Customer ServiceShunt reactors are widely deployed as effective compensation means against the capacitive behavior of high voltage transmission lines. Subsequent to load rejection or light load conditions, a resonance phenomenon is highly potent due to remarkable capacitive feature of these lines.
The difference between the reactor and supply side voltages is called the Transient Recovery Voltage (TRV). Both sides of the switch start at the crest voltage of the power system, but due to the high frequency of the Shunt reactor, its voltage rapidly departs from the system voltage creating a steep and high magnitude TRV.
Shunt reactors, primarily switched in during periods of low demand, provide the necessary compensation by absorbing the excess reactive power. The main function of shunt reactor is reactive power compensation. Series reactors on the other hand are used to limit short-circuit currents and manage power flow.
Shunt reactors carry small currents, typically 300 A or less. It is relatively easy to interrupt small currents at first. When the current extinguishes, the shunt reactor voltage oscillates toward zero at the reactor natural frequency, typically 1 to 5 kHz. The supply side varies at 60 Hz power frequency.
One of the common cases which raise the probability of the resonance phenomenon in the grid is a double-circuit line compensated with a shunt reactor. Shunt reactors are usually used on high voltage transmission lines to limit overvoltages during the line energization, load rejection, and under light load conditions.
This voltage rise is caused on lines by Ferranti rise1 and capacitive rise2 when they are lightly loaded3. For this reason, shunt reactors are normally connected to the line (not the bus). Ferranti rise is an effect where a lightly loaded transmission line has a higher voltage at the distant end than the source end.
