Opis:
Software power protection tester implemented in a real-time operating system (RTOS) might replace the conventional testing setups in IEC 61850 protection systems. This paper describes an open power protection testing platform. Linux RT capabilities related to runtime environment for such a tester are examined and OS latency sources are identified and evaluated. An algorithm for a multithreaded tester operation is proposed, including Sampled Values (SV) publisher, GOOSE input/output and time synchronization. SV and GOOSE services implemented in RT Linux environment are evaluated in accordance with IEC 61850‒5 transfer time requirements. Linux PTP time synchronization service of two similar systems controlling its electrical ports is evaluated in different synchronization scenarios. The developed tester is compared to an equivalent conventional setup during the test of IED over-current function. The conducted tests show that the Linux implementation of power protection tester in the case of scheduler latency, time synchronization accuracy and transfer time all meet the requirements of IEC 61850.

Opis:
Real time simulators of IEC 61850 compliant protection devices can be implemented without their analogue part, reducing costs and increasing versatility. Implementation of Sampled Values (SV) and GOOSE interfaces to Matlab/Simulink allows for interaction with protection relays in closed loop during power system simulation. Properly configured and synchronized Linux system with Real Time (RT) patch, can be used as a low latency run time environment for Matlab/Simulink generated model. The number of overruns during model execution using proposed SV and GOOSE interfaces with 50 µs step size is minimal. The paper discusses the implementation details and time synchronization methods of IEC 61850 real time simulator implemented in Matlab/Simulink that is built on top of run time environment shown in authors preliminary works and is the further development of them. Correct operation of the proposed solution is evaluated during the hardware-in-the-loop testing of ABB REL670 relay.
