Abstract

The intelligent substation project has a high workload, high error rate, and low efficiency in SCD virtual terminal connection. A technique for automatically generating virtual circuits has been proposed to improve the efficiency of SCD virtual terminal connections. Using the virtual circuit design template, this article first uses the K-nearest neighbor learning method to automatically match virtual terminals. On the basis of training data, a weight vector optimization model will be constructed, with weight vectors as optimization parameters and appropriate objective functions set. By using an improved simulated annealing algorithm to solve the weight optimization model, the optimal solution of the distance weight vector is obtained. The verification through examples shows that compared to existing technologies, this method obtains more accurate virtual terminal connection results and higher matching efficiency.

期刊介绍： Electric Power Systems Research is an international medium for the publication of original papers concerned with the generation, transmission, distribution and utilization of electrical energy. The journal aims at presenting important results of work in this field, whether in the form of applied research, development of new procedures or components, orginal application of existing knowledge or new designapproaches. The scope of Electric Power Systems Research is broad, encompassing all aspects of electric power systems. The following list of topics is not intended to be exhaustive, but rather to indicate topics that fall within the journal purview. • Generation techniques ranging from advances in conventional electromechanical methods, through nuclear power generation, to renewable energy generation. • Transmission, spanning the broad area from UHV (ac and dc) to network operation and protection, line routing and design. • Substation work: equipment design, protection and control systems. • Distribution techniques, equipment development, and smart grids. • The utilization area from energy efficiency to distributed load levelling techniques. • Systems studies including control techniques, planning, optimization methods, stability, security assessment and insulation coordination.
