Research on Evaluation Method of Open-loop Scheme of Electromagnetic Loop Network Based on Comprehensive Weight

From a mathematical point of view, the evaluation of the open loop scheme of electromagnetic loop network is a multi-objective optimization problem. This paper combines subjective and objective weighting methods and takes fully into account the evaluation elements of electromagnetic loop network open-loop, and proposes an evaluation method based on comprehensive weighting for open-loop schemes of electromagnetic loop network. Firstly, the opening principle and mechanism of electromagnetic loop network are analyzed. On this basis, the comprehensive evaluation index system of the open loop scheme of the electromagnetic loop network is established by taking into account safety and stability of the system, current limiting effect and economic operation and so on. Then, in order to calculate the subjective and objective weight coefficient by using the analytic hierarchy process (AHP) and the coefficient of variation method and through the comprehensive evaluation calculation to obtain a comprehensive index to evaluate the advantages and disadvantages of the open-loop scheme. The rationality and validity of the method presented in this paper are verified through the example analysis of an actual grid in one province and the simulation analysis by using PSASP.
