Research and Modeling of Magnetically Controlled Shunt Reactors in PSCAD/EMTDC

Abstract

Magnetically controlled reactors (MCRs) as shunt reactors have offered flexible ways regulating the reactive power in the power system. The article provides an overview of various types of reactors. Compared, the design of the magnetic cores of the reactors, allowing to implement two different schemes for connecting the network winding, parallel counter and parallel consonant. The principle of half-period magnetization of saturation of sections of the magnetic circuit (half-limbs) on which the windings of the reactors are located is described. To clarify the parameters and develop proposals for the production of a pilot industrial design, an adequate mathematical model of the reactor was developed in the PSCAD software package. Preliminary calculations and comparative analysis showed that a controlled reactor with three-limb magnetic cores would be easier, with smaller dimensions and, therefore, cheaper.
