Magnetically controlled shunt reactor

[1] Magnetically-controlled shunt reactors are intended for automatic control over reactive power and stabilization of voltage levels; these ensure the following: On the assumption of tasks to be solved by MCSRs, as well as with consideration of existing experience of their operation, application field of controlled reactors covers (but not limited) the following areas of the power networks: Ample opportunities of MCSRs ensure expediency of their application for different voltage classes.

In the context of building-up of the market relations in the electric energy sector and increase of investments for development of power networks, MCSRs offer the complete series of considerable benefits for all economic entities:

To increase reactor load as for reactive power, its operating range should be offset to non-linear area of hysteresis characteristic; and this is achieved for the account of additional biasing of magnetic system.

In case of energy input to or output from the control circuit, the transient process of increase or decrease of network current and, respectively, of reactive power consumed by reactor is ensured.

Moreover, considering the additional measures and the control algorithms, MCSR realizes all functions of uncontrolled shunt reactor including ability to operate within the interval of single-phase automatic reclosing.
