Abstract: This article built the field-circuit coupling time-stepping finite element model of the parallel system. The computation program was written in APDL languages of Ansys and the transient process of paralleling two single phase generators in various parallel parameters were studied. The value and variation of the dash currents in two generators when switch on at various differences of three parallel parameters were analyzed and the accurate parallel parameters differences were provided to the parallel controller.
Key words: single phase synchronous generator; parallel; dash current; simulation
