Estratégias de energização e desenergização de um compensador estático síncrono para distribuição

Abstract

This paper proposes two controllers toenergize and de-energize static synchronous compensatorsto be connected to distribution networks. The firstcircuit is based on a semi-controlled rectifier while thesecond controller is based on AC voltage controller. Thetwo proposed controllers are easily adapted to the staticcompensator structure without the need of any topologicalchanges. A mathematical model is used to derive therelationships used to control the energizing and de-energizing currents. Piecewise linear approximations areused to reduce the computational effort of the developedcontrol algorithms. Simulation and experimental resultsare presented to validate the proposed methodology.
