智能变电站仿真试验系统开关量信号接口方法

Study on Methods of Switching Signal Interface to Smart Substation Simulation Test System

智能变电站二次试验系统与电网数字仿真系统相联接时,可能存在开关量信号不匹配的问题。针对该问题,本文介绍了两种解决方案,一种是外接模拟断路器的硬件方案,另一种是构建开关控制回路模型的软件方案,并以试验为例验证了以上两种方案的有效性。

There may be a switching signal mismatch problem in communication of the smart substation test system with the advanced digital power system simulator （ADPSS）. Two methods are introduced in this paper to resolve the mismatch problem. One is a hardware solution by adding an analog breaker, and another is a software solution by designing a switch control circuit model. The feasibility of both methods are demonstrated in case studies on a realistic project.
