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.
To provide reactive VAr control in order to support the power supply system voltage and to filter the harmonic currents in accordance with Electricity Authority recommendations, which prescribe the permissible voltage fluctuations and harmonic distortions, reactive power (VAr) compensators are required.
HV Power Capacitors are designed to compensate inductive loading from devices like electric motors and transmission lines to make the load appear to be mostly resistive. GE's capacitor units are a simple, economical and reliable source of reactive power on electrical power systems to improve their performance, quality and efficiency.
Compensation 4.1 Introduction The term compensation is used to describe the intentional insertion of reactive power devices, capacitive or inductive, into a power network to achieve a desired effect. This may include improved voltage profiles, improved power factor, enhanced stability performance, and improved transmission capacity.
Damping reactors installed in capacitor banks limit the current transients to acceptable values for the capacitor units and reduce surge currents to acceptable values for the corresponding switching devices. The filter reactors are connected in series with the capacitor units to form a series resonant circuit with a very low impedance.
This may include improved voltage profiles, improved power factor, enhanced stability performance, and improved transmission capacity. The reactive devices are connected either in series or in parallel (shunt). Series capacitors are utilized to neutralize part of the inductive reactance of a power network.

Thus, a direct way of increasing power transfer in power transmission systems, and of reducing voltage drop, is to compensate part of the series inductive reactance by series capacitors. Series compensation reduces the series impedance of the line which causes voltage drop and is the most important factor in finding the maximum power transfer [3].
