What are the applications of STATCOM?

In the transmission system, STATCOM can be used to provide voltage and reactive power control, to enhance the system damping, to suppress low-frequency and sub-synchronous oscillation, and to improve power system transient stability.

Why do we use STATCOM?

Usually a STATCOM is installed to support electrical networks that have a poor power factor and often poor voltage regulation. The most common use of STATCOM is for voltage stability.

What is the main objective 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.

How does STATCOM compensate reactive power?

The STATCOM is connected as shunt device which is used for compensation. By using STATCOM, reactive power can be compensated by either absorbing or injecting. Voltage profile and power factor of the transmission system is also improved by using STATCOM. 1 shows block diagram of STATCOM placed in transmission system.

What is the function of a STATCOM Mcq?

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. 9.

What can be 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.

How does a STATCOM system work?

The function of a STATCOM system is to provide reactive compensation to the grid when it is needed most, during fault and transient conditions. GE’s STATCOM solution is the only commercial solution that uses a 7mF capacitor as its DC voltage source for stabilizing the grid, nearly 2 to 3 times larger than competing solutions.

What is Gege STATCOM system?

GE’s STATCOM utilizes highly dynamic VSC based compensators, which when compared to SVC solutions, provides improved range of operational voltage, with higher reactive output at lower system voltage and robust recovery support under severe system disturbances and provides a smaller footprint. Key features of STATCOM System include:

What is synchronous in STATCOM?

The terms Synchronous in STATCOM mean that it can either absorb or generate reactive power in synchronization with the demand to stabilize the voltage of the power network. To understand the working principle of STATCOM, we will first have a look at the reactive power transfer equation.

What is the voltage regulation capability of Statcom?

As can be seen, voltage regulation capability of STATCOM is from V1 (in lower side) to V2 in upper side of power system. If the voltage of power system goes below V1 or above V2, STATCOM acts in VAR Control mode.
