论述了调相机建模的必要性,从调相机变压器组关键设备建模、调相机动模系统设计入手,研究了调相机保护测试技术,并搭建了调相机动模测试平台,该平台包括SFC变频启动装置和注入式定子接地保护回路。测试结果表明,该动模系统可准确模拟实际调相机的故障暂态特性,能够有力支撑调相机保护性能的分析与测试。

This paper discusses the necessity of synchronous condenser modeling and investigates synchronous condenser protection testing technology based on key equipment modeling of synchronous condenser trans-former bank and dynamic simulation system design;besides,it builds a dynamic simulation test platform,which is composed of SFC(static frequency converter)and injected stator grounding protection circuit.The test results show that the dynamic model system can accurately simulate the fault transient characteristics of the actual synchronous condenser,and can effectively support the analysis and test of the protection perfor-mance of the synchronous condenser.
