Abstract

The investment of multi-circuit transmission lines on the same tower has solved the problem of land occupation by transmission lines, but it has caused the harm of induced electricity. In order to analyze this kind of induced power problem and make suggestions for maintenance personnel, this paper uses EMTP software and distributed parameter method to accurately calculate and model 500kV / 220kV four-circuit transmission lines on the same tower. The calculation results show that: when the grounding switch at both ends of the maintenance line is grounded, the electromagnetic induction current is 90.122 A, which is much larger than the safety limit. Therefore, despite the double-ended grounding of the line, workers still need to wear protective clothing to ensure safe operation.
