非线性负载下虚拟同步发电机的控制策略
Control Strategy for the Nonlinear Load of Virtual Synchronous Generator
摘要
Abstract
The principle of the output voltage distortion caused by the nonlinear load of the virtual synchronous generator was analyzed. Integrated control strategy of harmonic voltage suppression using PI+Quasi PR was proposed. The series of notch filter was designed for the separation of different frequency of components of the PPC voltage,and the fundamental components were controlled by the virtual synchronous generator controller. At the same time,a Quasi-PR controller was adopted for suppressing the harmonic components,and the harmonic content of PCC point voltage was reduced. The feasibility of the strategy was verified by simulation and experiment.关键词
