摘要
Abstract
With the connection of ultra-high voltage transmission lines and the expanding scale of power grid,the struc-ture of power systems is becoming more and more complex,leading to the existence of electromagnetic loop networks across the voltages of 1 000 kV,500 kV and 220 kV.Therefore,it is necessary to analyze different candidate decoupl-ing schemes.In traditional methods,BPA or PSASP is commonly used to obtain the power flow results and analyze the system stability,which is not an efficient method to comprehensively judge different schemes.In this paper,improved analytic hierarchy process(IAHP)combined with PSS/E is proposed to evaluate the decoupling schemes of electromag-netic loop networks.Firstly,the theory of IAHP is studied.Instead of the nine-mark method used in analytic hierarchy process(AHP),a three-mark method is used in IAHP to reduce the influence of subjective judgment on the evaluation results. Moreover,an optimal transfer matrix is used to establish the judgment matrix,thus omitting the consistency check of AHP. Then,considering the economical efficiency,security,stability and reliability of power systems,an evaluation index system for decoupling electromagnetic loop networks is proposed,and it is implemented with PSS/E and Python.Finally,the proposed method is tested using East China Power Grid,and simulation results demonstrate the effectiveness of the proposed method and the feasibility of the decoupling scheme.关键词
