Design optimal in electrical power-permanent magnet synchronous generator of small scale wind turbine using fuzzy logic control

This article describes a prototype wind turbine is equipped with a system of fuzzy logic controllers (FLC), a technique of testing done to see the performance of wind turbines and wind turbine evaluation when we get a load or interruption of the changes that are fluktuativ wind speed and wind turbines produce angular velocity change so that turn lead generator fluktuativ. In this paper, a wind turbine is developed for the low rated wind speed in Nganjuk, East Java, Indonesia. Based on the characteristic of power coefficient of the wind turbine and the data profile of wind speed for the last three years, the pitch angle position was determined. It is shown that the wind turbine has its maximum power coefficient. This situation resulted in the production of electrical energy fluktuativ from wind turbines, electric power production skibstnys not be utilized directly to the load electrical equipment or stored on bateray. To meet the power quality, then the production of electric power that has an electric voltage value fluktuativ must be processed, then the buck converter built a device capable of converting electrical voltage level is called. Obtained from testing a stable output voltage, input voltage fluktuativ though. From prototype testing, the system is able to regulate the input DC voltage is varied, (14-28) v to the output voltage level that is designed (13.5 ± 0.15) volt.
