虚拟同步发电机的相角控制方法
Phase angle control method of Virtual Synchronous Generator
摘要
Abstract
Virtual synchronous generator ( VSG ) technology simulates the characteristics of the synchronous generator by power conversion system (PCS). Thus, the converter will have the characteristics of the synchronous generator such as primary frequency regulation, primary voltage regulation, damping and inertia. So the voltage and frequency regulation ability of converter for power grid will be enhanced. It can also help to improve the friendliness of grid-connection. In this paper, a new rectification method for phase angle and frequency of VSG based on phase locked loop (PLL) is proposed. The unreasonable deviation of frequency and phase is corrected in the process of starting grid connection and in the condition of strong disturbance, to reduce the oscillation and out-of-control risk under the above conditions. Finally, some experimental tests are given for correctness verification of the proposed method.关键词
