Design of fault simulation system for electric variable pitch based on wind power generation

Based on the structure of the variable pitch system of wind turbine,an experimental platform of the electric variable pitch fault system for the wind turbine is built,and the system structure,main circuits and experimental flow chart are presented.This experimental platform is composed of the fault input subsystem and fault output subsystem,and the electric variable pitch control process experiment and pitch control fault test experiment can be carried out,which enables students to fully understand the principle of pitch control,and to learn and research on the aspects such as the wind turbine power stable output,the wind speed causing wind turbine uneven load and the reduction of the pitch system failure rate.
