What are the major challenges and solutions in long-distance power transmission?
2025-08-10Answer: Long-distance power transmission faces several technical and logistical challenges:
-
Power Loss: The primary challenge is energy loss due to conductor resistance (I²R loss) and corona discharge, which becomes more pronounced at higher voltages.
-
Voltage Stability: Maintaining a stable voltage over long distances is crucial for preventing voltage drops, which can disrupt the grid and damage equipment.
-
Electromagnetic Interference (EMI): High-voltage lines generate strong electromagnetic fields that can interfere with communication systems.
These challenges are overcome through several solutions, many of which our equipment is designed to facilitate:
-
Using higher transmission voltages and bundled conductors to minimize corona discharge and resistance.
-
Implementing HVDC technology for ultra-long distance projects.
-
Employing advanced substation automation and compensation devices like shunt reactors to maintain voltage stability.
-
Strategic line routing and shielding to mitigate EMI.
