In the past, rotating synchronous condensers and fixed or mechanically switched inductors or capacitors have been used for reactive power compensation. Today, static Var generators employ thyristor-switched capacitors and thyristor-controlled reactors to provide reactive power compensation.
The static VAR compensator (SVC) is the shunt compensation method which is used to compensate the reactive power. The SVC uses Thyristor Controlled Reactor (TCR) /Thyristor Switched Capacitor (TSC) control method by the help of which reactive power is either absorbed or generated. To control the SVC a triggering alpha is used.
Reactive power is either generated or consumed in almost every component of the system. Reactive power compensation is defined as the management of reactive power to improve the performance of AC systems. Why reactive power compensation is required? 1. To maintain the voltage profile 2. To reduce the equipment loading 3. To reduce the losses 4.
There are different technologies for reactive power compensation, these includes; Capacitor Bank, Series Compensator, Shunt Reactor, Static Var Compensator (SVC), Static Synchronous Compensator (STATCOM), and Synchronous Condenser.
Thus, the main case that should be handled in reactive power compensation by using STATCOM is to control the magnitude of compensator voltage VI. This operation is performed based on two basic principles where one is used in multi-pulse converters and the other one for PWM controlled multilevel converters.
The reactive power compensation and voltage control is primarily performed by selecting shunt devices that are shown in the first line of the figure. The SVCs are capable to present more accurate and smoother control comparing to mechanically switched shunt compensators.
