A traditional shunt reactor has a fixed rating and is either connected to the power line all the time or switched in and out depending on the load. Recently [1] variable shunt reactors (VSRs) have been developed and introduced on the market. The rating of a VSR can be changed in steps: the maximum regulation range depends on the capability of ...
Shunt reactors are used in power systems to counteract the effect of the line parasitic capacitance, ... A controlled shunt reactor (CSR) is a variable inductance ...
Typically, an SVC comprises one or more banks of fixed or switched shunt capacitors or reactors, of which at least one bank is switched by thyristors. Elements which may be used to make an SVC typically include: Thyristor-controlled reactor (TCR), where the reactor may be air- or iron-cored; Thyristor-switched capacitor (TSC) Harmonic filter(s)
The goal shunt compensation is to connect a device in parallel with the system that will improve voltage and enable larger power flow. This is traditionally done using shunt capacitors and inductors (reactors), [13] much like Power Factor Correction. The most common shunt compensation device is the Static VAR Compensator (SVC). [14]
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.
An adjustable-rate mortgage — commonly called an ARM — is a type of home loan with a variable rate. Unlike a fixed-rate mortgage, which locks in an interest rate and predictable payments that ...
The shunt capacitors are almost always provided with tuning reactors and, where necessary, damping resistors so that they can perform a dual role as harmonic filters. VSCs, on the other hand, can either produce or consume reactive power on demand, with the result that usually no separate shunt capacitors are needed (other than those required ...
Some troops leave the battlefield injured. Others return from war with mental wounds. Yet many of the 2 million Iraq and Afghanistan veterans suffer from a condition the Defense Department refuses to acknowledge: Moral injury.
