一种改进型的虚拟同步发电机控制策略
A Modified Strategy of Virtual Synchronous Generator
摘要
Abstract
Built micro grid inverter based on virtual synchronous generator(VSG),made the inverter have the synchronous generator characteristics of large inertia,large output impedance. On the basis of the traditional droop control,proposed adaptive control and constant voltage constant frequency control to ensure the reliable operation of the island load mode. Proposed forecasts synchronization unit based on virtual impact current,that could finish grid phase tracking effectively before connecting to grid,greatly reduced grid instantaneous current shock.Analyzed simple static stability after connected to grid by microvariations method,so as to select appropriate parameters,such as inertia,damping,tuning value,ensured the VSG send active and reactive power followed instructions.关键词
