What are the methods of reactive power compensation?

What are the methods to compensate the reactive power?

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. Each application has different purposes.

What are the techniques for reactive power compensation in transmission line?

Since the real part of the power is 0, therefore the reactive power in the system is added by shunt compensator. Shunt-connected reactors are connected in the system to control the reactive power. By consuming the reactive power shunt connected reactors decrease the over voltages in the transmission line.

What is reactive compensation in power?

Reactive compensation is the process of adding or injecting positive and/or negative VAr’s to a power system to essentially attain voltage control.

What is shunt and series compensation?

In series compensation, the FACTS is connected in series with the power system. It works as a controllable voltage source. … To compensate, a shunt capacitor is connected which draws current leading the source voltage. The net result is improvement in power factor.

Which are the shunt compensation devices?

The static synchronous series compensator (SSSC) and thyristor-controlled series capacitor (TCSC) are some of the FACTS control devices which provide series compensation to reactance of the lines to which they are connected, while the static synchronous compensator (STATCOM) and static VAR compensator (SVC) (where VAR

Which method is used for reactive or voltage compensation?

Synchronous condensers—can be used to generate reactive power, when they are operated as a motor. Shunt capacitance —Capacitor banks can be connected in parallel to the transmission lines. Series capacitance —Capacitors connected in series, especially for long lines can be used to raise the voltage.

What is reactive power in wind turbine?

Reactive power production and consumption by generators allows the network operator to control voltages throughout their system. … The simplest is the fixed power factor. The wind farm is required to operate at a fixed power factor when generating, often equal to 1.

Do wind turbines consume reactive power?

Besides the shunt flexible alternating current transmission system (FACTS) devices such as the static var compensator (SVC) and the static synchronous compensator (STATCOM), the wind turbine itself can also provide a certain amount of reactive power compensation, depending on the wind speed and the active power control …

What are the major sources of reactive power?

Some of the dynamic sources which acts as sources to the reactive power are: Synchronous generators.

Reactive Power Sinks:

  • Induction motors(pumps, fans)
  • induction loads (Arc furnace, heaters)
  • Induction generators.
  • Synchronous machines (under excited)
  • Transmission lines heavily loaded.
  • Transformers.
  • Shunt reactors.
