What is a STATCOM system?
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. It is categorised under Flexible AC transmission system (FACTS) devices.
What are the components of STATCOM?
Components of a STATCOM STATCOM is basically comprised of four major components, namely • Voltage source converter (VSC) • Coupling transformer • Controller • DC energy storage. Voltage profile improvement is a very important aspect of power quality and system stability.
What is the role of STATCOM in power system?
The STATCOM provides voltage regulation at its connection point by controlling the reactive power absorbed from or injected into the power system through the VSC.
How is STATCOM connected in system?
The two areas are connected by two parallel connected long transmission lines. The direction of real power flow is from area-1 to area-2. The STATCOM is placed on one of the transmission lines and near to the generator being analyzed (area-1). Two-area system with STATCOM device.
Why do we need 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. A STATCOM is a voltage source converter (VSC) based device, with the voltage source behind a reactor.
What is STATCOM in HVDC?
A Static Synchronous Compensator (STATCOM) is a typical Flexible AC Transmission System (FACTS) device playing a vital role as a stability aid for small and large transient disturbances in an interconnected power 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.
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 is a STATCOM explain its construction and working?
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). PRINCIPLE OF OPERATION. Ø A STATCOM is a controlled reactive-power source.
What are the salient 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,
Which type of controller is STATCOM?
A long transmission line needs controllable series as well as shunt compensation for power flow control and voltage regulation. This can be achieved by suitable combination of passive elements and active FACTS controllers.
