OPAL-RT RT13: Relay testing with HYPERSIM
1 like652 views
Relay Testing with HYPERSIM allows for more advanced testing of relays using a simulator rather than traditional open-loop testing. A simulator provides closed-loop testing where the relay response feeds back into the simulation, allowing testing under critical conditions. It offers benefits like evaluating new protection algorithms, studying complex protection schemes, and analyzing interactions between real and virtual relays. Key features include detailed EMT analysis, automation of test sequences, and the ability to simulate faults, disturbances, and communications protocols like IEC 618450.

- 1. Relay Testing with HYPERSIM by Vincent Lapointe for Etienne Leduc June 26, 2013
- 2. Content • What are new challenges? • Why using a simulator? • What would be the benefits? • Some features ... • Use cases • Showtime
- 3. Traditional Testing Approach • Open-loop testing – playback EMT simulation or – replay the field-recorded data • Omicron, Doble, Megger test sets • Sets a fixed voltage and ramps current from 0 to relay operates • Repeats such a test for several operating points
- 4. What are new challenges? • New type of applications : smart grids, microgrids, DER • New protocols : IEC-61850, MMS, C37.118, DNP3, ... • Increased number of functions • More complex relay characteristic • Different vendors have different operating philosophies and algorithms • New type of equipment installed : merging unit, pdc, ...
- 5. Why using a simulator? • Closed loop testing : response of the IED under test is fed back into the simulator and possibly affects the simulation • Perform detailed EMT analysis and testing • Evaluate relay performance under critical conditions , while it is in service • Develop and prototype new protection algorithm (RCP) • Study complex protection scheme and see interaction of real and virtual relays and their behaviour altogether. • See interaction between relays and power electronic equipment such as HVDC, FACTS,
- 6. What would be the benefits? • Purchase the best products for a given application • Make sure the installed equipment is operating correctly • Analyze any problems efficiently and in great detail • Demonstrate to a regulator a reliable (selective) performance • Identify abnormal behaviour of power system or protection and control equipment • Study more application cases
- 7. Some features ... • Models – Simulate large grids with loads, generators, transformers, lines, motors,... – Simulate complex power electronic converters – Simulate CT, PT – Simulate virtual IED and new type of protection – Relay library • Simulate various type of faults and of power disturbances – fault location, fault type and fault interception – Apparatus internal fault
- 8. Some features ... • Test Automation – Automate test sequences – Monte Carlo analysis – Playback recorded data from field – Scripting and macro recording – Import and export various file format such as COMTRADE – Produce report automatically

- 10. IEC 61850 comm. Interface
- 11. Protocol IEC 61850 IEC 61850 is are international standards defining: • how to describe the devices in an electrical substation • how to exchange the information about these devices 2 types of messages: • Sampled Values (SV) • Generic Object Oriented Substation Events (GOOSE)
- 12. Model Fault group 1: Overcurrent fault Fault group 2: Overvoltage fault Simplified Hydro-Quebec’s network
- 13. Corresponds to a bus redundancy configuration Fault 1: Overcurrent
- 14. Fault 1: Overcurrent 1. Bus-to-ground fault, 1 or many phases 2. Bus MTL735_1 is disconnected and power flows on bus MTL735_2 1 2
- 15. Fault 2: Overvoltage 1. A 3000 MW load is disconnected, voltage increases 2. Ten 330 MVAR inductances are connected to bring the voltage back to 1 pu 1 2
