摘要
为了有效降低变压器在空载合闸瞬间产生的励磁涌流,本文通过对变压器一次侧串电阻、并联变压器两种预充磁技术进行了仿真分析。同时为了验证所得到的仿真结果是否可信,构建了仿真试验平台。最终证明了所得的仿真结果能够较好的反应实际系统,也说明了变压器在空载合闸时产生的励磁涌流,不但与所选择的预充磁变压器容量有关,还与预充磁变压器接入电网的合闸时间有关。
In order to reduce inrush current of the transformer during the transformer no-load switching,this paper adopts simulation technology to analyze methods of resistor in series before the transformer primary side and pre-magnetization of transformer in parallel. In order to validate the credibility of the simulation results, test platform is built. Finally, the results can be representation of the actual system, and show that the inrush current is related to the transformer capacity and the switching time of the pre-magnetized transformer connecting to the power.
