风机附近的防雷问题是风电场防雷的重点,影响到风电资源能否安全有效送出。目前采用在集电塔后一基杆塔三相安装多间隙避雷器可以与氧化锌避雷器配合,减少由于避雷器故障而造成的系统故障,但是多间隙避雷器在动作时产生的截波沿线路传入风机箱变,可能会威胁到变压器绕组的绝缘。基于上述问题,本研究在ATP-EMTP上搭建了多间隙避雷器截波特性对风机箱变绕组的绝缘影响分析仿真模型,考虑了多间隙避雷器的常规安装方式和极限安装方式,分别计算了两种情况下多间隙避雷器在受雷击后产生的截波过电压对风机箱变绝缘产生的影响。通过仿真分析,

超高压输电线路架线位置高、架设回数多及输送距离远,其运行中容易受到雷电袭扰,从而威胁系统稳定性和可靠性,不同雷击类型会对线路不同部位产生损伤。针对雷击类型的准确识别问题,提出一种超高压线路雷击类型识别方法。以500 kV同塔双回路鼓型杆塔为例,在ATP-EMTP平台中建立了考虑多因素的仿真模型,分析不同故障工况下雷电绕击、反击的特征,以雷击线路后故障信号通过杆塔入地的暂态信号作为研究对象,提出一种基于改进希尔伯特黄变换的雷击类型识别方法,利用故障信号的固有模态函数(IMF ...
