特高压输电线路潜供电弧的物理模拟与建模综述
Survey on Physical Simulation and Mathematical Modelling for Secondary Arcs of UHV Transmission Lines
摘要
Abstract
In spite of elucidating the general design of the test circuit, the layout of the arc ignition equipment, the choice of the value and duration for the short currents, the wind velocity and its direction were all summarized to the question of equivalence of simulating test for secondary arcs, including the obstacles and the deficiency of it. The setup and the procedure of the field test for secondary arcs were introduced,especially for that of ultra high voltage transmission lines home and abroad. The empirical formula for the secondary arc duration nowadays were put forward. While describing and comparing the advantages and deficiencies of the existing black-box model and the physical models, the research status for modeling the secondary arcs were introduced. The key issues encountered while revealing the inherent mechanism and modeling of the secondary arcs were elaborated. On this basis,the characteristics of the secondary arcs under different conditions of novel transmission lines were analyzed.Referential suggestions for the secondary arc test and modeling were also presented.关键词
