1 Working Group Meeting North American SynchroPhasor Initiative June 8-9, 2010, Vancouver, British Columbia Wide area monitoring and control activities in Norway and the Nordic power system Kjetil Uhlen, NTNU Norwegian University of Science and Technology, (and SINTEF Energy Research) Norway 1
2 Outline The Nordic power system WAMS activities, objectives and applications Power oscillation monitoring PMU measurements On-line monitoring From WAMS to WACS.. (ongoing and future work) Concluding remarks 2
3 Outline The Nordic power system WAMS activities, objectives and applications Power oscillation monitoring PMU measurements On-line monitoring From WAMS to WACS.. (ongoing and future work) Concluding remarks 3
4 The Nordic Power system Norway (TSO Statnett): Regional control centres National control Centre - Oslo 4
5 Nordic system dynamic characteristics Modal Analysis: Identified and classified oscillatory modes Oscillatory Frequency Relative Damping Mode Classification Main Observability Area 0.33 Hz 5.40 % Inter-area mode Finland / Southern Norway 0.48 Hz 2.48 % Inter-area mode Sweden / Southern Norway 0.55 Hz 3.39 % Local area mode Northern Norway 0.62 Hz 6.20 % Inter-area mode Sweden / Central Norway 0.76 Hz 1.48 % Local area mode Western Norway 5
6 Outline The Nordic power system WAMS activities, objectives and applications Power oscillation monitoring PMU measurements On-line monitoring From WAMS to WACS.. (ongoing and future work) Concluding remarks 6
7 Statnett s assessment of potential benefits and applications of WAMS Workshop at Statnett in 2006 to assess promising functions and benefits In operation Operation planning For protection and fault analysis On-line functions Various displays and indicators Power oscillation monitoring, voltage instability, voltage flicker,.. Off-line functions Plotting and display functions Analysis tools Trigging functionality (for identification of events and storing data) 7
8 Main findings On-line information and trending of complex information is not considered as very useful. Operators do not have time to look at this information, especially not in stressed situations. Simple alarms and information quantifying presence and characteristics of power oscillations is useful. Such information is not available today. On-line calculation of high voltage flicker levels is useful in some substations. Off-line: Good tools for storing, displaying and analysing phasor data are important. Useful for many off-line analysis purposes, including forensic analyses and model validation. 8

12 Comparing Phasor Measurements with EMS- State Estimator - Voltage angle differences 12
13 Measurements from a disturbance in the Nordic grid on August 14, 2007 What system information can be obtained from the PMUmeasurements? What is the additional information compared to available SCADA-measurements? What is the additional benefit of WAMS? 13

22 When/how to utilize PMUs and WAMS for power system control? When there is a need for system wide information (more than just local information) AND high resolution dynamic information AND/OR time synchronized measurements Power oscillation damping Voltage collapse protection (based on fast detection of voltage instability problems) Frequency instability (out of step) protection Emergency control / System protection schemes How: Power system stabilisers (coordinated design) Control of SVC/FACTS and HVDC (active and reactive power control) Generator tripping / Load shedding Network splitting (breaker control) 22 22
23 Kvandal Wide-area POD Goals: Study the use of PMUs as measurement signals, Investigate coordinated stabilizer design, using SVCs Identify benefits and challenges with wide area measurements, compared to traditional local measurements SVC Røssåga SVC Tunnsjødal SVC Verdal SVC Viklandet SVC Sylling SVC Hasle SVC Rød SVC Kristiansand SVC 23

25 Time Domain Simulations Small Disturbance Large Disturbance Active power flow: Norway-Sweden: Black curve: No PSS Red curve: WAMS Single-tuned PSS: Sylling (0.33 Hz) & Rød (0.48 Hz) Blue curve: Local Single-tuned PSS: Sylling (0.33 Hz) & Rød (0.48 Hz) 25
26 Result and Conclusions Stabilizers with local or wide area measurements considerably improves damping of inter-area power oscillations Wide-area solution can be more robust with better performance for wider range of operating scenarios and subject to larger disturbances Remote PMU measurements enhances observability Simplifying stabilizer design Improving damping on wider range of modes Potential PMU challenges: Availability and communication delays Suggested solution: dual input solution Possibility of fall-back to local signals Provides increased robustness 26

32 Experiences and concluding remarks Several WAMS-applications have been assessed and tested by STATNETT Power oscillation monitoring (POM) is considered most useful by operators POM for post-disturbance analysis is demonstrated: Cause of oscillations easily identified from PMU measurements Promising experiences with on-line POM Amplitude, frequency and damping signals are robust when needed SVCs are shown to provide significant controllability on power oscillations: Implementation and testing of a Wide area POD is ongoing. 32
