摘要
IEC61850继电保护试验装置大量应用于智能变电站的继电保护测试,文章梳理了影响试验装置性能的三类关键指标:数值计算能力、输出同步性、时间测量和控制准确度,由此制定了试验装置的技术指标,对每个指标确定了典型的检验方法。组织了国内主流试验装置开展集中测试,结果证明了关键指标的合理性及检验方法的适用性,为智能变电站继电保护试验装置技术标准的制定打下了理论和实践基础。
IEC61850 test equipment for relay protection is widely used in intelligent substation. Three key indexes of the tester are proposed, the numerical computation ability, the data outputs synchronization, and the precision of time for measurement and control. Technology indexes and testing method of the tester are set in this paper. The mainstream testers are tested and the results indicate that the rationality of key indexes and the applicability of testing method, that lays the theoretical and practical foundations for the technology standard of relay protection tester of intelligent substation.
