单相同步发电机并列冲击电流仿真研究

Simulation on Dash Currents of Paralleling Single Phase Synchronous Generators

通过建立单相同步发电机并列系统的场路耦合时步有限元模型,研究了两台单相同步发电机在不同并列参数差值下并列的暂态过程,得出在三个并列参数差值单因素及多因素作用下合闸后冲击电流的大小和变化规律,为单相同步发电机并列控制器设计提供了准确的并列参数差值整定依据。

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.
