【摘要】 针对同杆双回线短路故障,提出了基于正、负、零序量的故障分析方法,结合故障边界条件,给出了新的短路故障后电气量的求解方法,并给出了各种故障类型下的复合序网图。该方法在分析问题过程中保持了两回线的独立性,可用于某些特殊架设形式下的同杆双回线的故障—跳闸—合闸过程分析。更多还原

【Abstract】 For short circuit fault analysis on double-circuit transmission line,a method based on three sequences is put forward. Combining with the boundary conditions of fault,a new approach for calculating the faulty electric quantities is presented,and the interconnections of sequence networks of typical fault types are given. Because it keeps the independence of the two lines,it can serve as a basic theoretical approach for studying the process of fault inception,tripping and reclosing on double-circuit transmission lines with some special line construction modes such as different line parameters or voltage classes of the two circuits on the same tower.更多还原
