ABSTRACT:The problems of energy and environment must be solved in human survival and development, the energy we used in our daily life is given mostly with coal, oil and natural gas. But they are non-renewable energy, and caused a serious of air pollutions. We pay high attention to the development and utilization of renewable energy for its great importance to all over the country. Globally, wind power has become a mature technology. Variable propeller control is one of the key technologies of today's large wind turbines. This design scheme does research into wind power control system. Programmed and controlled mainly by the FX2N series PLC to control system. The pitch system is the speed of the generator to control the pitch drive motor is the blade pitch angle is changed, so as to obtain the required by the generator speed, stable output power of the generator. It has the advantages of higher utilization rate for wind power, more stable output power, safe and reliable, and automated for variable pitch wind turbine.
