Weight dynamic distribution method for power distribution automation terminal state evaluation indexes

Abstract

The invention provides a dynamic weight distribution method for state evaluation indexes of a power distribution automation terminal, and the method comprises the steps: obtaining respective initial weights of all state evaluation indexes of the power distribution automation terminal through a power distribution network operation and maintenance standard and expert experience; then independently adjusting the index weights of the state bid evaluation indexes of which the measurement data is changed according to the initial result of the state evaluation of the power distribution automation terminal, the interval of the normalized value of the state index and the change of the state index, and finally carrying out secondary adjustment on all the state evaluation indexes. And the distribution automation terminal state evaluation index weight distribution consistency is ensured. According to the method, the weight of a part of rapid deterioration indexes in the state evaluation of the power distribution network automation terminal is dynamically adjusted, the rapid deterioration condition of the indexes in the final evaluation result of the power distribution automation terminal is highlighted, and the situation that the state evaluation result cannot be reflected due to overall failure of the power distribution automation terminal caused by a single element fault is avoided.

Description

technical field [0001] The invention belongs to the field of electric power technology, and in particular relates to a method for dynamically assigning weights of power distribution automation terminal state evaluation indexes. Background technique [0002] Distribution automation terminal is mainly used for voltage and current data collection and monitoring, distribution switch status collection and opening and closing remote control during normal operation of distribution network. The distribution automation terminal is an important part of the distribution automation system. The status evaluation of the distribution automation terminal is helpful to realize the condition maintenance of the distribution automation terminal with a wide distribution and a large number. [0003] There are many components that determine the operating status of distribution automation terminals, generally including components related to remote signaling functions, related components of remote c...

Problems solved by technology

This state evaluation method can obtain effective results when the distribution automation terminal is in normal operation, but when one or several state evaluation indicators deteriorate rapidly, due to the low weight distribution of these state evaluation indicators, it will lead to The final state evaluation results of the distribution automation terminal do not change much, which often happens in the distribution automation terminal mainly composed of electronic components, so the operation and maintenance personnel of the distribution network will ignore the upcoming problems of the distribution automation terminal. Risk of damage, difficult to schedule maintenance work in advance
