Research on Inverter Control Technique for off grid Wind Power Generation System

摘要

The paper studied the typical off grid wind power generation system. And then, the paper researched on the control strategy of the single phase inverter, especially studied the PID control and double closed-loop control. At last, the paper simulated the control effect of PID control and double closed-loop control with MATLAB software. In particular, the double closed-loop control system has been tested again and again to obtain a set of ideal parameters. In order to simulate the sudden increase and decrease of user load in power generation system, we suddenly add the disturbance in the simulation system. The results show that the double closed-loop control system has better steady precision and has strong robustness to load disturbance.
