Summary:With the rapid development of new energy, more and more scholars have focused on the wind power industry, in which the safety of offshore wind farms with increasing demand has received extensive attention. Due to the special environment, the reliability requirements of offshore wind turbine are much higher than those of onshore wind turbine. Lightning stroke is an important factor affecting the safety of the wind farm and the working stability of the unit. In the process of lightning stroke, when the lightning current flows through the frame and tower, it will produce induced Overvoltage on the sensor, communication line and even power line. These transient overvoltage will affect the normal operation of the wind turbine. Combined with the lightning stroke characteristics of wind turbines and the technical means of lightning protection, this paper briefly introduces the current lightning protection technology of wind farms and wind turbines, and constructs a simplified model of offshore wind turbine integration by using ATP-EMTP simulation software. Mainly by studying the voltage of tower and transmission core, this paper studies the functions of common different lightning protection measures,it has guiding significance for practical engineering and production.
