隔离开关动作过程特快速暂态电磁干扰变化特征及变化规律分析

Gaoya dianqi
隔离开关开合操作时产生的特快速暂态过电压/过电流可能会严重威胁电网的可靠性，但目前尚缺乏对隔离开关特快速暂态过程的电磁干扰变化特征及变化规律的研究。文中以隔离开关分合容性小电流试验的暂态电压、电流数据为基础，提取了对应的宏脉冲波形和单脉冲波形的特征数据，通过概率密度函数拟合以及样本累积经验分布的KS检验对暂态波形特征数据进行了全面的统计分析。结果表明，分、合闸操作的宏波形持续时间概率密度分别服从GEV、inverse Gaussian分布；VFTO、VFTC单脉冲的最大峰值分别为50 kV、370 A ...
