| 总结: | An Analytic Hierarchy Process (AHP) approach been used for analysis, comparison and
classify the quality of several parameters that affect the conductor thermal ratings. The
method is based on pairwise comparison between several factors that affect the
alternatives in a hierarchical structure. The thermal ratings of power transmission lines is
basically based on the maximum permissible temperature of the conductors. Conductor
can lose their tensile strength due to thermal load or annealing. This paper analysis
thermal aging using known characteristics of transmission conductor, load information
and weather data. By analyzing the conductor temperatures, aging due to loss of
conductor tensile strength is estimated at individual locations along the transmission
corridor. The proposed methodology is illustrated using a case study analyzing a power
transmission line in Kluang, Johor. This information is important for transmission
network operating procedures, scheduling of line inspections, maintenance, or
reconductoring. |
