Abstract

This paper presents the compensation of reactive power, harmonics, and unbalanced load current of diesel generator set for an isolated system by controlling voltage source convertor (VSC) which is working as distribution static synchronous compensator (DSTATCOM). Here least mean square based adaptive linear element (ADALINE) is use to extract balanced positive sequence real fundamental frequency component of the load current for converter and used to control DSTATCOM. For fast dynamic response and to maintain constant voltage at dc bus of DSTATCOM, a proportional integral (PI) controller is used. Voltage source converter switching signals are obtained by using modulation technique called hysteresis based pulse width modulation (PWM). The simulation model is simulated in MATLAB by using PSB and SIMULINK tool boxes to compensate DG set which feeds both linear and nonlinear loads. PI controller is replaced by fuzzy controller to reduce total harmonic distortion (THD) and steady state error. Results will discuss the comparison of PI and fuzzy controller of DSTATCOM and verify the optimal operation of DG set and the effectiveness of both controllers for DSTATCOM.
