Reactive power control in power system
WebIn the case that the reactive power has to be controlled, a reactive power reference must be imposed to the system. Linear PI controller is an established reference tracking technique associated with the d-q control structure due their satisfactory combinational performance. Eq. (8) states the transfer function on the d-q coordinate structure. WebSTATCOM or Static Synchronous Compensator is a power electronic device using force commutated devices like IGBT, GTO etc. to control the reactive power flow through a power network and thereby increasing the stability of power network. STATCOM is a shunt FACTS controller i.e. it is connected in shunt with the line.
