The pure inductive loaded system and phasor diagram are illustrated in Fig. 8.3 referring to aforementioned approach. The pure inductive loads, i.e. shunt reactors used in tap-changing transformers and generation stations, do not draw power and δ between load voltage V and source voltage E is zero. Since the voltage drop jX S I is in phase between V and E, the

To maintain a power factor close to unity, the rating of different capacitor banks is dependent upon the analysis on the reactive power requirement. Based on demand analysis, this compensation requirement should be divided into fixed and variable parts. For a production plant, minimum load and thus minimum KVAr load can be calculated. And the remaining KVAr

One way to avoid reactive power charges, is to install power factor correction capacitors. Normally residential customers are charged only for the active power consumed in kilo-watt hours (kWhr) because nearly all residential and single phase power factor values are essentially the same due to power factor correction capacitors being built into most domestic appliances by the
The intuitive idea underlying the reactive power compensation process is the following one: to avoid the penalties that the electric utility imposes due to the consumption of reactive power (Q) by the R-L loads, the customer installs capacitor banks. In that way, the customer can produce the reactive power that his plant

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.
Instead of using capacitor banks, there is a different alternative to compensate the reactive power that is based on the use of synchronous compensators. These are synchronous machines that, operating with null active power, can behave either as variable capacitors or coils, by simply changing their excitation current .
Therefore, taking into consideration the basic Equation 1, we can conclude that, for a certain apparent power S, the higher the reactive power (Q) to be generated (in order to the supplied to the customers), the lower the active power (P) that the generator can produce. In other words, the generation of Q limits the capacity of generating P.
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 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 computer plays a vital role in all parts of life and industry, especially in the power system applications. The capacitor bank is considered as one method to improve the power factor (PF) and reduce the line current and since the equipment of the analysis cannot be provided always.
