| 摘 要： | 在电力系统动态数字实时仿真研究中,变压器模型应该被精确描述。文中提出了一个三相、双绕组、Y0/△-11电力变压器(由3个单相变压器组成)的数字实时仿真模型,对该变压器空载合闸的合闸涌流的电磁暂态过程及匝间短路故障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,并且能实时实现。

| Abstract: | Digital simulation model of power transformer is very important in the study of power system dynamic real-time digital simulation.This paper presents a real-time digital simulation model of a three-phase, double-winding, star/delta-11 power transformer. In addition, the author has also simulated the electromagnetic transient of the inrush phenomenon when the transformer is switched in the null-loaded circuits as well as the process of short-circuit fault between turns. The simulation result on the PC shows that the model and the numerical integration method are correct. |
