This paper reviews different technology used in reactive power compensation such as synchronous condenser, static VAR compensator, capacitor bank, series compensator and shunt reactor, comparison between them, source of reactive power and different optimization techniques.
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.
Reactive power compensation is commonly addressed as a constrained single-objective optimization problem [1-3]. Traditionally, it basically consists in determining an adequate location and size of shunt and/or series capacitor and reactor banks.
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.
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.
Capacitor provides reactive impedance that causes proportional voltage to the line current when it is series connected to the line. The compensation voltage is changed regarding to the transmission angle δ and line current. The delivered power P S is a function of the series compensation degree s where it is given by
