Saturated Reactor

Saturation reactors are also known as "saturation chokes". A kind of reactor consisting of AC winding, DC winding, and one or more silicon steel sheet cores. The AC winding is connected in series with the load of the main circuit of the control system, and the DC winding is connected to the DC control current. Changing the magnitude of the control current can change the saturation degree of the core and change the reactance value.

Application: Due to the high hysteresis and expansion noise of SR, it is often installed in a thickly wrapped place. In addition to protective spark gaps and load tap switch switches, saturation reactors are a very reliable device and are therefore typically used in:

(1) Large offset of control voltage;

(2) Mitigating voltage flicker;

(3) Reactive power compensation at the DC transmission terminal.

The SR-type compensator has built-in voltage control capability, which directly responds to changes in the voltage at the terminal without the need for thyristor switching or external control to regulate the voltage. When applied to ultra-high voltage systems, SR-type compensators are connected to the transmission system bus via a coupling transformer. Since the SR-type compensator adopts an iron core structure, it has the inherent ability to withstand 3∽4PU overcurrent, which makes it very suitable for controlling short-term overvoltage. However, the overload capability of the SR may be limited by the slope correction capacitor, and although it is possible to bypass the slope correction capacitor with a spark gap in severe overvoltages, this comes at the expense of overvoltage regulation characteristics.

The saturation reactor of the slope correction capacitor is the fastest of all commercial SVCs, and the slope correction capacitor slows down the response, with a total response time of 1.5∽2 cycles, which is comparable to that of thyristor-controlled reactors (TCRs). SR losses are greater compared to TSC.
