Transformers with voltage regulation for electric supply networks
Abstract
Power transformers for electric supply networks in which the necessary voltage regulation and compensation of reactive power are effected through switching of the magnetic flux by superconducting shields are described. The performance characteristics, including the shielding action, are analyzed for appropriate equivalent circuit diagrams and the corresponding system of Kirchhoff equations. Voltages and currents are calculated by matrix notation. With the shield impedance ratio Z sub sh/jwL sub sh variable from 0 to oo, the transformer input impedance and output voltage is regulated simultaneously.
