# 提高风电机组风能转化效率的变速控制技术研究Study to Improve the Wind Energy Conversion Efficiency with the Variable Speed Control

Abstract:
Based on the generation principle and power optimizing control principle of VSCF(variable speed constant frequency) doubly-fed wind turbine, this paper built the DFIG wind turbine, PWM converter, fuzzy variable speed controller, and other part of simulation models with software PSCAD. In the accordance with maximum power tracking principle of doubly-fed wind turbine, the converter control mode of generator side and the fuzzy control algorithm is brought in. On the basis of the fuzzy control principle, the design of the controller is completed in PSCAD. The effectiveness and feasibility of the designed method which is based on fuzzy control are demonstrated in the simulation results. It is proved that the wind energy conversion efficiency is increased by 0.1 with the variable speed control of optimization fuzzy.
