Study On The Control Strategy Of The Flexible HVDC Transmission System For Wind Power Generation System

China has a vast territory, which is rich in wind energy resources. Because of its clean and renewable and other characteristics, which is becoming more and more popular. Based on the constraints of transmission technology, the small scale wind farms. However, with the wind power generation technology is exquisite, the continuous expansion of the scale of wind farm, the site distance away, how to realize the long distance and large-scale electric power transmission become our concern. Flexible DC transmission technology because of its easy to control, can realize the power transmission over long distances, so more and more attention. In this paper, the application of flexible HVDC technology in wind power are analyzed.This paper first briefly introduces the basic principle of permanent magnet generator, wind turbine and its mathematics model. Established the mathematical model of permanent magnet synchronous rotating coordinates in the DQ direct drive wind power generation system based on rotor field oriented, technology, construction of permanent magnet generator active power, reactive power decoupling control strategy; grid voltage vector orientation technique based on the construction of the power transmission system, active power, reactive power decoupling control strategy. Methods using tip speed ratio to achieve the maximum wind energy tracking of.This paper first briefly introduces the basic principle of permanent magnet generator, wind turbine and its mathematics model.
