Abstract

In this work a three phase three wire Distribution Static Compensator (DSTATCOM) is proposed for power quality improvement. DSTATCOM is based on a three leg VSC and is controlled to compensate reactive power, harmonic current and unbalances in the load. IGBT based VSC is capacitor supported and is controlled for the required compensation of the load current. The control algorithm extracts reference currents and generates gate pulses for IGBT switches by PWM technique. For reference current calculation, two types of control algorithms are proposed. One is based on Synchronous Reference Frame Theory (SRFT) and the other on Adaline (Adaptive Linear Element) based neural network. DC bus controller regulates the dc bus voltage under varying load conditions. Performance of three phase three wire system with DSTATCOM is validated for harmonic elimination and balancing of loads by using simulation model in MATLAB /SIMULINK.
