Study on Intelligent Control of Three Phase Grid-connected Inverter of Wind Power Generation
In the networking operation of wind power generation, grid-connected inverter is important for energy conversion and transmission. But the output current with harmonic component is increased due to the inverters low switching frequency of P WM signal. In order to reduce the harmonic current of grid connected inverter, hybrid filter is used in the design of the grid-connected inverter in this article.An electrical model of grid-connected inverter with hybrid filter was built, and then a control strategy based on the intelligent theorem proposed,in which an adaptive PID controller using BP neural network of intelligent theorem was adopted to control the output current of the grid-connected inverter.The results of simulation are given and confirm that the novel control strategy based on the proposed adaptive PID intelligent theorem could get a good control effect for the output current of the grid-connected inverter.
