To address the optimization problem of electric field intensity in multi-target areas under transmission lines, this work suggests combining the enhanced improved particle swarm optimization (IPSO) with the analytical hierarchy process (AHP). First, using finite element simulation software, a transmission line shielding model was created. Next, the number, erection height, and phase spacing of the shielding lines were studied in relation to electric field strength. Drawing on these results, field strength shielding in many target locations was optimized using the AHP-IPSO algorithm. Research has demonstrated that the electric field intensity beneath a transmission line can be greatly decreased by installing shielded cables, and that the peak field intensity can be decreased by 28.4% by installing three insulated wires. The AHP-IPSO algorithm effectively solved the multi-factor electric field shielding optimization problem, thus offering a novel method for addressing such problems. Compared to other algorithms, the AHP-IPSO algorithm exhibits better optimization performance and offers better shielding efficiency, while also accounting for the economic aspects of shielded wire erection.
