1·The main contents and aims of lightning stroke assessment are discussed.
对雷击风险评估的主要内容和目的进行了探讨。
2·In this paper the model of wind turbines is established and the transient overvoltage caused by lightning stroke is calculated and analyzed.
该文建立了相关的风电机组模型，对雷击引起的暂态过电压进行了计算分析。
3·The principal cause of lightning stroke failures occurred in UHV transmission lines is the shielding failure, so it is suggested to adopt the negative protecting Angle for UHVDC transmission lines.
引起特高压输电线路雷击故障的主要因素是雷电绕击，建议特高压输电线路采用负保护角运行。
4·The sensitivity of the proposed protection scheme is not impacted by the factors such as transition resistance, lightning stroke, fault type, load current and operating mode of power system.
该保护方案的灵敏度不受过渡电阻、雷击、故障类型、负荷电流、系统运行方式等因素的影响。
5·The calculated synthetic indexes of forest combustibility are 395 and 423, that build a fire for lightning stroke according with practical situation;
计算的森林可燃性的综合指标为395、423，表明应是雷击起火，与实际情况相符。
