风力发电场升压站作为风电场的重要组成部分，因为风电场所处位置一般较为恶劣，易遭受雷电波入侵，给设备和人身带来一系列的威胁。首先结合一风电场升压站遭受雷击的案例，对雷电流泄放前及泄放中两个时间段内，地网及地表的瞬态电位差进行仿真计算，然后分析和考察地网导体的瞬态电位分布对直接连接在水平地网上的一次设备、二次设备或二次系统的绝缘和干扰的影响，以及地表电位分布对人员安全的影响，并提供相应的防护建议。

Wind power plant booster station is an important component of the wind farm. Due to the location of wind farms in general is relatively poor, it is vulnerable to the thunder electric wave, and will bring a series of threats to equipment and personal safety. Combined with a case that a wind power plant booster station is struck by lightning, the transient potential difference of the earth's surface and the ground net before and in the process of lightning discharge flow are simulated and calculated. The influence of transient potential distribution of the ground net conductor on the interference and insulation of the primary equipment and secondary equipment or the secondary system that are directly connected with the level-ground grids and the influence of the surface potential distribution on the personnel safety are also shown. Some protective suggestions are given as well.
