This paper presents an implementation of pseudo linear enhanced phased-locked loop control algorithm in three-leg Voltage Source Converter (VSC)-based Distribution Static Compensator (DSTATCOM) in three-wire power distribution system. This control algorithm is used for withdrawal of load fundamental active and reactive power components of distorted load currents for estimation of reference source currents. The PWM signals for the VSC based DSTATCOM are derived from the estimated reference source currents. The proposed control algorithm is implemented for mitigating multiple power quality issues such as load unbalancing, reactive power and current. The performance of the DSTATCOM is found satisfactory with the proposed control algorithm under non linear load. The dc bus voltage of the VSC of DSTATCOM has a negligible effect on varying loads.
