Paper Details

The STATCOM (Static synchronous compensator) is a shunt connected voltage source converter usingself-commutating device and can be effectively used for reactive power control. This paper describes the modeling ofSTATCOM in which linear controller of current and voltage is replaced by IRP (Instantaneous reactive power)controller. The IRP p-q theory is based on the Clarke transformation.IRP theory consumes time of operation, it reducesharmonic distortion and improves power factor. The IRP theory for the control of the VSC (Voltage Source Converter) inthe STATCOM. It takes a feed back of the grid voltage and source current for the compensation of the lagging powerfactor. The static device used is ultra capacitor with controlled DC link voltage VSC. IRP controller allows an increasein transfer of apparent power through a transmission line and much better stability by the adjustment of parameters thatgovern the power system. The designed controller with variation of DC link voltage has been applied to the STATCOMand suitable DC link voltage has been selected on basis of spike and overshoot of response. The total design and analysisis carried out in MATLAB Simulink Software with complete graphical representation.
