基于HHT的1000kV输电线路等电位脉冲电流幅值与能量研究

Gaoya dianqi
带电作业是确保特高压输电线路安全稳定运行的关键技术，进出等电位脉冲电流幅值与能量特征是带电作业中确定电磁干扰特性的基础参数。为此现场实测1000 kV进出等电位脉冲电流，首先通过波形特征值提取算法统计电流特征量，分析转移电荷与作用积分和电流幅值的关系；然后基于HHT研究电流频域能量特征，探讨频率范围及能量强度。结果表明：峰值电流主要分布在[-500，500] A；上升时间、脉冲间隔、脉宽、转移电荷及作用积分的算术平均值分别为0.020 μs、1.72 ms、0.96 μs、1.45 mC、0.127 ...
