Wind power generation as a new energy is increasingly attraction interest and quickly development in recent years. The system of low speed PM generator direct driven by wind turbine which pares with the conventional wind power plants the generator is coupled with the turbine via a gearbox, does not have to maintain frequently, structure simple, electricity generation efficiency high, the overall cost relative is low. In the countryside and the remote districts the wind power generation is good application prospect. The main work of the thesis is as follow. This paper mainly studies the system of low speed PM generator direct driven by wind turbine. In theoretically, according to the wind power generation system mathematical model, the dynamic performance of the power generation system for different operation modes is simulated based on Matlab/Simulink. The output of the system of PM generator direct driven by wind turbine is variable voltage and variable frequency power. To get constant voltage and constant frequency energy that users need, the software and hardware of the inverter control system is designed. The inverter controller is adopted PIC singlechipputer and PWM chip SA4828, and IPM as inverter, LC wave filter. The voltage feedback is got through the chip AD736 which acplishes the task of sampling the voltage. To realize the reliable operation the wind power generation system, the software and hardware of the pitch and yaw control system designed. The controller uses PIC singlechip puter as central controller, which operates the system through measuring the wind speed, rotational speed, battery voltage and the charging current, etc. At the same time in order to strengthen the antiinterference performance of the controller, the input and output are isolated by the photoelectricity. 沈陽(yáng)工業(yè)大學(xué)碩士學(xué)位論文 2 The paper introduces the system simulation and software and hardware design in detail, and produces the simulation and the test result.
