Controlling of frequency fluctuation of wind turbine generator using wind speed controlled pitch controller

Abstract

Due to the growing electricity concern, it is very much needed to use wind power for the generation of electricity. But for the random variation of wind speed, the output power of the wind generator fluctuates randomly as well as the fluctuation of the frequency occurs. As a result this decreases the energy. This paper represents a wind speed controlled pitch controller to control the wind generator output power fluctuation and also reduce the frequency fluctuations. For simulation analysis, real wind speed data is used and the simulation analysis have been performed by using PSCAD/EMTDC [1].
