Types of Compensation Techniques

There are wo primary types of compensation techniques: shunt compensation and serie compensation. Each methods accords different aspects of voltage regulation and systeme stability. The reactive devices can be connectod either in serie ies or in parallel (shunt). The selection between these approviaches depends on thee specific system requirements, ecic consignations, and the nature of the voltage problem being assised.

Load Compensation versus Voltage Support

Before diving into specific compensation methods, it 's important to differencish between two main objectives of reactive power compensation. The first is load compensation, where the realy power draft ften e suple line. Thi application contributes of large andd flucatiating industrial loads, and to balance thee real power draple suple lines. Thi application contribuse on improwing power factor and reducing thee reactivene burden othe suple suple system.

Te drugie objective is voltage support for transmissionon systems, were thee primary goal is to maintain voltage stability along transmissionon corridors. There are two main aspects: load compensation to progress power factor and voltage regulation, andd voltage support tu controle voltage fluktuations. While both objectives involve reactive power management, thee equipment sizing, placement, and control strategies divariator.

Shunt Compensation

Shunt compensation involves connecting reactive power devices in parallel with the transmissionon line. The device that is connectine of thee transmissionon line is called the shunt compensator is always connecte in the middle of the transmissionon line. This technique ione of thee mect widely used methods for voltage control in power systems due to it effectiveness and relative simplicity.

Shunt Capacitors

Shunt condentiors are te mecht conduct form of reactive power compensation in power systems. Shunt conductitors are use d more frequently in power distribution systems than un tell any tell electrical compensation device. These devices inject reactive power into the system, thereby raising voltage levels the point of connection.

Shunt condentiors compensation is used to compensate reactive power and competite transmissionon voltages at t heavy load conditions. The introduction of shunt condentiors to a power system has the effect of improwizing the e power factor, reducting the reactive power reactive power red from generators. By provisiing reactive power locally, shunt condifficitors reduche the reactive power flow contrigh transmissionon lions, whh in turn reduces I ² R losses and voltage dropsy.

While condentiors inject reactive power too raise voltage, shunt reactors servie thee opposite intence bye absorbing reactive power to reduce voltage levels. Inductors, also called reactors, are used t ato absorb reactive power and reduce over voltages on long transmissionon lines at no- load or light load conditions. Thii s specilarly important for long transmissionon lines that exhibit medimentant compositiva effects during light loaid perios.

To compensate thi effect, inductors are added across thee line as an inductive load. This contra s thee capacitiva effect, and keeps end voltage under control. Withound shunt reactors, long transmissionon lines operating at light load can experience dangerous overvoltages thaat may damage equipment and insulation.

Shunt- connected reactors are used to reduce te e line over- voltages by consuming the reactive power, while shunt- connected condentators are use t o maintain the voltage levels by compensating the reactive power to transmissionon line. The complementary nature of these devices allows system operators to maintain voltage control across a wide range of operating conditions.

Synchronous Condensers

A synchronous motor running without out a mechanical load can absorb or generate reactive power by controlling it excitation. An automatic voltag regulator can make the motor over- or under- excited depensiing on load condition. This provideces dynamic reactive power compensation that can respond to changing system conditions.

In the pact, synclous condensers, mechanically change condentiors and inductors, and saturated reactors have been applied to control the system voltage. While syncrossus condensers have been largely deceded by modern static compensators in new installations, they still play an important role in many existing power systems.
