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
Fixed capacitor banks are an economical choice for individual inductive loads or a group of loads that has a relatively constant demand for reactive power. Examples of such loads are induction motors and transformers. This paper derives simple and compact expression for power of fixed capacitor bank for reactive power compensation
This paper derives simple and compact expression for power of fixed capacitor bank for reactive power compensation absorbed by transformer itself, at different load conditions. It is shown that the installation of capacitor bank whose power corresponds to rated load decreases the rms value of current
The reactive power compensation corresponds to the controlling of reactive power to increase the performance characteristics of the AC system. There are some methods by which the power factor of the system can be improved and hence these are regarded as methods of reactive power compensation.
The modal analysis method was used to find the optimal installation position for the reactive power compensation device. The improved particle swarm algorithm was used to optimize the capacity of the optimal reactive power compensation device to ensure the best performance of the compensation device.
As we know that the capacitor takes the leading reactive power, thus this causes the decrease in power taken from the source. This resultantly improves the value of the power factor of the system. This is further classified as series and shunt compensation. Suppose we have a circuit shown here,

Reactive power
In some cases, special circuits are used to measure the reactive power. For example, the reactive power measurement can be performed with compensation capacitors to determine the amount of reactive power compensation. Here, capacitors are added or removed to minimize the phase shift angle and thus compensate for the reactive power.
