It consists of a power capacitor connected in series with a bidirectional thyristor valve and, usually, a current limiting reactor . The thyristor switched capacitor is an important component of a Static VAR Compensator (SVC), [ 1 ] [ 2 ] where it is often used in conjunction with a thyristor controlled reactor (TCR).
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. It is a member of the FACTS family of devices.
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.
Many circuits can be analyzed as a combination of series and parallel circuits, along with other configurations. In a series circuit, the current that flows through each of the components is the same, and the voltage across the circuit is the sum of the individual voltage drops across each component. [1]
One type of series compensation is the Thyristor-Controlled Series Capacitor (TCSC), which combines the TCR from an SVC in parallel with a traditional fixed series capacitor. As using power electronics to switch capacitors sub-cycle is not feasible due to concerns of stored charge, a TCR is used to create a variable inductance to offset the ...
Static synchronous series compensator. A static synchronous series compensator (SSSC) is a type of flexible AC transmission system which consists of a solid-state voltage source inverter coupled with a transformer that is connected in series with a transmission line. This device can inject an almost sinusoidal voltage in series with
A switched capacitor (SC) is an electronic circuit that implements a function by moving charges into and out of capacitors when electronic switches are opened and closed. . Usually, non-overlapping clock signals are used to control the switches, so that not all switches are closed simulta
Switching circuit theory is the mathematical study of the properties of networks of idealized switches. Such networks may be strictly combinational logic, in which their output state is only a function of the present state of their inputs; or may also contain sequential elements, where the present state depends on the present state and past states; in that sense, sequential circuits are said ...
