This paper presents the load compensation by diesel generator. In this compensation reactive power, harmonics and unbalanced load current generates because of linear or non - linear loads. The control of Distribution Static Synchronous Compensator (DSTATCOM ) is used for reactive power, harmonics and unbalanced load current compensation. Proportional – Integral (PI) controller is used to maintain a constant voltage at the dc – bus of a voltage – source converter (VSC) working as a DSTATCOM. Switching of Three Level VSC is achieved by controlling load current using Sinusoidal P ulse W idth M odulation (SPWM) control. This scheme is simulated under MATLAB environment using simulink toolboxes for feeding linear and nonlinear loads. The modeling is performed for a th ree – phase, three – wire star – connected synchronous generator coupled to a diesel engine, along with the three level inverter based VSC working as a DSTATCOM
