ABSTRACT

With the rapid development of the global economy, the large consumption of traditional fossil energy by human beings has not only triggered a worldwide energy crisis. Wind energy, as a clean and renewable energy source, has certain stability. Powering the country through wind power In order to improve its power quality, it can effectively reduce the threat to the overall power grid during the grid connection process. This paper establishes a control model of wind power generation, builds a radiation topology, uses lead-acid battery energy storage, and uses two-way dc / dc conversion the generator is integrated into the DC network and adopts a permanent magnet direct-drive wind turbine. The variable-speed constant-frequency wind power system can control the speed of the wind turbine, so that cp can maintain a maximum value within a large range of wind speed changes, and achieve maximum power tracking control.
