The Research And Implementation Of Inverter Using In Stand-alone Wind Power Generation System

With issuing of renewable energy law , the industry of wind power generation has being developed fast, in 2006, increasing in wind installed capacity of our country is the fifth in world, and the total installed capacity is the sixth, wind installed capacity in the world has reached 74223 WM. Wind power generation belong to renewable energy generation technology, it is one of renewable energy generation technology which is supported by government, and it is very important for the Sustainable development of our nation. Stand-along wind generation system is one of the key methods to resolve people who live right out in the countryside of problem of electricity. The main content in this paper is:1. System adopts technology of high frequency inverting, its input voltage is DC48V, and output is standard commercial power, the characteristic of this system small volume, high efficiency and dependability.2. System takes the technology of SPWM and digital PID and implements the control of voltage.
