Three-element Reactor-Capaсitor Device for Flexible Link Between Non-Synchronous Power Systems

Abstract

Short review of known variants of flexible controlled interconnections between asynсron power systems was fulfilled. The basic characteristics of three-element reactor-capacitor device, providing controlled power transmission and reactive power internal balance for connected power systems with different levels of voltages, were investigated. Mathematical model was elaborated for calculation of parameters of reactor-capacitor device elements, necessary for realization of circular rotation of output voltage phase angle at fixed load admittance. These results allow estimating the required range of the admittances changing, necessary to ensure control of transmitted power by means of semiconductor switching devices.
