Dynamics of hybrid high voltage commutator with separately controlled phases

Abstract

The paper considers application of hybrid circuit-breaker with separately controlled phase contacts used to shut phase-to-ground fault in electric network with insulated neutral. Concept of hybrid commutator comprising thyristor commutator and circuit-breaker with separately controlled contacts is discussed. Elaborated algorithm and program to investigate transients of the linear induction drive of circuit-breaker and results of simulation are discussed.
