摘要
变压器非全相运行时将会严重危及变压器与电网的安全。针对一起110kV变压器非全相运行事故,运用对称分量法对变压器非全相运行状态进行全面分析,得出变压器三侧电压幅值、相位关系,并通过建立仿真模型,对分析结果进行仿真论证。根据计算、仿真结果对不同接线方式的变压器非全相运行状态进行分析论述,总结主变压器各种非全相运行的特征。
Transformer open phase operation is a serious threat to the security of transformer and power grid. An open phase operation of an 110kV transformer accident is analyzed based on the symmetrical components method and relationships of voltage magnitude and phase among three sides of the transformer are obtained. The simulation model is built to simulate the analysis result. According to calculation and simulation results, the open phase operation status of different connection type transformers are analyzed and discussed and characteristics of every open phase operation are summarized.
