兆瓦级风力发电机组防雷电保护

风电系统中涉及的过电压保护及防雷接地问题较多，但我国还没有风电系统过电压保护和防雷接地的国家标准或行业标准，为了促进风电行业的快速发展，本文简单介绍了雷电的形成过程及雷电的几种入侵形式，系统地阐述了目前国内兆瓦级风电机组的防雷方案设计及其实现，满足了工程的实际需要，对风力发电和风电场设计具有较好的指导意义。

Lightning Protection of Mega Watt Wind Turbines

Although the problems concerned with the overvoltage protection and lightning protection in the wind power generation system are complicated, there is no state or industrial standard related to this field. To accelerate the development of the wind power industry, this article briefly introduces the formation process for the lightning and how many types of this lightning. This article also systematically explains a lightning protection concept and how to put this concept into practice. This article will play a guiding role in designing the wind power generation system and wind farm.
