Design and Research of Wind Turbine Blade Lightning Wire Breaking Detection System

During the operation of wind turbine blade, it is affected by a series of extreme weather, such as lightning, which will directly damage two systems in the blade, one is the mechanical system, the other is the electrical system. Sometimes, it will lead to accidents such as explosion, shutdown for a certain time and loss of a lot of power generation. Therefore, in the wind turbine blade, it is necessary tocomprehensively detect the lightning conductor, which has great practical significance. Based on this, thispaper presents a test system, which combines the principle of traveling wave method and carries out corresponding processing for the obtained signal data through the use of multiple devices, such as signal generator and sensor. On this basis, the actual position of disconnection is determined. Through the experimental results, it can be seen that compared with Ohmic method, the system selects the optimized test device, which is light in weight, does not need to lift the device manually, and can accurately determine the wire breaking position, with an accuracy of no more than , which has outstanding technical advantages.
