Pitch Control of DFIG Wind Turbine Based on Fuzzy Logic Controller

T.Anil Kumar, Ch.V.V. Mangalakshmi


With improvement in variable speed system control and design of wind power system, the energy capture of these systems also rising. For enhance the efficiency and performance of wind energy conversion system(WECS),In this paper come up with Pitch angle control of a Doubly FED Induction Generator(DFIG) based wind power system with the objective of maintain constant power with variable wind speed by using fuzzy logic controller. This paper presents principal conversion of wind energy, wind turbine linearization and dynamic modeling are derived.  The fuzzy logic controller is employed for change blade angle of wind turbine and constant power can be achieve. The block diagram of proposed pitch control which consists of pitch controller, actuator model and turbine linearized modeled by using Matlab/Simulink software.
