Simulation on the Dash Currents of Paralleling Small Single Phase Synchronous Generators

The controller of paralleling small single phase synchronous generators(SSPSG) should restrict the dash currents in generators below defined value when switch on. This article has built the field-circuit coupling time-stepping finite element model of the parallel system. The computation program is written in APDL languages of ANSYS and the transient process of paralleling two SSPSGs in various parallel parameters are studied. The value and variation of the dash currents in two generators when switch on at various difference of three parallel parameters are analyzed and the accurate parallel parameters differences are provided to the parallel controller.
