What is the function of a static var compensator?

1 Static Var compensator. Static Var compensator (SVC) is a type of FACTS device, used for shunt compensation to maintain bus voltage magnitude. SVC regulates bus voltage to compensate continuously the change of reactive power loading.

What are the main components of static var compensator?

SVC includes two main components and their combination: Thyristor-controlled and Thyristor-switched Reactor (TCR and TSR); and Thyristor-switched capacitor (TSC).

What are the types of static var compensator?

Types of SVC

Thyristor controlled Reactor.
Thyristor switched capacitor.
Thyristor Switched Reactor.
Thyristor controlled Transformer.

What are the advantages and disadvantages of static var compensator?

Advantages and Disadvantages As the device has no revolutionary parts, for the implementation of surge impedance compensation, additional equipment is needed. The size of the device is heavy. Deliberate dynamic response.

What are the types of passive compensation?

The reactive-power control for a line is often called reactive-power compensation and external devices or subsystems that control reactive power on transmission lines are known as “compensators”.

Why VAR compensation is usually required?

One of these is the necessity of reactive power that needs to be supplied along with active power. It is economical to supply this reactive power closer to the load in the distribution system. Reactive power compensation in power systems can be either shunt or series.

What are the objectives of series compensation?

The main purpose of series compensation in power systems is to decrease the reactive impedance of the transmission line to reduce voltage drop over long distances and to reduce the Ferranti effect.

What are the specifications of load compensation?

Load compensation is the management of reactive power to improve power quality i.e. V profile and pf. Here the reactive power flow is controlled by installing shunt compensating devices (capacitors/reactors) at the load end bringing about proper balance between generated and consumed reactive power.

What is difference between series and shunt compensation?

The main difference between the SVC and STATCON is that in case of SVC the current injected into the system depends upon the system voltage, but in case of STATCON it is independent of system voltage. STATCON generate or absorb reactive power without the use of capacitor or reactors.

What are the different methods of VAR compensation?

There are different technologies for reactive power compensation, these includes; Capacitor Bank, Series Compensator, Shunt Reactor, Static VAR Compensator (SVC), Static Synchronous Compensator (STATCOM), and Synchronous Condenser.

What are the objectives of shunt compensation?

The ultimate objective of applying reactive shunt compensation in a transmission system is to increase the transmittable power. This may be required to improve the steady-state transmission characteristics as well as the stability of the system.
