Reactive power compensation is an important aspect in the control of distribution systems. Reactive current in addition to increasing the distribution system losses, introduces various power quality problems like, harmonics, voltage sag, swell and poor load power factor. These power quality issues result in the malfunction of sensitive equipments. A Distribution Static Compensator (DSTATCOM) proves to be a viable solution for the mitigation of power quality problems. It provides effective compensation to linear varying/nonlinear loads by injecting appropriate reactive power at the point of common coupling (PCC). It exhibits the behavior of an active power filter and that of a voltage regulator. The choice of proper current control strategy is an important aspect in DSTATCOM performance. This paper compares linear and nonlinear methods of current regulation pertaining to DSTATCOM performance operating under Synchronous Reference Frame (SRF). The paper briefly describes the salient features of each regulation method with its merits and demerits. A dynamic model of a DSTATCOM has been developed using the two control techniques in MATLAB/SimPowerSystems environment to observe their performances and comparison. |
