摘要
在介绍电力变压器励磁涌流产生的机理和内部故障产生原因的基础上,论述了使用电磁暂态程序EMTP软件进行电力变压器励磁涌流仿真和内部故障仿真的方法。详细论述了借助BCTRAN变压器模型生成的变压器绕组感抗矩阵R-ωL对变压器励磁涌流和内部故障进行仿真的过程,并给出仿真结果。结果表明,电磁暂态程序EMTP能够有效地对变压器励磁涌流和绕组内部故障进行仿真计算。此研究过程得到的仿真数据将用于后续的信号分析和神经网络技术应用等研究工作。
This paper introduces the mechanism of inrush of transformer and internal fault. Based on this, simulation methods of inrush of transformer and internal fault with EMTP are described in detail. According to the transformer mutually coupled R-ωL generated by BCTRAN transformer model, the simulation procedure of inrush and internal fault is introduced step by step, and all the simulation results are given in graphical way. The results show, inrush and internal fault can be simulated effectively with EMTP. All the results obtained from this research will be used in the followed signal analysis research and application research of neural network technology.
