研究开发了一种输电线路杆塔雷电感应过电压数字仿真软件,该软件可用于计算雷击杆塔时感应过电压的幅值及波形,使得在防雷计算中,感应分量可以简单、合理地与注入分量进行波形叠加,进而求得更为准确的雷电过电压。改进了目前直接将两者的峰值电压进行叠加的方法。分别采用CoorayRubinatein方程计算得到的结果和工程实测结果对本仿真软件进行了验证,最终证明本仿真软件所得结果与实测数据具有很好的吻合度。
A digital simulation software for lightning induced overvoltage of transmission line tower is developed and developed. The software can be used to calculate the amplitude and waveform of induced overvoltage when lightning strikes the tower, so that in the lightning protection calculation, the induced component can be easily and reasonably connected with the injected component Waveform superimposed, and then find a more accurate lightning over-voltage. At present, the method of directly superposing the peak voltages of both is improved. The simulation software is verified by the CoorayRubinatein equation and the measured results respectively. Finally, the simulation results show that the simulation results are in good agreement with the measured data.
