title = "Based on FAHP Evaluation of Equipotential Method of Live Working on ±800kV UHVDC in Transmission Line in Heavy Icing Area",
abstract = "UHV 800kV DC transmission line is a key power facility for long-distance and large-capacity power transmission. Its operational reliability is important to ensure the operational safety of the sending and receiving terminal power grids, and live working is an important technical means to improve the operational reliability and utilization of the line by eliminating defects in a timely manner. To comprehensively evaluate the safety of different equal potential methods of live working of ± 800kV transmission line, this paper analyzes the factors affecting the entry path and establishes a path evaluation model based on the fuzzy analytic hierarchy process (FAHP). The optimal and most commonly used entry paths are selected for weight calculation, including the entry model with the lowest electric field on the body surface (135 ° entry), the entry mode with low arc energy (45° entry), and the commonly used ones (The horizontal hanging basket entry and the upper rope ladder access) were compared and calculated. The calculation results show that the 45°hanging basket method is the best path scheme for comprehensive evaluation. The evaluation method can provide data reference for safety protection of ± 800kV UHVDC live working.",
