Field-effect limits and design parameters for hybrid HVDC – HVAC transmission line corridors

Abstract

The scientific evaluation of extra-high voltage (EHV) and ultra-high voltage (UHV) hybrid transmission lines presents essential research demands for power transmission systems’ efficiency. The high-capacity transmission lines need proper electric and magnetic field (EMF) management because public concerns about environmental and health risks keep rising. The relationship between power grid lines and surrounding areas needs thorough study to fulfill health-related requirements and earn public trust in power projects. The experiments demonstrated in Figure X show that strategic grounding with clever conductor placement effectively reduces EMF exposure, which results in enhanced performance and social acceptance of transmission lines in urban environments. In EHV/UHV lines, the Right of Way (ROW) is fundamental in establishing these power systems’ operational efficiency and safety. The need for broader corridors stemming from EMF considerations and corona discharge concerns requires designers to achieve ideal solutions between effectively using land space and maximizing electrical system efficiency. The design optimization needs to integrate technological innovations for future energy growth because this will reduce environmental impacts throughout the design process. Combining design strategies is crucial for protecting power transmission systems against upcoming energy requirements and regulatory changes. Evaluating corona effects influences the complete functional performance and design strategies for these power transmission lines. The environmental conditions that trigger corona discharge, especially when combined with ice accumulation, result in power losses and environmental damages, thus requiring designers to grasp its impact on lines thoroughly. Many publications present effective laboratory methods for studying icing phenomena that affect severe weather areas. The research discoveries help reduce power losses and simultaneously support the secure integration of EHV/UHV systems into existing electrical networks. This investigation addresses multiple elements in depth to create better design procedures that promote efficiency with safety and environmental sustainability.
