Abstract

The invention discloses an association method of wind data and transmission line body operation data. The method comprises the steps of S010 setting W as a wind external force set, E as a transmission line equipment set, D as a defect set and F as a fault set, and setting the attributes of W, E, D and F, S020 connecting data, S030 using a k-means algorithm to carry out the scalarization of wind data, S040 using Apriori to search a frequent item, and finding a result which is in accordance with support and confidence, S050 setting a pre-condition lhs and a post-condition rhs, and filtering the result, and S060 restoring scalar wind data. According to the method, a reference basis is provided for the targeted maintenance of a transmission line and the reduction of the occurrence of fault defects.

Description

technical field [0001] The invention belongs to the field of electric power systems, and more specifically relates to a method for associating wind data with operation data of a power transmission line body. Background technique [0002] Since the transmission line is put into operation, as time goes by, power operation and maintenance management needs to grasp the changes in the state of the line itself. Transmission line is different from general equipment, it is a complex of many equipment. It is difficult to measure their health with simple indicators. A common practice in the electric power industry is to judge by counting the frequency of occurrences on the line. The line condition can be divided into fault type and defect type. Faults will seriously affect the normal transmission and power supply of transmission lines, such as tripping, disconnection, etc. will cause large-scale power outages. Defects are mainly some secondary risks, which do not directly have a s...
