As clean energy that solves energy resources, many wind turbine generator systems have developed up to now, in Japan. The generation capacity of wind power is above 1 million kW, and the construction also continues from now on. The wind turbine generator systems are built in the good place of the wind condition, and those many are built on the coast of the Japan Sea. However, the coast of the Japan Sea is known as a place with much winter lightning, and wind turbine generator systems also often suffer the damage by winter lightning. The authors observed the lightning current that strikes through the wind turbine generator systems directly, in order to establish on the lightning protection of them.<br>The authors acquired dozens of data as a result of observation in Akita Japan for 17 months. Based on these data, some considerations were performed about the performance of winter lightning that struck through the wind turbine generator systems. As the result of consideration, we found some interesting knowledge following sentence. It made clear anew that the tower which is a place of high position from the ground and on the windward has much number of lightning flash and many total flash charges. The lightning stroke current divided the tower pipe and ground leads. About 70% of the observed lightning current flowed to the tower pipe, and about 30% is divided into two grounding leads connected to the leg of tower. All of steep current that is on a wave front flow a tower side, it dose not flow to a grounding leads side. The distributions of lightning parameters between our observation results and past one are in good conformity.
