Study Of Small Wind Turbines Grid-Connected Inverter

Wind power is a kind of green energy it gains more attention and development in recent years. Wind power technologies, especially wind power inverter technology become the world's research focus. In the areas which rich in wind resources and have low voltage grid, the development of the use of small wind power can not only effectively improve the utilization of wind power, but also bring real economic benefits to the user. Therefore, is an inevitable trend of development. This paper research-the system of small-scale wind power grid-on, search a suitable topology for small-scale wind power grid-connected inverter.On this basis, given the system model, control strategy analysis simulation and DSP implementation. Main content:(1) Analysis and compare of the existing grid-on topology and design a topology for small wind power grid-on system. Given the calculation of main circuit parameters and the selection of major components(2) The system is divided into rectifier, boost, inverter three aspects and given detailed theoretical analysis to every aspect, also given the corresponding simulation model get satisfactory simulation results(3) Given detailed design and introduction for the four core algorithm which control the output current (prediction algorithm, digital PI algorithm, software lock algorithm and inverter control algorithm) and gives the DSP28335 resource allocation.(4) As additional, introduce the small wind power islands prevention and the impact on the current protection...
