Power & Energy Value Stream 3 1 Utility Power Gen <50MW, Renewable sources & energy storage 4 2 Utility Distribution Substation Power Quality Monitoring 5 Utility Distribution Branch circuits, last mile PQ and energy services Industrial & Commercial Energy & PQ Monitoring Workflows where monitoring power quality is integral to Utility management and QA or Industry operations uptime and Opex spend • Utility system planning, demand management and PQ analysis. – The task of understanding power consumption to ensure the distributed power meets the ever-growing needs of industry and the consumer. • Industrial and commercial facility electrical infrastructure, m onitoring power at main service entrance and critical branch circuits – Mitigate power quality issues that disrupt company operations – Trend energy consumption trends, identify waste and savings opportunities 40 40 20 2/22/2021 Standards – EN50160 What is EN50160? • The EN50160 standard is used across Europe to describe the allowable levels of power quality provided by electricity distributors, it includes a range of measured variables and the allowable level for each individual measured parameter, these include: – Frequency – Short interruptions – Long interruptions – Flicker PST – Flicker PLT – Interharmonic voltage – Temporary overvoltages – Voltage dips – Voltage variations – Harmonic voltages – Mains signaling voltage – Rapid voltage change – Voltage unbalance The power quality is measured at the point where the utility transfers power to the consumer, at the point of common coupling (PCC), where the utilities revenue meter is typically located. The EN50160 has some serious limitations, it includes a significant amount of time during the any seven days period when power quality does not have to meet the allowed level for many hours per week. The described levels are useful for all users as a basic description of the power quality state of health. Applies to HV, MV and LV networks with different allowable levels at each voltage EN50160 is used more as the starting point of negotiation with the power utility and consumer rather than a minimum quality standard the utility agrees to. 41 41 Standards – IEEE519 What is IEEE519-2014? • The IEEE519 relates to the distortion requirements when installing harmonic loads on the power network. • The standard details the allowable voltage and current distortion limits allowable at the point of common coupling • Different voltage distortion limits apply at separate voltage levels of: 1kV, 1kV to 69kV, 69kV to 161kV and over 161kV: • The current distortion limits apply at a different set of voltage levels: 120V to 69kV, 69kV to 161kV and over 161kV • During testing the load is operated to discover the level of distortion created during typical operating cycles. Harmonic loads within this context are non-linear loads such as static power converters, arc discharge devices, saturated magnetic devices, and, to a lesser degree, rotating machines. Nonlinear loads change the sinusoidal nature of the ac power current (and consequently the ac voltage drop), thereby resulting in the flow of harmonic currents in the ac power system that can cause interference with communication circuits and other types of equipment. 42 42 21 2/22/2021 IEEE519 – Limit Examples Voltage harmonic limits for all voltage level Bus voltage V at PCC V ≤ 1.0kV 1kV < V ≤ 69kV 69kV < V ≤ 161kV 161kV < V Individual Harmonic (%) 5.0 3.0 1.5 1.0 Total Harmonic Distrortion THD (%) 8.0 5.0 2.5 1.5 Current harmonic limits at 69kV to 161kV: ISC/IL <20 20 < 50 50 < 100 100 < 1000 >1000 Maximum harmonic current distortion in percent of IL Individual harmonic order (odd harmonics) a, b 3≤ h <11 11≤ h < 17 17≤ h < 23 23 ≤ h < 35 35≤ h ≤50 2.0 1.0 0.75 0.3 0.15 3.5 1.75 1.25 0.5 0.25 5.0 2.25 2.0 0.75 0.35 6.0 2.75 2.5 1.0 0.5 7.5 3.5 3.0 1.25 0.7 TDD 2.5 4.0 6.0 7.5 10.0 The IEEE519/Report software module direct compares the measured values with the limits of the standard to produce detailed reports in the minimum time. 43 43 IEC61000-4-7 - Harmonics • The IEC61000-4-7 standard is a general guide on harmonics and interharmonic measurement and instrumentation for power networks • It describes in detail the methods that should be used for measurement and classification of the measured values of harmonics and interharmonics • In addition to the main standard there are two additional annex documents that describe the measurement of interharmonics and harmonics in the frequency range above 9kHz. • These two documents are informative, that is that are not strictly part of the standard. • The standard does include a variety of limits that other standards specify in a number of examples to show how the standard is used but nominally does not have built-in limits. These standards include: • IEC 60038 • IEC 61000-2-2 • IEC 61000-3-12 • IEC 61000-3 series (various standards) The purpose of this standard is to ensure that measurements of harmonics are consistent by various measurement instrument so that results can easily be compared when multiple instruments are used. 44 44 22 2/22/2021 IEC61000-4-15 / IEEE1453 Flicker • The IEC61000-4-15 and IEEE1453 describe the methods of measurement of flicker in power systems. • Flicker is caused by fluctuations in the power system voltage which result in observable changes in the light output of electric lamps. It can be an annoyance and hindrance to workplace productivity and visually affect susceptible individuals. • The fluctuation may also cause detrimental effects to electrical equipment such as nuisance tripping of breakers, unwanted switchover in UPS systems and problems with sensitive electronic equipment that need constant voltage (e.g. medical equipment) • The basic measurement of flicker is PST, short term flicker and PLT, long term flicker. Short term is considered over a 10 minute period and long term over a 2 hour period. • A PST value of 1.0 for flicker represents a figure that 50% of people would perceive flicker in a 60W incandescent bulb. Although incandescent bulbs are used less frequently the overall effect of flicker remains present on other lighting and equipment. • The two standards are almost identical, the IEC standard refers to 230V operated system and the IEEE refers to 120V operated systems. The typical source of voltage flicker comes from randomly operating loads such as arc furnaces, welding machines, intermittently starting and stopping induction motors. 45 45 IEC61000-4-30 • The IEC61000-4-30 standard describes the measurement and testing methods to be used by power quality measurement instruments. It allows two classes of instruments, Class A and Class S. • Class A offers the best accuracy and Class S is considered to be acceptable for regular power quality surveys. • The main differences in accuracy are in the measurement of voltage and time. For Class A, voltage accuracy of 0.1 % of declared input voltage UDIN over the range of 10% to 150% of UDIN is required • For time accuracy, ± 20 ms for 50 Hz and ± 16.7 ms for 60 Hz is required regardless of the total time interval. Achieving this accuracy requires either a GPS clock via a GPS receiver or NTP (Network Time Protocol) via Ethernet • The standard describes the method required for measurement (as per IEC61000-4-7 and -15) and dictates the methods used for classification and flagging of specific items to enable consistent reporting. • The Fluke 1740 series will be independently verified to comply with Class A by an external agency. Class A is particularly useful in dispute resolution between the power supplier and the consumer, the higher accuracy requirements for Class A analyzers enables both user in the dispute to make measurements that will be identical. 46 46 23 2/22/2021 Class A Data Aggregation: • Data is specified to aggregate at multiple rates depending upon the logged value. The primary aggregation periods are: • 150/180 cycles (150 cycles for 50Hz and 180 cycles for 60Hz) • 10-minute interval • 2-hour interval (note that the 10 minute and 2-hour periods are those specified for flicker in IEC61000-4-15) • The 10-minute interval is the one which most data is represented by, each 10-minute interval is made up multiple 150/180 cycle periods Event Capture • The identification of the time stamp of events (any significant change in the voltage) is made based on the occurrence of the event with a half-cycle trigger – that is a half cycle RMS voltage outside of limit will be classified as an event. • To identify the occurrence of an event each part of the event is ‘flagged’ to indicate that item is part of one event – this is to ensure that the effects of the event are consolidated into one for simplicity of analysis. 47 47 Measurement Standard Summary • The prevailing standard for power quality can be split into two areas: • Measurement and evaluation (for equipment) • IEC61000-4-7 (Harmonics) • IEC61000-4-15 (Flicker) • IEC61000-4-30 (Methods) • Evaluation of logged data against limits • EN50160 • IEEE519 • GOST (Russian standard) • This is not a comprehensive list of standards for power quality, but these are most frequently quoted standards. • In many cases there a geographical adaptation of the standards which evaluate against limits which use locally defined limits, the Fluke 1740 series have adjustable limits to adapt the instrument and reporting to these situations. • There are also localized reporting standards that can be configured within the instrument and in reports in the application software. The purpose of any standard is to ensure that repeatable results are being created every time, whether that be in the measurement and evaluation of data or whether that is in the evaluation of data against allowable limits. 48 48 24 2/22/2021 What are the harmonics ? • In a normal ac power system, voltage varies sinusoidal • With non-linear loads such a rectifiers and switches, the current draw is not necessarily sinusoidal • The waveform is then complex • The complex waveform can be decomposed into individual sinusoidal components • These harmonic components impact motors, transformers, cabling and other electrical components 49 Identifying harmonics waste Power quality analyzers display a spectrum graph of harmonic components present in a system, but the graph on its own does not quantify the amount of energy wasted by harmonics. Harmonics cause: • unusable power, drawn from utility but not converted to actual work • high current to flow in neutral conductors • motors and transformers to run hot, decreasing efficiency and shortening lifespan • increased susceptibility to voltage sags • reduced transformer efficiency — or, a larger unit is required to accommodate harmonics. 50 25 2/22/2021 The insidious 3rd harmonic Technical lesson 400 300 200 100 0 -100 0 -200 -300 -400 On a three-phase / four-wire system, triplen (zero sequence) harmonics will add up in the neutral.

Loss of generated electricity of approx. 1,000 USD per minute for a medium sizes power generation facility. • Additional costs for repairs and equipment damage • Energy waste • High penalty from government • Undetected PD will cause arch flash or even explosion → Safety risk for human and equipment 57 Ii910 Real Application – Detecting PD in Transformer 58 58 29 2/22/2021 Ii910 Real Application - Inspecting PD in Electrical Distribution System Detection of Partial Discharges and Arcing in HV/MV electrical cabinets and on busbars ❑ Safety: able to detect from safe distances ❑ Effective and fast in location of PD ❑ Easy to use with minimum training required ❑ Documenting with pictures 59 Ii910 Real Application - Inspecting PD in Electrical Distribution System Detection of Partial Discharges (and Corona) on Distribution Lines and Switchgears ❑ More effective in outdoors than ultrasonic tools ❑ Fast routing ❑ Easy for untrained users ❑ Documenting with pictures Inside of the cabinet with severe PD 60 30 2/22/2021 Battery Health Prediction 61 • Power protection systems in medical institutions have higher standards than those for commercial or industrial use Under most circumstances, a hospital losing power could be the difference between life and death for any number of patients who are reliant on its systems functioning at optimum levels. • Batteries operate by converting chemical energy into electrical energy through electrochemical discharge reactions. • Batteries are composed of one or more cells, each containing a positive electrode, negative electrode, separator, and electrolyte • Batteries are rated in terms of their nominal voltage and ampere-hour capacity Type of Battery 62 62 31 2/22/2021 + = RSOB operation Switch with one button and continue at break point + Meter mode for quick ad-hoc battery test Dual mode combines the simplicity of DMM and functionality of string data management.
