The task of additional reactive power compensation (also known as voltage compensation) is assigned to compensating devices: [7] passive (either permanently connected or switched) sinks of reactive power (e.g., shunt reactors that are similar to transformers in construction, with a single winding and iron core [ 9 ] ).
In Electrical Engineering , a static synchronous compensator (STATCOM) is a shunt-connected, reactive compensation device used on transmission networks. It uses power electronics to form a voltage-source converter that can act as either a source or sink of reactive AC power to an electricity network.
A unified power flow controller (UPFC) is an electrical device for providing fast-acting reactive power compensation on high-voltage electricity transmission networks. It uses a pair of three-phase controllable bridges to produce current that is injected into a transmission line using a series transformer. [ 1 ]
In Electrical Engineering, a static VAR compensator (SVC) is a set of electrical devices for providing fast-acting reactive power on high-voltage electricity transmission networks. [1] [2] SVCs are part of the flexible AC transmission system [3] [4] device family, regulating voltage, power factor, harmonics and stabilizing the system. A static ...
On light loads, the power drawn by induction motors has a large reactive component and the power factor has a low value. The added current flowing to supply reactive power creates additional losses in the power system. In an industrial plant, synchronous motors can be used to supply some of the reactive power required by induction motors.
The FACTs family initially grew out of the development of High-Voltage Direct-Current (HVDC) conversion and transmission, which used Power Electronics to convert AC to DC to enable large, controllable power transfers. [1] While HVDC focused on conversion to DC, FACTs devices used the developed technology to control power and voltage on the AC ...
