The paper expounds the topology of TCR type SVC and proposes the controller’s implementation. Based on instantaneous reactive power theory, the paper ascertains the overall algorithm on SVC reactive power compensation. It can be refined to three steps: the extraction of active component and reactive component of fundamental, the modeling of compensation susceptances required and the four components of fundamental, and the establishing relationship of the fundamental equivalent susceptance of TCR and the triggering angle.The control performance of the algorithm is valued on accuracy and real-time.

Rotor Cage

For three-phase induction machines supplied by sinusoidal current, it is usual to model the n-bar squirrel-cage by an equivalent two-phase circuit. For a multiphase induction machine which can be supplied with different harmonics of current, the reduced-order model of the rotor must be more carefully chosen in order to predict the pulsations of torque. The proposed analysis allows to avoid a wrong design with non-sinusoidal magnetomotive forces. An analytical approach is proposed and confirmed by Finite-Element modelling at first for a three-phase induction machine and secondly for a five-phase induction machine.
