| 摘 要： | 介绍一种基于PWM技术的新型静止无功补偿器。研究该补偿器在稳定系统电压方面的作用,分别对它在小扰动和大扰动情况下的工作状况进行分析,证明在工作范围内新型静止无功补偿器对系统电压有很大的支撑作用,可有效稳定系统电压。该补偿器具有结构简单、控制方便、响应速度快等特点。采用单机无穷大系统对补偿器进行开环和闭环控制仿真研究,验证该补偿器能维持装设点的电压并提高其电压稳定性。

| Abstract: | A novel static var compensator based on PWM technology was introduced.Voltage stabilization of power systems by using a novel static var compensator was studied and operation situation under a small or a big interference was analyzed.The novel static var compensator can effectively control power system voltage and has a great sustentation for power system voltage in the normal work condition.The compensator possesses following features: easy to control,simple structure,high response speed,etc.The simulation study of effects of open and close loop controls for the novel static var compensator with a single machine to an infinite bus system verifies that this compensator can maintain the voltage at the setting up point and improve power system voltage stability. |
