials matched to your needs for all work activities, from cable laying tools to the professional assembly of fittings with cable-sealing ends and joints. We can also assist you if you are planning to retrofit, convert or extend your system. And if you intend to dismantle an existing installation, we will manage the disposal or recycling of cables and cable fittings. Performing all our work activities in accordance with national and international regulations and guidelines is mandatory for us. Cable measurement Siemens offers cable diagnostics with different detection methodologies, which allow reliable cable condition assessments and ensure exact fault location of installed high- and mediumvoltage cables. Namely partial discharge (PD) diagnostics, dissipation factor (tan δ) measurement, and frequency domain reflectometry (FDR) are offered by Siemens. For the third ­methodology, Siemens uses Line Resonance Analysis LIRA technology. The LIRA system assesses and monitors the general degradation of the cable insulation caused by harsh environmental conditions (high temperatures, humidity, radiation). It also detects local degradation of the insulation material as a result of mechanical impact or local abnormal environmental conditions. These diagnostics services are valuable for specific applications in power transmission and distribution systems, for subsea cable installations like in offshore windfarms, or in oil and gas industry, as well as in power plants. 10 Cable life extension Siemens cable life extension service heals and rejuvenates medium-voltage cables up to 69 kV, insulated with PE, XLPE or EPR. This can extend the lifespan of these cables up to 40 years without the burden of replacing old cables with new ones. Siemens Energy Sector • Power Engineering Guide • Edition 7.1 515 Services & Support 10.1 Asset Services Many medium-voltage cables that were laid in the seventies and eighties are gradually reaching the end of their maximum service lives. This is also true for more recently laid cables that are subject to special aging processes. To prevent any malfunctions in the medium-voltage grid, the affected cables are ­usually replaced. Siemens’ new service for cable life extension offers ­an alternative that can be substantially more cost-effective and time-saving than replacing the entire power cable. 10.1.5 Transformer Services The remaining lifetime of transformers decreases continuously as a consequence of normal ageing processes. The transformer’s rate of ageing varies considerably from one type of construction to the next. It depends on several different facts such as transformer design, capacity, service and load history, climate, and environmental conditions. The critical factors which influence the rate of ageing are: • Operating temperatures (under load, ambient) • Moisture content and increases (e.g., decomposition product of hydrocarbons in insulation) • Oxygen level and inrush (e.g., trough conservator) • Mechanical and electrical stress (e.g., short-circuit events, harmonics, system overvoltage). That is why Siemens offers transformer services including: • Condition assessment and diagnostics • Online monitoring • Consulting and expertise • Maintenance and lifecycle extension • Spare parts, accessories • Repair and retrofit • Installation & commissioning. 10 Planned maintenance and inspection (PMI) Equipment and systems with a long service life and continuous fault-free operation provide the best conditions for efficient utilization of the operator‘s system. Siemens’ maintenance services ensure that all components work safely and reliably, including major revisions and overhauls to bring assets back to reference condition. Siemens keeps customer network assets like switchgear, transformers and the substation secondary equipment well maintained at all times through regular inspections and revisions. Siemens’ Planned Maintenance and Inspection (PMI) comprehends condition-based and preventive maintenance, including recommended spare parts. Repair service and spare parts The primary objectives of the maintenance services offered by Siemens are to avoid emergency repairs and ensure fault-free operations. However, in case of emergency – if a failure occurs – Siemens will be on site rectifying the fault as quickly as possible. Operators can contact Siemens at any time 24/7 via the on-call duty service. An on-call duty contract determines assured reaction times and the scope of on-site emergency measures. The prerequisite for successful and fast fault recovery is, of course, the availability of required spare parts. Siemens delivers spare parts, components and kits for all asset series – from current production to series, which have already been phased-out. In addition, Siemens Transformer Service Programs serve as an umbrella and provide a range of proactive services for all phases of the transformer lifecycle – from a single source, customized, and aligned with each other. For long-term planning, Siemens’ modular designed Strategic Spare Part Solution (SSPS) provides comprehensive consulting services that enable network operators to optimize their spare parts management. For Details please refer to Transformers, Transformer Lifecycle Management. Modernizations and extensions Naturally, the system operator cannot upgrade equipment at the same rapid pace that technology changes. However, Siemens’ modification and retrofit capabilities offer many opportunities for optimization, so that the system operator can benefit from the latest technical improvements. Modernizations and extensions increase the performance of individual assets or complete substations. 10.1.6 Switchgear Services Worldwide customer-focused Siemens service centers are able to manage all product-related services for Siemens products, as well as for Magrini Galileo, Merlin Gerin, Elin Holec, Reyrolle and Allis Chalmers products. Whether in industrial companies, public or private power supply and infrastructure, or building technology – power distribution plants must basically be available continuously, and provide the highest degree of operational safety. Switchgear in particular have to meet the requirements of the steadily increasing demand for electrical energy; but their aging and wear can significantly impact their functioning. 516 Therefore, Siemens switchgear services provide the full range from planned maintenance and inspections, repair services and spare parts, modernizations and extensions up to audits and consulting. Siemens Energy Sector • Power Engineering Guide • Edition 7.1 With these cost-effective solutions, the system operator will be investing capital wisely and taking advantage of the experience offered by Siemens in adapting older systems to new technical standards, resulting in reduced lifecycle costs.

This product and service offering fits perfectly with the meter operations element of the value chain, and enables power generation and distribution customers to manage and maintain their revenue stream. Submetering Siemens provides meter operations services for non-fiscal purposes, including submetering applications. These can be installed and integrated into energy management systems for individual or multi-utility (gas, water, electricity) applications. Siemens provides accurate consumption information at the point of use and visibility via Web-based solutions. Siemens offers tailored solutions and enables the system operator to monitor and control energy usage in different business locations. Large retailers and industrial customers use this service, which can be linked to their billing or finance system. 522 Siemens Energy Sector • Power Engineering Guide • Edition 7.1 Fig. 10.3-3: Q-Smart prepayment meter installed Services & Support 10.3 Metering Services 10.3.2 Data Collection Data collection services comprise meter reading (data retrieval), data processing and data aggregation services. Siemens data collectors carry out routine reads, special request reads and change of tenancy reads as well as re-programming of meters. The data processing system has been developed to comply with strict industry standards and fully supports all work scheduling, validation and distribution of meter readings for up to 12 million meters. To meet special needs and requirements, ad-hoc projects such as providing solutions for “hard-to-read” sites can be performed upon request. The field force consists of 750 Siemens employees. Siemens reads over 14 million residential meter points in the UK on behalf of energy and water suppliers. Systems are continually being enhanced to provide greater flexibility and adaptability, which enables Siemens to meet the constantly evolving market requirements. The automated remote collection systems utilize a range of technologies (e.g., in-field mobile data terminals), providing affordable data collection solutions. 10.3.3 Data Management In this section of the meter-to-cash value chain, Siemens ensures that the data is accurate. That means Siemens aggregates and processes the data, deletes duplicates in the database and verifies the data before passing it on to the system operator. In most cases, the system operator uses this data directly for billing purposes. For commercial and industrial customers, Siemens provides a full range of utility metering data – from electricity to gas and water meters. Large nationwide retail chains are particularly interested in this service so that they can monitor and control the energy consumption of their stores. The IT warehouse enables Siemens to collect a wide variety of data, and Siemens can provide custom-designed solutions based on the operator‘s in-house IT system. Siemens also offers custom-designed reporting systems and works with various communication interfaces to transfer data to the system operator. 10.3.4 Revenue Management In this section of the meter-to-cash value chain, Siemens ensures that the data is meaningful to the system operator. For instance, revenue protection affects the whole value chain – from energy generation, transmission and distribution down to the energy retailers. The key features of the Siemens revenue protection service are investigation of power theft, selective and sensitive targeting and helping to increase the rate of loss discovery, with special focus on high non-residential usage. Siemens packages these features as a non-technical losses solution and offers loss assessments and training to data collection agents. Property management is part of the revenue protection services portfolio. Siemens is a member of the UK Revenue Protection Association and can offer these services internationally. 10.3.5 Smart Metering Smart metering is the combination of automatic meter reading with the ability to control and update the meter point. Having two-way communications between the meter and the central communications “hub” allows data to be collected on demand whilst enabling critical actions to be taken without having to make a visit to the property. It is anticipated that smart metering will drive: • Consumers to become more aware of their consumption and to participate in energy saving initiatives • Energy retailers to bill more accurately with few, if any, estimated readings, and even to forecast and settle their energy based on actual rather than synthesized energy profiles As the global competency center within Siemens for metering services, Siemens has a smart metering portfolio which is “meter independent” enabling a variety of devices to be used for electricity, gas and water metering. Siemens also has the ability to support a number of different communications technologies – GPRS, Power Line Carrier (signaling wire for the low-voltage cables) and fixed radio technologies – depending upon what the customer or market requires. The core of the offering is the smart metering “scheme”. This is a business process solution combining IT technology, business process execution and field force management. The smart metering scheme brings together the data processing and device control systems with business processes designed to optimize the operation of the smart meter asset and the skills to transition from a dumb meter to an installed base of smart meters. Smart metering is an important global trend, and our regional capability and sales network combined with specialist resources makes Siemens the ideal provider of smart metering and smart grid solutions. 10.3.6 Meter Data Management Solution 10 As utilities deploy Advanced Metering Infrastructure (AMI) across their distribution grids, the amount of utility and customerrelated data explodes – from monthly hand-held meter reads to interval consumption received on a 15-minute or less basis. The challenge for the electric, water or gas utility is to convert this massive amount of data into actionable information for multiple purposes across the enterprise. Siemens Energy Sector • Power Engineering Guide • Edition 7.1 523 Services & Support 10.3 Metering Services Siemens provides comprehensive metering and energy information management services to the utility industry, including Meter Data Management System (MDMS) software, integration services, and consulting. Whether the customer’s Smart Grid investment is focused on enhanced meter-to-cash processes to support increased customer choice, or on improvement in customer service, our EnergyIP meter data management platform provides a solid, smart foundation for information management. EnergyIP core functionality EnergyIP captures the complex relationships among devices, premises, customer accounts, users, applications, networks and services that must be managed in any Smart Grid. With its automated process and workflows, EnergyIP provides real-time information and automation to integrate enterprise systems and drive Smart Grid management, acting as the “central nervous system” of your utility. Data synchronization engine The key to providing useful information to all parts of your business is ensuring the data is synchronized across your organization. The EnergyIP Data Synchronization Engine manages the synchronization of data with the AMI, Customer Information System (CIS), and other enterprise applications. The Data Synchronization Engine supports the use of FlexSync real-time web services. FlexSync is an incremental, transactional-based approach to synchronizing data. Changes to master data contained in utility systems (CIS, WMS or other system) are reflected in real-time, keeping EnergyIP up to date with the most recent information. For processes such as meter changes and rate changes, this approach improves billing acuracy, and reduces rework which would be necessary without proper synchronization. Data repository The Metered Usage Data Repository (MUDR) is the data store that maintains the meter readings, register reads, interval records, outage and restoration events, and event logs. The MUDR also maintains derived or computed data, along with trace of versions and audit trails, which is important to keep your auditors happy. 10 The MUDR uses database partitioning to achieve highly scalable performance even with extremely large data stores. In order to meet a typical utility’s AMI system requirements, the MUDR may store and have available on-line any amount of data but typically has 13 to 36 months of meter readings – including daily electric and gas register reads, interval data reads, derived billing determinants, meter event logs, and computed or derived data. Service-oriented architecture The system operator’s meter data management platform needs to be built around a Service-Oriented Architecture (SOA) that integrates all legacy, current and future systems with no loss of data and without the need to update existing systems. The 524 Siemens Energy Sector • Power Engineering Guide • Edition 7.1 energy ­information platform must deliver a consistent way of viewing information across all the types of meters and meterdata c­ ollection systems that might be used in the future. This ensures that system operators do not have to retain all their employees every time a new kind of meter is added. EnergyIP’s open SOA avoids complexity and lowers the total cost of ownership by enabling seamless integration and ­non-­disruptive change within the enterprise’s application ­environment. Workflow engine The Workflow Engine in EnergyIP is a persistent application that maintains and handles requests requiring workflow processing. The engine is also responsible for tracking the progress of open transactions. It tracks the state of each operation, captures time-outs on failed transactions, and progresses the state machine for multi-state operations. Audit tracking We know that keeping good records is serious business. EnergyIP provides extensive logging and audit features in support of system operations and Sarbanes-Oxley requirements. Audit trail is a configurable feature that allows users to choose business components and fields to audit, and to determine the scope of the audit. EnergyIP allows system operators to choose to audit all activity, or to limit the scope of auditing to those operations performed by certain responsibilities, positions, or employees. Reports and reporting framework EnergyIP stores a massive amount of meter read, event, asset and workflow data. But, the data itself is not very useful for decision-making if it cannot be made sense of. In order to mine all of the data to help make better business decisions and find data anomalies and trends, Siemens provides a wide range of standard pre-built reports within EnergyIP. These reports are based on best practice uncovered while working with system operators. The framework also enables to create custom reports, and to configure how and when to receive them. Validation, estimation and editing The EnergyIP VEE (Validation, Estimation and Editing) application performs real-time register read and interval data validation and estimation according to configurable rules. The VEE application also allows graphical editing of metered data. With VEE, the accuracy of interval data can instantaneously be verified, and corrections are possible in real-time. This ensures the availability of the most current and accurate data to drive billing or customer service, and the optimization of just-in-time operations. Analytics foundation The Analytics Foundation for EnergyIP allows to quickly turn AMI data into actionable information that can be leveraged across the utility. The Analytics Foundation is separate from the EnergyIP core transaction database, so that access to near real-time data is possible without compromising operational performance. The data is transformed into a star-type scheme, Services & Support 10.3 Metering Services so that the data can be easily analyzed and reported by using the reporting tools included in EnergyIP or any other reporting / BI tool. 10.3.7 Demand Response Management Software Demand response refers to all functions and processes applied to influence the behavior of energy consumption. This can range from simple signaling, e-mail, SMS, or a phone call to a person who switches a load on or off, to fully integrated load management, where many consumption devices are dynamically controlled according to availability, or to the price of energy. Since the demand for electrical energy in many cases is closely connected to the demand for alternative forms of energy, heating and cooling energy, or mechanical energy, demand response solutions must reach far beyond the electrical grid itself. In particular, optimization must include all energy forms which are interconnected. Siemens Demand Response Management System (DRMS) is a proven software platform that allows utilities, retailers and aggregators to manage all aspects of their Demand Response (DR) programs through a single, unified, open-standards-based system. Siemens DRMS solves the challenge of creating a cohesive and comprehensive solution by: • Ensuring DR capacity is scaled in a cost effective manner; automating the manual processes that are typically used to execute DR events and settlement • Fully integrating with both field and back-office utility systems to leverage investments in Smart Grid technology • Intelligently targeting “surgical” planned load curtailments at localized grid environments where localized grid stress is present. World view on DRMS Demand response is an ever evolving topic with respect to today’s environment. Business, operations, and regulatory needs are consistently changing and, as a result, the value of demand response resources has become increasingly important. Integrated and automated demand response technology improves not only a consumer’s capability to reliably participate in DR programs, but also allows a utility to better utilize and optimize the consumer DR loads, both holistically and “surgically”. As such, utilities are able to leverage demand response for activities such as near real-time load balancing and frequency regulation, and other types of ancillary services. secure, web-based interface allows access from multiple locations with role-based access and full auditing of system activities. The interactive customer portal increases performance by showing customers their historical results and real-time feedback during DR events. Evolution and innovation for the future As the field of demand response continues to mature, enabling technologies allow DR further extend the value of utility assets. Siemens DRMS makes it easier to maximize the value of each DR resource, and minimize DR operational costs through more efficient processes and process automation. • Ensures committed reduction levels are met by providing a forecast of both connected and sheddable load, thereby increasing reliability and reducing uncertainty • Includes added support for DR program definitions and thirdparty integration, and event notification allows many types of programs and consumer classes to be managed through a single application in a more cost-effective manner • Extends the number and type of business processes that can be mapped into the DRMS via configuration, not through expensive customization. This capability allows for increased operational efficiency by dispatching DR programs and assets in a consistent and logical manner, while also providing more accurate results over time. A real-world illustration An excellent illustration of how the Siemens DRMS works and delivers benefits can be seen at an east-coast generation and transmission (G&T) operator that has adopted the use of this DRMS technology to implement targeted load reductions. This G&T has limited generation capability and procures much of its supply through bi-lateral power purchase agreements or through the wholesale markets. In times of peak demand, the G&T is forced to procure expensive peaking power to meet demand. Their goal was to utilize technology to help alleviate grid stress and reduce the need to purchase expensive power through the use of demand response technology. Using the Siemens DRMS, the G&T was able to create several demand response programs to operate within their three main operating territories. They are also using Siemens DRMS to create and manage load control groups based on zip codes and several other attributes, which allows them to effectively manage peaks for each of their participating member coops at the substation level. In roughly eight months, they enrolled 50MW of load reduction capacity – equivalent to nearly half the capacity of a typical natural gas-powered peaking plant. Not only has the G&T been able to reduce power purchase costs, but they anticipate reduced operations and maintenance costs as well. 10 A proven and reliable application Siemens DRMS has successfully been deployed at several utilities, each with their own unique requirements, using open protocols and standards like MultiSpeak and OpenADR. Siemens DRMS is both reliable and scalable, supporting over several hundred thousand endpoints per customer class. The Siemens Energy Sector • Power Engineering Guide • Edition 7.1 525
