A Novel Approach for Design and Analysis of Voltage-Controlled DSTATCOM for Power Quality Enhancement

Syed Ruman, Shaik Hameed

The power fluctuations affect the quality of power supplied by the distributed power system. The Power quality fluctuations of the distributed power system show a serious impact on the robust and sustainable operation of the distributed power system. These power quality fluctuations may be caused due to several reasons like leakage, faults and ageing of the lines. This project proposes a new algorithm to generate reference voltage for a controlled mode distribution static compensator (DSTATCOM) operating in voltage-control mode. The proposed scheme exhibits several advantages compared to traditional voltage-controlled DSTATCOM where the reference voltage is arbitrarily taken as 1.0 p. u. The proposed scheme ensures that unity power factor (UPF) is achieved, while regulating the voltage at the load terminal, during load change, which is not possible in the traditional method. Also, the compensator injects lower currents and, therefore, reduces losses in the feeder and voltage-source inverter. Further, a saving in the rating of DSTATCOM is achieved to increases its capacity to mitigate voltage sag. The state-space model of DSTATCOM is incorporated with the deadbeat predictive controller for fast load voltage regulation during voltage disturbances. With these features, this scheme allows DSTATCOM to tackle power-quality issues by providing power factor correction, harmonic elimination, load balancing, and voltage regulation based on the load requirement. Simulation and experimental results are presented to demonstrate the efficacy of the proposed algorithm.
