High voltage overhead transmission lines (HVOHTLs) often pass close to metallic pipelines. The parallelism between HVOHTLs and pipelines, where electromagnetic fields couple them, may cause several problems. If the pipelines are metallic, a corrosion problem has occurred because these fields induce an AC voltage on the pipelines. This paper presents a novel contribution of a low electrical hazard that can control by grounding the pipelines with a polarization cells system to mitigate the induced AC voltage without deteriorating the cathodic protection (CP) performance. This work further utilizes a comparative analysis of two different mitigation units: a potassium hydroxide polarization cell (KOH-PC) and the solid-state polarization cell (SS-PC) to decide which one of these methods is more suitable for cathodic protection distribution. This paper also explores the potential of the hill-climbing algorithm in optimizing the two proposed mitigation units’ parameters to guarantee better CP performance. Moreover, the effect of changing the numbers and parameters of polarization cells on both induced AC voltages and CP performance is introduced to achieve a global minimum DC voltage degradation. From the comparative analysis, it is observed that SS-PC is more controllable in comparison with KOH-PC in mitigating the induced voltage and minimizing the DC voltage disturbance. Therefore, the SS-PC is considered the most efficient mitigation technique due to fewer potential safety hazards produced. The proposed model is implemented through simulations on the MATLAB/Simulink platform with experimental validation. The obtained results reveal that the robustness of SS-PC in mitigating the induced voltage with minimum disturbance in the DC CP voltage. Also, it is found that the effectiveness of the hill-climbing algorithm for optimizing the polarization cell's parameters and has capable of compensating the cathodic protection disturbance.

高压架空输电线路 (HVOHTL) 通常靠近金属管道。HVOHTL 和管道之间的并行性（电磁场将它们耦合）可能会导致几个问题。如果管道是金属的，就会发生腐蚀问题，因为这些场会在管道上感应出交流电压。本文介绍了低电气危险的新贡献，可以通过将管道与极化电池系统接地来控制，以减轻感应的交流电压，而不会降低阴极保护 (CP) 的性能。这项工作进一步利用了两种不同缓解单元的比较分析：氢氧化钾极化电池 (KOH-PC) 和固态极化电池 (SS-PC)，以确定这些方法中的哪一种更适合阴极保护分布。本文还探讨了爬山算法在优化两个提议的缓解单元参数以保证更好的 CP 性能方面的潜力。此外，引入了改变极化电池的数量和参数对感应交流电压和 CP 性能的影响，以实现全局最小直流电压退化。从对比分析中可以看出，与 KOH-PC 相比，SS-PC 在减轻感应电压和最小化直流电压扰动方面更具可控性。因此，由于产生的安全隐患较少，SS-PC 被认为是最有效的缓解技术。所提出的模型是通过在 MATLAB/Simulink 平台上进行仿真并经过实验验证来实现的。获得的结果表明 SS-PC 在减轻感应电压方面的鲁棒性，同时对 DC CP 电压的干扰最小。此外，还发现爬山算法优化极化电池参数的有效性，并具有补偿阴极保护扰动的能力。
