What are the modes of operation of STATCOM?
The STATCOM has two possible steady-state operating modes: inductive (lagging) and capacitive (leading). STATCOMs have been widely accepted to improve power system operation. The STATCOM consists of a single VSC and its associated shunt-connected transformer.
What is STATCOM voltage?
A STATCOM is a voltage source converter (VSC)-based device, with the voltage source behind a reactor (STATCOM is connected to the utility grid via a transformer). The voltage source is created from a DC capacitor and therefore a STATCOM has very little active power capability.
What is the advantage of STATCOM over SVC?
STATCOM normally exhibit a faster response than SVC, because of the voltage source converter technology, that has no delays associated with the firing of its thyristors. Under distorted main voltage conditions STATCOM can provide more reactive power for keeping the voltage near referenced value.
What is the role of STATCOM in power 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.
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 are the functions of STATCOM in the improvement of power system performance area?
It can be concluded from the simulation results that the proposed STATCOM can be used to improve the performance of the voltage stability, transient stability, rotor angle deviation, transmission line to power grid under different operating conditions.
What is a STATCOM discuss 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.
