摘要
RTDS(RealTimeDigitalSystem)能够比较真实地反映实际电力系统的故障性征,且具有一些模拟动模试验系统不能实现的性能,使其在高压线路保护装置的研制及开发过程中发挥着重要的作用。介绍高压线路保护装置动模测试的模型及要求的同时,着重分析了当前高压线路保护装置研究的几个难点,并就此给出了在研制新一代高压线路保护产品DF3621中的处理策略和方法。大量的RTDS试验表明,DF3621对于特殊工况、转换性故障等方面表现良好,能够满足高压线路对保护的要求。
RTDS(Real Time Digital System) can simulate fault characteristics of the real power system, which is superior to that of analog dynamic simulation system. Because of its characteristics, RTDS plays an important role in the research and development process of extra-high-voltage(EHV) line protection. This paper introduces the test model and requirements of EHV line protection, and analyzes several difficulties of line protection devices in detail. Scheme and method for these problems in developing new high voltage line protection DF3621 are presented. Lots of RTDS test results show that DF3621 has high reliability and satisfactory performance to special operating conditions and translating faults.
