How does STATCOM control reactive power?
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. Generally, STATCOM is connected near the loads at distribution system. 1 shows block diagram of STATCOM placed in transmission system.
Which compensator is used for both active and reactive power control?
7.3 The static synchronous compensator (STATCOM) The STATCOM is a shunt-connected FACTS device that is used primarily for reactive power control. The STATCOM has two possible steady-state operating modes: inductive (lagging) and capacitive (leading). STATCOMs have been widely accepted to improve power system operation.
In which mode the STATCOM absorbs reactive power?
Again, if the voltage of power system increase due to load throw off, STATCOM will reduce its output voltage V1 and therefore will absorb reactive power to stabilize the voltage to normal value. The above mode of operation of STATCOM is called Voltage Regulation Mode.
What is the difference between STATCOM and Dstatcom?
DSTATCOM is Distribution Static synchronous shunt compensator which is used at distribution level for real and reactive power compensation, ESTATCOM is Energy storage Equipped Static synchronous Compensator which is actually a STATCOM used for Energy Storage.
What is hybrid compensator?
A Hybrid Var Compensator is a power electronics-based device connected in parallel with the load that requires harmonics mitigation. At the same time, they can filter out the harmonics of the system, reduce voltage variations, mitigate flicker and balance the loads.
How is STATCOM connected in the 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.
What is STATCOM operation?
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 is SVC and Statcom?
Abstract: Both SVC (Static Var Compensator) and STATCOM (Static Synchronous Compensator) are important equipment of reactive compensation, which are compared in voltage supporting, improving the transient stability and transmission limit, and damping low frequency oscillation.
