DEVELOPMENT OF BUCK CONVERTER BASED FUZZY LOGIC CONTROL IN SMALL SCALE WIND TURBINE SYSTEM IMPLEMENTED IN EAST-JAVA

Energy production from the wind turbines in order to function at its optimum should be controlled. Electrical power products generated turbine depends on the wind speed variations in wind lading. Voltage power products with varied, so before it was used or stored energy in the battery voltage level must be maintained. In this study constructed buck converter power electronics in the form of a fuzzy logic -based voltage control in wind turbines. Buck converter is a type converter lossless transition is relatively large compared to linear converter type. This process is carried out at voltage stabilization. Sugenp type fuzzy logic works with input error and delta error, the value of output in the form of crips for generating a signal pulse width modulation (PWM ). Performance of the fuzzy logic -based converter has been built to function properly. With HSIL indication that the test has been done. With the value of the turbine generator V setpoint input 2 volts, the measuring error of 0.8 %. At the advanced test with 4 volt V setpoint input has an error of 1.3 %, for V input with setpoint 6 volt has an error 0.5 % and the setpoint input V 8 volts produces kesalhan 0:22 %
