FIG.1 is a flow diagram of the lightning stroke protection method for the wind farm provided by the example of the present invention.
As shown in FIG.1, the examples of the present invention provide the lightning stroke protection method for the wind farm, including the following steps: 101: based on the lightning stroke transient calculation model of the wind farm collector system, the lightning over voltage characteristics and tripping related data of the collecting power line triggered by lightning stroke are determined.
In a specific implementation process, the lightning stroke transient state calculation model of the wind farm collector system is established by the procedure method, the collector system includes collecting power lines, box transformers and 35kV (10kV) high-voltage distribution devices. Through field research, the meteorological data, the geographical data and the environmental parameter of the wind farm are determined, the establishment of the final lightning stroke transient state calculation model of the wind farm collector system can more accurately calculate the lightning over voltage characteristics and tripping related data of the lightning triggered collector line.
Wherein, lightning over voltage characteristics includes lightning direct characteristics and lightning induction characteristics, etc,. The tripping related data includes the tripping reason and tripping position and tripping number and other data. 102: based on the lightning over voltage characteristics of the collecting power line, the lightning induction over voltage and the direct lighting over voltage are determined.
Then, based on the lightning over voltage characteristics of the collecting power line, the lightning induction over voltage and the direct lighting over voltage are determined respectively.
Wherein, the lighting induction over voltage refers to the voltage generated by electromagnetic induction in the process of lightning stroke, and the direct lightning voltage refers to the voltage generated directly by receiving lightning stroke.
The lightning induction over voltage is determined that can be calculated by using the principle of electromagnetic induction. The direct lightning voltage is calculated and that can be directly detected by voltage detection equipment. LUS05193 103: based on the lightning induction over voltage, the direct lightning over voltage and the lightning stroke transient state calculation model of the wind farm grounding system, the lightning stroke tripping ratio of the current wind farm is determined; 5 Specifically, it can determine the lightning electric current waveform, the tower height, the artificial grounding form, the connection relationship between the wind turbine, the box transformer, the first end tower of the collecting power line and the surge arrester grounding system are determined; based on the lightning electric current waveform, the tower height, the artificial grounding form, the connection relationship and the geometric structure of the wind farm reinforcement network, the lightning stroke transient state calculation model of the wind farm grounding system is constructed.
Through the development of on-site soil resistivity test measurement and the grounding resistance measurement, combined with the tower, the artificial grounding and the natural grounding factors, the effects of the lightning electric current waveform, the tower height and the artificial grounding form on the transient state characteristics of grounding system and collector system are calculated and analyzed, the effect of interconnection or independent mode between wind turbine, the box transformer, the first end tower of the collecting power line and the surge arrester grounding system are evaluated, finally, the lightning stroke transient state calculation model of the wind farm grounding system is constructed, it can ensure the accuracy of lightning tripping ratio calculation, therefore, the optimization of artificial grounding in high soil resistivity area and the suppression measures of counter attack over voltage are realized, the design of wind farm grounding grid and equipment selection are improved.

Specifically, the lightning over voltage analysis model of the lightning stroke blade, the lightning direct stroke line and the lightning strike near the ground can be established. Combined with the topographic parameters such as altitude and ground inclination of the high altitude wind farm collecting power line corridor, the electrical geometric model of the collecting power line is established. Considering the conditions of lightning activity intensity and soil resistivity in high altitude areas, the flash over ratio of shielding failure and back flash over ratio of each tower of the collecting power line are calculated, and then the series gap surge arrester protection device suitable for the integrated assembly of split integrated insulators for high altitude wind farm collecting power lines is constructed. LUS05193
