| Abstract: | Inappropriate earth modes of 35 kV pool line in wind farm would affect safety and operation of wind farm or power grid. In this paper,situation of 35 kV neutral point earthed in wind farm was introduced. And hazard of arc earth was analyzed as well as practical cases. Conclusion was drawn that non-solid earthed mode for pool line of 35 kV wind power generator could ensure safety of wind farm and power grid with tripping of earthed protection. |
