摘　　要：动态电压恢复器是解决电压跌落的最有效装置。为了提高装置的响应速度和稳态精度,提出一种新的综合控制策略,详细分析了控制器的数学模型。基于同步坐标变换法在前馈控制和反馈控制的基础上,设计了两种控制方法共同作用的综合控制,建立数学模型,通过Simulink搭建仿真模型。仿真结果表明这种控制方法提高了系统的阻尼特性,完善了电压补偿效果,装置具有很好的控制稳定性,信号补偿的准确性,响应时间的快速性。仿真证明了该方法的有效性和可行性。具有实际研究意义。Dynamic voltage restorer is the most effective solution for voltage drop. In order to improve the response speed and steady-state precision of the device, the paper analyzed the mathematical model of controller in detail. According to the synchronous coordinate transformation method which base on feed forward control and feedback control. And design the comprehensive control method which based on the two control methods. Established mathematical model and build simulation model through Simulink. The simulation results show that this control method improved the damping characteristics of the system, perfect the voltage compensation effect, and the device has the very good control stability and the accuracy of the signal compensation and the rapidity of response time. The simulation proved the feasibility and effectiveness of the method. And have practical significance.
