【摘要】 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。更多还原

【Abstract】 A digital simulation software of lightning induced voltage is designed. The software can compute amplitude and waveform of induced voltage when pole-tower is strucked by lightning, improve current method which directly superimposes two peak voltages. Through the software computation, induced component is superimposed with injection component simply and rationally, one more exact lightning induced voltage is gained. The simulation software is verified with computation result of Cooray-Rubinatein equation and project actual result, and is integrated with project actual result.更多还原
