Limiting electric fields of HVDC overhead power lines

Area of Science:

• Electrical Engineering
• Environmental Health
• Power Systems

Background:

• Growing reliance on renewable energy necessitates long-distance power transmission.
• High-voltage direct current (HVDC) overhead power lines are expanding in Europe.
• Current regulations lack guidelines for static electric field (SEF) exposure from HVDC lines.

Purpose of the Study:

• To analyze static electric fields (SEFs) generated by HVDC overhead power lines.
• To investigate potential adverse health effects associated with SEFs.
• To derive criteria for limiting SEF strength in HVDC line design and regulation.

Main Methods:

• Theoretical analysis of static electric fields.
• Experimental data collection and evaluation.
• Development of health-risk-based criteria for SEF mitigation.

Main Results:

• Identified key parameters influencing SEF strength in HVDC lines.
• Established correlations between SEF exposure levels and potential health impacts.
• Proposed specific criteria for limiting SEF strengths to ensure public safety.

Conclusions:

• Static electric fields from HVDC lines require regulatory attention.
• Derived criteria provide a basis for safer HVDC infrastructure.
• Further research and implementation of SEF limits are recommended for sustainable energy expansion.
