局部耦合双回输电线路故障分析计算方法
Analysis and Calculation Method for Fault of Partial Coupling Double-circuit Power Transmission Lines
摘要
Abstract
Existing fault analysis method for double-circuit power transmission lines on the same tower is not applicable any more due to influence of mutual inductance among coupling lines. Therefore,this paper studies fault analysis on partial cou-pling double-circuit power transmission lines. According to structures and characteristics of partial coupling double-circuit transmission lines,sector equations for partial coupling double-circuit power transmission lines are established by using phase component method and port network theory. A kind of fault calculation method for partial coupling double-circuit power transmission lines is realized by combining fault boundary condition equation. Finally,electromagnetic transient simulation software ATP-EMTP is used for constructing a model for emulation proof and the result indicates that the proposed method has small errors in calculation and is not affected by transition resistance and fault types.关键词
