摘要(Abstract)：

通过分析配电网静止同步补偿器(distribution static synchronous compensator,DSTATCOM)的输出电压与电网电压的相角差δ与装置吸收的无功功率和有功功率的关系,建立了DSTATCOM稳态逆系统数学模型。提出以稳态逆系统数学模型为主控制器、电流反馈闭环控制为辅助控制器的双变量(δ和M)电流控制策略,并通过调节δ角控制直流侧电容电压。同时在补偿电流与直流侧电容电压控制中引入非线性PID控制技术,使得装置具有很好的自适应能力。最后经DSTATCOM模拟装置证明了所提控制方法的可行性和有效性。

关键词(KeyWords)： 配电网静止同步补偿器;逆系统模型;双变量;非线性PID控制
