| 摘 要： | 小型单相同步发电机并列控制器设计时,并列参数选择需要限制合闸后冲击电流不大于一定范围。通过建立小型单相同步发电机并列系统的场路耦合时步有限元模型,并采用ANSYS的APDL语言编制的计算软件,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3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条件。

| Abstract: | The controller of paralleling small single phase synchronous generators should restrict the dash currents in generators below a defined value when it switches on. A field-circuit coupling time-stepping finite element model of the parallel system is built. The computation program is written in APDL languages of ANSYS and the transient process of paralleling two single phase synchronous generators in various parallel parameters are studied. The value and variation of the dash currents in two generators when switch on at various differences of three parallel parameters are analyzed and the accurate parallel conditions are provided to the parallel controller. |
