Intellegent lightning monitoring system for wind turbine generator

With the increase of both unit capacity of wind turbines and size of wind farm, the safe operation of wind farm has received growing attention. In many factors that affect the safe operation of wind farms, being struck by lightning is an important aspect. The intelligent lightning monitoring system is used for smart surveillance of wind turbine generators, which can have real-time and accurate monitoring of the lightning current waveforms, amplitude, time of occurrence, number of lightning strokes and all the other important parameters of lightning thus providing an effective monitoring and analysis tool to quickly locate faulty location on wind turbine generator and cause of the malfunction and a theoretical basis for the design of lightning protection system of wind turbines. This paper examines the principle and main methods of the wind turbine generator-matching lightning monitoring system, and combined with the specific research projects, designs and implements a high-precision and multifunctional intelligent lightning monitoring system based on the theory of Rogowski coils.
