Electric power communication access network design evaluation method based on multi-object decision-making

Abstract

The invention discloses an electric power communication access network design evaluation method based on a multi-object decision-making. The method specifically comprises the following steps that (1) an evaluation index library and an evaluation method library are established; (2) evaluation indexes and an evaluation method are determined through index inquiries; (3) single objects are evaluated through the evaluation method determined in the step (2); (4) based on a multi-object decision-making theory, multi-object decision-making is conducted according to evaluation results of the single objects, and a comprehensive evaluation result is obtained according to user demand weighing and mutual influences among different indexes and used for evaluating the advantages and the disadvantages of a design scheme and giving improvement measures. By means of the electric power communication access network design evaluation method, the four types of indexes of the economical efficiency, the technical character, the reliability and the safety of an electric power communication access network can be fully evaluated. The design scheme is effectively evaluated, the targeted improvement measures are given, the network planning and designing level is increased, and the intelligent development of power distribution and consumption network is better supported.

Description

technical field [0001] The invention relates to the technical field of electric power communication, in particular to a design evaluation method for electric power communication access network based on multi-objective decision-making. Background technique [0002] Different from the public telecommunication network, the power communication access network is a proprietary communication network of the power system, which involves basic links such as power production, dispatching, and control, and has high requirements for the real-time performance, reliability, and security of the network. The design and evaluation of power communication access network mainly includes two steps: the establishment of evaluation index system and the determination of evaluation test methods. Since the current electric power communication access network is generally constructed independently according to business needs along with the distribution and consumption of primary lines, the corresponding...

Problems solved by technology

Among them, the expert evaluation method, based on the subjective judgment of experts, combines the advantages of qualitative and quantitative methods, and can complete quantitative evaluation when the original data is insufficient; the mathematical evaluation method uses operations research and other mathematical methods to evaluate the evaluation object. Typical ones are the analytic hierarchy process, which can mathematically solve problems that require decision-making using fewer known conditions; new evaluation methods, such as gray comprehensive evaluation methods, rough set theory, and artificial neural network evaluation methods, are not Any knowledge other than data needs to be processed, and potential laws can be deeply excavated, but the mathematical modeling and calculation process is complicated; the mixed evaluation method combines several different evaluation methods to absorb their respective advantages, which is very suitable for multi-level Complex system evaluation with multiple structures, but the evaluation process is complicated, and it is difficult to correlate with the physical meaning of various indicators of the power system
