| 摘 要： | 在变压器经济运行过程中存在着空载合闸的现象，而在随机关合空载变压器的时候会产生幅值很大的励磁涌流，可能导致继电保护装置误动作，降低电能质量。针对此种情况，提出一种变压器软启动控制策略来有效减小励磁涌流，并基于PSCAD/EMTDC搭建的变压器空载合闸仿真模型，通过仿真算例分析，验证了变压器软启动控制策略的可行性和有效性。

| Abstract: | There is a no-load switching phenomenon in the process of economic operation of transformers,and it will produce large amplitude of the inrush current when circuit breakers randomly close no-load transformer, and it may lead to relay protection device malfunction and reduce electric energy quality. This paper presents a soft start method,and it can effectively reduce the inrush current in transformer no-load closing. it builds the model of the transformer transformer no-load switching through PSCAD simulation software,and through the a-nalysis of simulation results,it can verify the feasibility and effectiveness of this control strategy. |
