Development of Megawatt Wind Turbine Based on Codesys Variable Pitch PID Controller

摘要

The paper mainly studies the control strategy of megawatt wind-power generator variable pitch control system. Based on the comparisons between the incomplete total differential PID control-algorithm-developing controller and the traditional PI controller through building mathematical models, an optimized variable pitch control strategy is put forward. By running the actual fan program to conduct full wind speed simulation through Codesys programming software that is commonly used in engineering application, the optimized control algorithm has advantages of small overshoot, high precision in control and smooth output angle after comparison, which can provide design ideas and solutions for the optimization of variable propeller pitch control system strategy.
