| Abstract: |
| The element protection operation all over China' s grids in 2003 are introduced,including 100 MW and above generator protection,50 Mvar and above synchronous condenser protection,220 kV and a-bove transformer protection,220 kV and above bus protection and failure protection. With fault examples, protection misoperations are analyzed, and their reasons and responsibilities are pointed out. The information of element protection faults is exchanged, and the experiences and lessons are summarized, which helps to improve the whole operation level of element protections. |
