摘要
Abstract
Accurate calculation of fault current is the foundation of thermostability verification of OPGW and selection of ground wires. The widely application of OPGW, especially the new technologies of ground connection modes, such as graded insulation, transposition and open loop, which are designed to reduce the ground electromagnetic induction power loss, make the ground system more complex. On the basis of phase coordinate model, a method of large scale circuits is proposed to compute the single phase short-circuit in complex ground system conveniently. Numerical examples demonstrate the presented methods are feasible and effective, and the single phase short-circuit distribution characteristic of UHV AC transmission lines under different ground systems is analyzed in detail, supplying beneficial references in electric power construction.关键词
