The solution of the ground fault using GOOSE message in the wind farm system

Wind farm systems presented some unique challenges for protection. Ground faults on feeders will result in unfaulted phase voltages rising to line levels and transient over voltages can be produced, which can degrade insulation, resulting in eventual equipment failure. This paper focused on the particular problem of feeder ground faults. A novel, yet simple solution is presented that makes use of a peer-to-peer fast message - GOOSE message. It designed and implemented information and communication model of the Wind-Turbine-Generator (WTG) IED. And it introduced the timing sequence for a feeder fault using the transfer trip solution. Finally GOOSE message is designed to transfer trip information. By Simulation test of GOOSE message and analyzing sequence diagram of IED´s interaction for transfer trip, we know that wind turbine equipment can be avoided damage using GOOSE message, which is a good solution of the ground fault.
