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, thereby stabilizing the system voltage within acceptable limits. [1] The utility of shunt reactors for voltage control on lightly-loaded transmission lines was examined in a 1926 paper presented at the AIEE by Edith Clarke . [ 2 ]
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]
Fixed, shunt capacitor and reactor banks filled this need by being deployed where needed. In particular, shunt capacitors switched by circuit breakers provided an effective means to managing varying reactive power requirements due to changing loads. [3] However, this was not without limitations.
A magnetically-controlled shunt reactor (MCSR, CSR) represents electrotechnical equipment purposed for compensation of reactive power and stabilization of voltage level in high voltage (HV) electric networks rated for voltage classes 36 – 750 kV. MCSR is shunt-type static device with smooth regulation by means of inductive reactance.

Using the Smith chart, the normalised impedance may be obtained with appreciable accuracy by plotting the point representing the reflection coefficient treating the Smith chart as a polar diagram and then reading its value directly using the characteristic Smith chart scaling. This technique is a graphical alternative to substituting the values ...
Perceptual control theory has not been widely accepted in mainstream psychology, but has been effectively used in a considerable range of domains [57] [58] in human factors, [59] clinical psychology, and psychotherapy (the "Method of Levels"), it is the basis for a considerable body of research in sociology, [60] and it has formed the ...
