摘要:
风电场通常建设于雷电活动较为频繁的地区,其集电线路容易遭受雷击,对风电机组及其配套设备的安全构成严重威胁。本文采用电磁暂态软件程序ATP-EMTP分别建立了雷电流模型、杆塔模型、集电线路模型、绝缘子模型和避雷器模型用于模拟雷电击中集电线路杆塔的情况,研究了线路过电压的影响因素,并提出了相应的防护措施。结果表明:雷电击中杆塔的位置和杆塔的接地电阻是集电线路过电压的主要影响因素; 对于山区的风电机组,可采用阶梯式降低靠近风机侧杆塔的接地电阻和在靠近风机侧杆塔上安装避雷器这两种防护措施对风电场内集电线路进行防雷。
Abstract:
Wind farms are usually built in areas with frequent lightning activities, so their collection lines are vulnerable to lightning strikes, which posing a serious threat to the safe operation of wind turbines and their supporting equipment. Based on the electromagnetic transient program ATP-EMTP, the lightning current model, the tower model, the collection line model, insulator model and arrester model were established, which were used to simulate lightning sets to the tower of collection lines. The influence factors of line overvoltage were studied and the corresponding protective measures were analyzed. The results show that the position of the lightning bolt and the grounding resistance of the tower are the main factors affecting the overvoltage of the collection line. For wind turbines of mountainous area, the lighting protection of collection line can be achieved by reducing the grounding resistance of tower near the wind turbine and installing arrester at the tower near wind turbine.
