摘要
雷击是影响风力发电场运行安全的主要因素之一。在雷击过程中 ,雷电流沿塔筒注入风电场接地网 ,将会引起接地网的地电位升高。这些暂态过电压将对风力发电机组及其输变电设备的正常运行造成影响。通过建立相关的风电场接地网模型 。
Lightning is one of the important factors to affect the security of wind farm operation. When lightning happens, lightning current enters grounding systems through the tower, which will cause ground potential rises. These transient overvoltages can affect the normal operation of wind turbines and other power equipments. This paper develops a model of wind farm grounding systems, and calculates the transient overvoltages.
