What is reactive power compensation?

Reactive power is an inherent part of the ”total power. … Reactive power compensation in power systems can be either shunt or series. Shunt Reactive Power Compensation: Since most loads are inductive and consume lagging reactive power, the compensation required is usually supplied by leading reactive power.

What is reactive power in electrical system?

The portion of electricity that establishes and sustains the electric and magnetic fields of alternating-current equipment. Reactive power is provided by generators, synchronous condensers, or electrostatic equipment such as capacitors and directly influences electric system voltage. …

What is the meaning of compensation in power system?

Definition: Series compensation is the method of improving the system voltage by connecting a capacitor in series with the transmission line. In other words, in series compensation, reactive power is inserted in series with the transmission line for improving the impedance of the system.

What is reactive power control?

Reactive power production and consumption by generators allows the network operator to control voltages throughout their system. Alternatively, the wind farm may have to adjust its reactive power consumption or production in order to control the voltage to a set point. …

How is reactive power compensated?

Increased utilization of equipment

Reactive power compensation in a power system is of two types—shunt and series. Shunt compensation can be installed near the load, in a distribution substation, along the distribution feeder, or in a transmission substation.

What is series compensation?

Series compensation is the method of improving the system voltage by connecting a capacitor in series with the transmission line. In series compensation, reactive power is inserted in series with the transmission line for improving the impedance of the system. It improves the power transfer capability of the line.
