| Abstract: | This paper researched on zero-sequence circle current,deadlock between transformer zero-sequence over-current relays,optimization of coordination results and universality of coordination software.The direction of zero-sequence circle current was definitely analyzed.Valid methods breaking the deadlocks and a method for optimization of coordination results are put forward.Based on induction of the coordination principles,universality of software is realized by optional principles.It is proved that the coordination software based on above achievements can meet the requirements of auto-coordination of transformer zero-sequence over-current relay in different areas. |
