A wind power plant predictive protection circuit

The present invention relates to a method of operating of a wind power plant comprising a circuit breaker and at least one wind turbine generator electrically connectable to an electrical grid through said circuit breaker, the method comprising the steps of detecting at least one condition for the circuit breaker to trip by means of a sensor; informing a control means of this detection prior to the circuit breaker disconnecting; and preparing the at least one wind turbine generator before said circuit breaker disconnects said at least one wind turbine generator from said electrical grid.
