Example Embodiment

[0033] Step S1: Collect the data information of the state of the distribution automation terminal, and establish a hierarchical model for the evaluation of the state of the distribution automation terminal. Status data includes: operating status, inspection status, reliability of the same batch of equipment, overhaul status, and whether there are family defects, etc., which are divided into detection status, reliability, and failure risk status. And an improved state quantity, the data comes from the online monitoring system, patrol data, historical data, manufacturer information, etc., and the distribution automation terminal state evaluation hierarchical structure model is established through sufficient data information. The established hierarchical structure model such as figure 2 Shown.

[0034] Step S2: Use the analytic hierarchy process to determine the weight of each layer of the distribution automation terminal state evaluation.

[0035] The specific steps include:

Abstract

The invention discloses a method for evaluating the state of a distribution automation terminal based on an analytic hierarchy process (AHP). The method comprises the following steps: collecting the data information of the state quantity of a distribution automation terminal, establishing a state evaluation hierarchical model of the distribution automation terminal; determining the index weights of respective layers of the distribution automation terminal state evaluation by using the AHP; normalizing the weights of respective layers and multiplying each weight by one hundred, and obtaining the score of each index weight in a round-off way so as to develop the scoring rules of respective indexes; scoring and accumulating the indexes to use a total score as a relevant state level. The method may evaluate the state of the distribution automation terminal. Compared with a conventional manual weighting method, the method of the invention determines qualitatively and quantitatively the weights by using the subjective and objective mixed AHP so as to obtain the index scores thereby achieving more objective and comprehensive state evaluation and paving the way for distribution automation terminal state control.

Description

technical field [0001] The invention relates to the status evaluation of power distribution secondary equipment, in particular to a distribution automation terminal status evaluation method based on analytic hierarchy process. Background technique [0002] The safe and stable operation of distribution network is directly related to the reliability of electricity consumption of power users, and the construction of distribution automation is a key measure to improve the stable operation of distribution network. With the continuous deepening of smart grid construction, the number of distribution automation terminal equipment continues to grow, and the reliable operation of distribution automation equipment has a great impact on the stable operation of the distribution network. Currently, the maintenance of distribution automation terminals still uses Traditional troubleshooting and regular maintenance will increase the working pressure of maintenance personnel, making it diffic...
