摘要 设计了一种模块化多电平柔忡直流输电阀控测试系统,包括极控模拟装置、换流站主电路信号发生装置、换流阀子模块模拟装置和临控后台等、该测试系统可以在不使用极控系统和换流阀本体的条件下,定成对模块化多电平柔性直流输电阀控系统的基本功能测试.包括子模块电容电压的读取和状态监视、均压控制、阀控对子模块故障处理逻辑、阀控自身故障处理逻辑、系统电压电流的采集等。仅需凋整子模块模拟装置的接口数量.即可满足不同容量和电压等级的柔性直流输电阀控系统测试需要、对MVCE300型柔性直流输电阀控系统进行了实际测试.测试结果表明.该测试系统町以满足秉性直流输电阀控设备厂内调试的需要。 A testing system for modular multi-level converter HVDC flexible valve control equipment has been designed,which consists of simulation device for pole control,main circuit signals generator for converter stations,simulation device for valve sub-module and background monitor.This testing system can carry out the basic functional testing,including capacitor voltage reading and valve status monitoring,voltage sharing control,sub-module fault processing logic,valve control device fault processing logic and analog signal acquisition,of the modular and multilevel HVDC Flexible valve control device without the pole control system and converter valve.And it can meet the testing requirement of MMC HVDC flexible valve control device with different voltage classes or transmission capacity,by just adjusting the interface numbers of the simulation device for valve sub-module.A MVCE300 valve control device was tested and the testing result shows that the testing system can meet the testing need of modular multi-level converter HVDC flexible valve control equipment.
