Abstract

This study pioneers a proactive source-control strategy for mitigating electromagnetic interference (EMI) on buried pipelines through Static Var Compensator (SVC)-assisted power factor optimization of adjacent high-voltage transmission lines. An integrated framework couples electromagnetic modeling with electrochemical validation, establishing a quantitative correlation between induced current density (J_ind) and corrosion rates of API X70 steel (0.119→0.404 mm/year as J_ind increases 0→200 A/m²). For a 400 kV, 900 MW transmission line, the iterative optimization algorithm achieves an optimal power factor of 0.966, reducing J_ind from 24.14 to 19.99 A/m² maintaining compliance with the 20 A/m² safety thresho ldwhile simultaneously providing 434 MVAR reactive power savings. These results demonstrate three key contributions: (1) a novel cross-infrastructure application of SVC technology beyond traditional economic optimization, (2) a validated quantitative J_ind -corrosion relationship enabling risk assessment, and (3) a dual-benefit solution that enhances grid efficiency while safeguarding pipeline integrity in shared energy corridors.

svc辅助功率因数优化：电网效率和管道完整性管理的双重效益策略

本研究率先提出了一种主动源控制策略，通过静态无功补偿器（SVC）辅助的相邻高压输电线路功率因数优化，减轻埋地管道上的电磁干扰（EMI）。一个集成的框架将电磁建模与电化学验证相结合，建立了API X70钢的感应电流密度（Jind）与腐蚀速率之间的定量相关性（当Jind增加0→200 a /m²时，为0.119→0.404 mm/年）。对于400kv， 900mw输电线路，迭代优化算法的最优功率因数为0.966，使金德从24.14 a /m²降低到19.99 a /m²，保持了20 a /m²的安全阈值，同时节省了434 MVAR的无功功率。这些结果展示了三个关键贡献：(1)超越传统经济优化的SVC技术的新型跨基础设施应用；(2)验证的定量腐蚀关系，实现风险评估；(3)双重效益解决方案，提高电网效率，同时保护共享能源走廊中的管道完整性。
