摘要(Abstract)：

根据低压变频器电压穿越能力要求和发电厂一类辅机低压变频器配置特点,提出了基于电力电子技术的测试系统电压暂降、暂升发生装置设计思路。对测试系统的变频器负载配置方案进行对比分析,并对不同类型的辅助电压支撑装置测试时的电源要求进行了探讨。最后提出低压变频器及其在辅助电压支撑装置配合下的高、低电压穿越能力测试系统拓扑结构、配置方案、参数要求和功能设置,形成了一整套的测试系统设计开发方案。
According to the requirements on voltage ride through capacity(LVRT) of low voltage frequency converter and the current configuration characteristics of low voltage frequency converter of power plant auxiliary machinery,the paper proposes design idea of test system voltage sag and swell generator based on power electronic technology. Frequency converter load configuration scheme of test system is contrasted and analyzed; besides,power requirements of different types of auxiliary voltage support device are discussed. Finally,this paper proposes topology,configuration scheme,parameter requirements and function setting of low voltage frequency converter and its high/low voltage ride through capacity test system with the coordination of voltage support device,forming a complete design and development scheme of test system.
