Application of Dstatcom for Load Compensation of Isolated Diesel Generator System

This paper deals harmonics, reactive power and unbalanced load current compensation of a Diesel Generator set for an isolated system using the control of Distribution Static Synchronous Compensator (DSTATCOM). Least Mean Square Based Adaptive Linear Element (ADALINE) method is used for the control of DSTATCOM. In order to extract balanced positive sequence real fundamental frequency component of the load current an ADALINE is used and in order to maintain a constant voltage at the dc-bus of a voltage-source converter (VSC) and to obtain a fast dynamic response a proportional-integral (PI) controller is used and are working as a DSTATCOM. Switching of Voltage Source Converter is achieved by using hysteresis-based Pulse Width Modulation (PWM) control. This scheme is simulated using MATLAB/SIMULINK for linear, nonlinear and Brushless DC (BLDC) motor loads. Results are given to verify the effectiveness of the control of DSTATCOM for the load compensation of the DG-SET.
