This study proposes a three-dimensional (3D) quasi-static modelling of the electric field produced by high voltage (HV) overhead power lines using charge simulation method combined with intelligent optimisation algorithms, such as particle swarm optimisation, genetic algorithm and grey Wolf optimiser (GWO), to find the optimal values of parameters for an accurate calculation. Results show that the GWO works better than other algorithms. Several parameters affecting the electric field have been studied; it is observed that taking into account the effect of the exact catenary curve of the power line conductors is much more interesting particularly at the mid-span level where the electric field becomes very significant. According to these values, the limits set by the International Commission on Non-Ionising Radiation Protection guidelines for electric field strength are met for occupational and public exposure. The simulation results are compared with those obtained by the 3D Integration method, a fairly good agreement is found. To confirm the performance and effectiveness of the proposed method, the results obtained are also verified with measurement values available in the literature, a good similarity is achieved.

高压优化架空线下电场的3D建模与仿真分析

这项研究提出了使用电荷模拟方法结合智能优化算法（例如粒子群优化，遗传算法和灰狼优化器）的高压（HV）架空电力线产生的电场的三维（3D）准静态建模（GWO），以找到参数的最佳值以进行精确计算。结果表明，GWO比其他算法更好。已经研究了影响电场的几个参数。可以看出，考虑到电力线导体的精确悬链曲线的影响尤其令人关注，特别是在电场非常显着的中跨水平。根据这些值，满足职业和公众暴露的国际非电离辐射防护委员会针对电场强度设定的限制。将仿真结果与通过3D集成方法获得的仿真结果进行比较，发现相当不错的一致性。为了确认所提出方法的性能和有效性，还用文献中提供的测量值验证了获得的结果，获得了良好的相似性。
