摘要：
A line protection setting program for power system zero-sequence current is developed in which several problems are solved: the calculation method for changing operating mode by modifying impedance matrix, the analysis of zero-sequence mutual coupling of lines, zero-sequence analysis in the course of non-three-phase operation and the calculation for protection range of zero-sequence current.
