Siemens Microcontroller For SGT-100 & SGT-200 Industrial Gas Turbines Answers for Energy Siemens has developed an upgrade for the Rustronic MKII Control System based on the globally available Siemens S7-300TM controls processor family. HMI display provides operational status of the turbine with userfriendly mimics & messages It is designed specifically as an upgrade replacement to existing SGT-100 and SGT-200 gas turbine control systems and will provide a high level of functional flexibility, with improved reliability and availability, which will also enable access to a range of other benefits. Provides the operator with a first line diagnostic tool to reduce any unscheduled down time The use of the new systems will also allow wide-spread local support coverage through Siemens Regional Support Centres. Technology Siemens S7-300TM control processor and touch screen HMI (Allen Bradley controls can be offered on request) Replacement control cabinet/s offer standard configuration of preengineered modules Replicates the original control system, including interfaces for safety interlocks to other customer equipment Provides for control of gas turbine operation on existing fuels Cabinet and display screen text will be in English, other language options available, at additional cost Abnormal conditions displayed as time tagged alarm or trip message Functions The Microcontroller includes the following turbine control and monitoring functions: Turbine start, stop and shutdown sequencing and protection Instrument fault monitoring Message annunciation Turbine speed control and protection Turbine temperature monitoring and protection Turbine lubrication oil control and monitoring Off-package gas fuel, block and vent valve control (if installed) Fuel system control and monitoring Ignition control Vibration monitoring interface Fire & Gas monitoring interface Microcontroller provides for retention of the driven unit interface www.siemens.com/energy Benefits Options Improved reliability: results in fewer spurious trips Improved availability: due to enhanced diagnostics, easier repair, dependable spares supply and support network Obsolescence Cost Reduction Improved Operator interface: provides comprehensive information on the major systems and reduces operational errors Enhanced fault response: Improved response to abnormal situations through the use of “Calm Controls” methodology delivering increased uptime of the turbine package Enhanced diagnostics: Clear and comprehensive on-screen status displays Improved accuracy & stability: allows maximum use of the operational envelope Enhanced communications: through use of widely accepted networking protocols Distributed I/O compatible: reduces on site wiring Display A touch screen is used to provide an easy to use operator interface. Screens are provided to display information in various formats, including pictorial and tabular. Status pages showing live information can be selected for critical turbine and driven unit parameters. Although the design is standardised, a range of preengineered options allow for considerable flexibility in meeting the specific needs of individual customers. Health & Safety Benefit by Mods & Ups Reliability Various options are available to further enhance the package including: Performance Fuel system upgrade Environment Block and vent valve replacements Distributed Control System Data Link The control system can be supplied with a communications data link for connection to a station control panel or Distributed Control System (DCS). A number of communication protocols can be provided. Vibration monitoring systems Instrumentation upgrades Enhanced HMI packages Connections to external communications systems via electronic data network Fire & Gas systems NOx reduction & power enhancements Associated modernization and upgrades: Turbine Temperature Monitoring The visual display shows a mimic with separate thermocouple values, an average of PT Exit temperatures and a deviation bar graph. The system provides some redundancy as two adjacent thermocouples must fail before a trip is initiated; failure of a single thermocouple is indicated as a warning and displayed on the gas path mimic. The system provides alarm and shutdown monitoring on maximum combustion cycle temperature, deviation limit and PT Exit temperature.
