多间隙避雷器截波特性对雷电侵入波过电压的影响

Dianci bileiqi
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，

风电机组混凝土桩基接地散流特性与结构优化研究

Dianci bileiqi
良好的接地装置是维持风电机组安全运行的关键，为研究风电机组混凝土桩基接地散流特性及降阻效率问题，本文利用COMSOL Multiphysics仿真软件搭建风电机组混凝土桩基模型，研究混凝土电阻率以及土壤条件对桩基散流特性、土壤击穿特性的影响，并提出柔性石墨复合接地材料外敷的结构优化措施。研究结果表明：桩基接地电阻随着混凝土（土壤）电阻率的增大而增大；相较混凝土电阻率，土壤电阻率对桩基散流特性的影响更明显；桩基周围土壤的火花击穿体积随混凝土（土壤）电阻率的增大而增大，而土壤电阻率对其影响更大 ...
