摘要

实时数字模拟器与电流和电压放大器相结合，为在尽可能接近现实的条件下对现代基于微处理器的继电器进行详细测试提供了机会。测试数字线路电流差动保护系统产生了具有挑战性的问题，因为许多与通信相关的测试场景应该结合电力系统干扰进行检查。本文提出了一种测试二端和三端线路电流差动系统的方法。还包括测试数字继电器的样本测试结果和一些建议。使用实时数字模拟器(RTDS)和通信数据链路模拟器(CDLS)作为测试工具。

Testing line current differential relays using real-time digital simulators

Real-time digital simulators in conjunction with current and voltage amplifiers offer an opportunity for detailed testing of modern microprocessor based relays in conditions as close to realistic as possible. Testing a digital line current differential protection system creates challenging problems as a number of communications-related test scenarios should be examined in combination with power system disturbances. This paper presents a methodology for testing 2- and 3-terminal line current differential systems. Sample test results and a number of recommendations for testing digital relays have been included. The Real-Time Digital Simulator (RTDS) and Communications Data Link Simulator (CDLS) were the testing tools used.
