Abstract

The electrical field is a function of both the voltage and the configuration of the overhead transmission line (OTL); thus, mitigation of the electrical field could be achieved by either electrical compensation or mechanical rearrangement of the line configuration. In the mechanical rearrangement method, the conductor positions are optimized under certain constraints so that the electrical field has the minimum possible value. In the proposed research, OTL mechanical rearrangement is improved using electrical compensation based on a genetic algorithm (GA). The electrical compensation is implemented by inserting a combination of passive series and shunt elements in each phase, creating an electric voltage imbalance. GA is an evolutionary optimization algorithm used to minimize the electric field near residences as a fitness function. The positions of conductors and passive-reactive elements are represented as genes. In addition, this paper includes a case study on a 500-kV high-voltage overhead transmission line. The results show that when passive-reactive compensation is combined with mechanical compensation, the lowest electric field can be obtained. Electrical compensation improves the mechanical rearrangement method by approximately 18.6% (the total reduction with mechanical compensation of only about 34% is increased to more than 52% with electromechanical compensation).

利用基于遗传算法的机电补偿缓解架空输电线路附近的电场

电场是电压和架空输电线路（OTL）配置的函数；因此，可以通过电气补偿或线路配置的机械重排来减轻电场。在机械重新排列法中，导体位置在一定的约束条件下进行优化，从而使电场值尽可能小。在拟议的研究中，基于遗传算法（GA）的电气补偿改进了 OTL 机械重新排列。电气补偿通过在每个相位插入无源串联和并联元件组合来实现，从而产生电压不平衡。遗传算法是一种进化优化算法，用于将住宅附近的电场最小化，作为一种适应度函数。导体和无源反应元件的位置表示为基因。此外，本文还对一条 500 千伏高压架空输电线路进行了案例研究。结果表明，当被动反应补偿与机械补偿相结合时，可以获得最低电场。电气补偿比机械重排法提高了约 18.6%（机械补偿的总降低率仅为 34%，而机电补偿则提高到 52%以上）。

期刊介绍： The impact of computers has nowhere been more revolutionary than in electrical engineering. The design, analysis, and operation of electrical and electronic systems are now dominated by computers, a transformation that has been motivated by the natural ease of interface between computers and electrical systems, and the promise of spectacular improvements in speed and efficiency. Published since 1973, Computers & Electrical Engineering provides rapid publication of topical research into the integration of computer technology and computational techniques with electrical and electronic systems. The journal publishes papers featuring novel implementations of computers and computational techniques in areas like signal and image processing, high-performance computing, parallel processing, and communications. Special attention will be paid to papers describing innovative architectures, algorithms, and software tools.
