摘要
文章简单介绍了变压器运行原理,在理论基础上,运用Matlab/Simulink中电气系统模块库中的仿真模型,对常见的双绕组三相变压器在空载合闸过程中产生励磁涌流的工况进行仿真建模,并通过模型获得了空载合闸时电流电压变化曲线及其变化规律,研究结果对提高变压器运行的可靠性、减少事故发生率具有一定的指导意义.
In this paper, the principle and mechanism of transformer operation are briefly introduced. On the basis of theory, the simulation model of electrical system module library in Matlab/Simulink is used. In this paper, the simulation modeling of the excitation inrush current produced by the common double-winding three-phase transformer in the process of no-load closing is carried out, and the current and voltage variation curve and its variation law during no-load closing are obtained through the model. The research results have certain guiding significance to improve the reliability of transformer operation and reduce the incidence of accidents.
