This paper presents the use of pulse-width modulated voltage source converter (PWM-VSC) for power quality improvement of a wound field synchronous generator-based diesel generator (DG) set realising standalone supply system. The system consists of a diesel engine driven wound field synchronous generator, a three-leg PWM-VSC with a capacitor on the DC link and linear/non-linear loads. The PWM-VSC supplies the leading kilo volt-amphere reactive (kVAR) to the loads and maintains the unity power factor of the DG set. In addition, it eliminates the harmonics from the source currents and provides load balancing. The terminal voltage is controlled by field excitation control of the generator and the supply frequency is controlled by the speed regulating system of the diesel engine. A variable step size filter-x least mean square-based control algorithm is used for estimation of reference currents for control of VSC.
