Research on the Field Strength Calculation of Super High Voltage Transmission Lines

超高压输电线路具有电压高,电场强度大的特性,对周围环境有很大的影响。本文在分析输电线路典型传输模型的基础上,根据麦克斯韦方程组及边界条件,利用模拟电荷法和模拟电荷法-矩量法计算出输电线路的空间工频场强分布,最后在仿真环境中进行试验。实验结果表明,利用该方法可以有效的模拟出输电线路周围空间中的场强分布。

The super high voltage transmission line has the characteristic of high voltage and high electric field strength, which has a great influence on the surrounding environment. Based on the analysis of the typical transmission line model, according to the Maxwell equations and boundary conditions, calculate the spatial distribution of power frequency electric field of transmission lines using the charge simulation method and charge simulation method, method of moments, the fi- nal test in the simulation environment. The experimental results show that the method can effectively simulate the distri- bution of the field intensity in the surrounding space of the transmission line.
