What are the features of STATCOM?

Key features of STATCOM System include:

  • Usually connected to High Voltage (HV) grid via a step down power transformer.
  • Always a symmetrical power rating in the inductive and capacitive operating regions.
  • Hybrid solutions available for increased power rating including: STATCOM, plus.
  • Thyristor Switched Components,

What is importance of VI characteristics of STATCOM?

STATCOM V-I Characteristic The STATCOM can be operated in two different modes: In voltage regulation mode (the voltage is regulated within limits as explained below) In var control mode (the STATCOM reactive power output is kept constant)

What is the purpose of STATCOM?

A STATic synchronous COMpensator (STATCOM) is a fast-acting device capable of providing or absorbing reactive current and thereby regulating the voltage at the point of connection to a power grid.

On what principle a STATCOM can work?

A STATCOM is a controlled reactive-power source. It provides the desired reactive-power generation and absorption entirely by means of electronic processing of the voltage and current waveforms in a voltage-source converter (VSC).

What are the advantages of STATCOM?

STATCOM has superior performance in lots of aspect such as responding speed, stabilize voltage of power grid, reduce system power loss and harmonics, increase both transmission capacity and limit for transient voltage. It also has advantage of smaller in dimension.

What are the characteristics of SVC?

The SVC regulates voltage at its terminals by controlling the amount of reactive power injected into or absorbed from the power system. When system voltage is low, the SVC generates reactive power (SVC capacitive). When system voltage is high, it absorbs reactive power (SVC inductive).

Why is STATCOM used in load flow?

Static Synchronous Compensator (STATCOM) It converts the dc input voltage into ac output voltages to compensate theactive and reactive power of the system. STATCOM has better characteristics than SVC andit is used for voltage control and reactive power compensation.

What are the functions of STATCOM in the improvement of power system performance area?

The stability plays an important role to ensure the stable operation of power system in the occurrence of large disturbances and faults. The role of STATCOM will be mitigate the voltage problem like voltage sag, voltage swell which are generally occurs in power system during high voltage and low voltage condition.

What are the common advantages of STATCOM?

What are the advantages over STATCOM over synchronous condenser?

Simulation results show that the synchronous condenser can effectively improve sta- bility of the power system even without reactive power injection, while STATCOM only enhances system strength through reactive power compensation.

What is the difference between STATCOM and SVC?

The main difference between a STATCOM and an SVC is the way they operate: a STATCOM works as a controllable voltage source while an SVC works as a dynamically controllable reactance connected in parallel.

What are the advantages of SVC?

The main advantage of SVCs over simple mechanically switched compensation schemes is their near-instantaneous response to changes in the system voltage. For this reason they are often operated at close to their zero-point in order to maximize the reactive power correction they can rapidly provide when required.
