What does STATCOM stand for?
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.
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. In a STATCOM the speed of response is limited by the commutation frequency of the IGBT’s (normally 1 kHz).
What is STATCOM in electrical?
A static synchronous compensator (STATCOM), also known as a static synchronous condenser (STATCON), is a regulating device used on alternating current electricity transmission networks. If connected to a source of power it can also provide active AC power. It is a member of the FACTS family of devices.
What is the function of STATCOM?
The Static Synchronous Compensator (STATCOM) is used in an HVDC system to provide reactive power compensation. It makes use of the Voltage Source Converter (VSC) to synthesize a controllable sinusoidal voltage at the fundamental frequency.
Which type of controller is STATCOM?
Static Synchronous Compensator (STATCOM) is a Shunt active FACTS controller when connected at the mid point of the transmission line, it can improve voltage regulation, power flow and stability of the transmission systems.
What type of device are SVC and STATCOM?
SVC (Static Var Compensator) and STATCOM (Static Synchronous Compensator) are shunt devices in the FACTS family. The initial of the two, SVC, based on high power thyristor technology, appeared in the field in the 1970s.
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 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 is the function of a STATCOM Mcq?
It is a FACTS controller used for reactive power compensation. It maintains the voltage profile. Explanation: The full form of STATCOM is a Static synchronous compensator. It is a voltage source converter.
What is a STATCOM explain its construction and working?
STATCOM or Static Synchronous Compensator is a shunt device, which uses force-commutated power electronics (i.e. GTO, IGBT) to control power flow and improve transient stability on electrical power networks. It is also a member of the so-called Flexible AC Transmission System (FACTS) devices.
What is the importance of VI characteristics of STATCOM?
The characteristic of a STATCOM reveals another strength of this technology: that it is capable of yielding the full output of capacitive generation almost independently of the system voltage (constant-current output at lower voltages).
