摘要 在提出电压暂降作用下,考虑暂降电压波形起始点特征的交流接触器建模方法,用PSCAD/EMTDC仿真程序分析电压暂降过程中,暂降波形起始点对交流接触器响应特征的影响和接触器的电压暂降穿越能力。用交流接触器暂降穿越能力曲线识别交流接触器故障区域内的敏感度水平,利用建立的仿真模型对不同波形起始点特征的电压暂降进行了仿真,仿真结果证明提出的方法的正确性,对于准确评估电压暂降作用下的交流接触器的响应特性具有一定指导意义。 The modeling method of AC contactor considering starting point features of voltage sag waveform is presented. The influence of starting point of voltage sag waveform on response characteristics of AC contactor and its ride - through capability during voltage sag are analyzed with PSCAD/EMTDC simulation software. The ride - through capability curve is used to identify the sensitivity level in the fault area of AC contaetor. The simulation for voltage sag of starting point features of various waveforms is carried out by the established simulation model. The simulation results are also validated with the ride - through capability curve of the experimental results.
