Control and Modification of 12-Pulse Static Compensator with PV Cell Using New Control Algorithm

الملخص

In this paper proposed a new controller design to modify pulses for power injection to the system by using photovoltaic(PV) connected directly with static compensator (STATCOM). The new proposed controller can control the 12-pulse STATCOM and control the angle between the injection current, source voltage and maintain the load current at appropriate level. Two close loops control has been proposed in this work. dq controller and phase locked loop (PLL) with proportional integration(PI) controller are employed to control the performance of the angle between the source voltage and load voltage at 1 p.u. In this design the response of the load voltage is follow the source voltage angle. The control system was modeled by using PSCAD software package.
