摘　　要：提出将电压源型变流器(voltage source converter,VSC)应用于电力扰动发生装置的构想,阐述了该装置的拓扑结构与工作原理,根据运行工况确定该装置主电路参数。建立了在dq坐标系下的装置数学模型,基于非线性微分几何理论中的状态反馈线性化方法实现了dq轴电流的解耦控制;利用PI环节优化控制器动态性能,采用零极对消法和极点配置法对PI参数进行整定,实现了直流侧电压稳定的目标;采用正弦脉宽调制方法实现对电力扰动波形的灵活订制。试验结果表明,并网运行后该装置运行平稳,实现了电力扰动波形的稳定输出。The idea of applying voltage source converter(VSC)to power disturbance generator is proposed.The topological structure and working principle of the device are described,and the main circuit parameters of the device are determined according to the operating conditions.Based on the state feedback linearization method in nonlinear differential geometry theory,the dq axis current control is realized.The dynamic performance of the controller is optimized by using the PI link,and the PI parameters are adjusted by using the zero pole cancellation and the pole assignment method to achieve the goal of DC voltage stability.The sinusoidal pulse width modulation(SPWM)method is used to realize the flexible customization of power disturbance waveform.The experimental results show that the device runs smoothly after grid connected operation,and the stable output of power disturbance waveform is realized.
