提出了一个三相Yo/Yo/y-12-12(即星形/星形/星形-12-12)电力自耦变压器的实时仿真模型,给出了有效的数字积分方法,对该变压器空载合闸涌流的电磁暂态过程及负载运行过程进行了仿真.仿真实例在PC机系统上的运行结果表明,所提出的模型和选用的数字积分方法是正确的.

This paper presents a real-time simulation model of a three-phase star/star/star-12-12 power auto-transformer and its numerical integration method. In addition, the authors have also simulated the electromagnetic transients of the inrush phenomenon when the transformer is switched in the null-loaded circuits as well as the process of the normal-loaded state. The simulation result on the PC shows that the model and the numerical integration method are correct and can be realized in real time.
