Research on Grid-Connected Strategy of Virtual Synchronous Generator Based on Fuzzy Control
摘要
Abstract
Based on the control of three-phase inverter based on virtual synchronous generator,the double loop control system was composed of capacitor voltage and current feedback.Among them,the current loop and voltage loop were proportional integral control.However,the traditional double loop control had such shortcomings as low precision and slow response speed,The whole fuzzy control system had the function of adjusting the parameters according to the nonlinear system error of the system.On the basis of this,a control strategy of virtual synchronous motor based on the combination of double loop control and fuzzy PI was proposed.A detailed analysis of the fuzzy parameters after loop control setting,effectiveness and the method was proved by simulation research.关键词
