Method and system for registering events in wind turbines of a wind power system
First Claim
1. A method for registering events in a wind power system, said method comprising:
- mutually time synchronizing first and second data processors of said wind power system;
registering a first event in said first data processor;
registering a second event in said second data processor;
establishing a relative timing of said first and second events registered in said first and second data processors according to said time synchronization;
correlating said first and second events in the time domain based at least in part on said relative timing; and
determining whether said first and second events are related to a common triggering event based on a result of said correlation; and
controlling at least part of the wind power system based on the determination of whether said first and second events are related to the common triggering event.

Abstract
The invention relates to a method of registering events in a wind power system comprising at least two data processors, wherein the data processors of said wind power system are mutually time synchronized, wherein events are registered in said at least two data processors, wherein the timing of said events registered in different of said at least two data processors is established according to said time synchronization. According to an advantageous embodiment of the invention, events may be registered and preferably analyzed according to a common timing. This analyzing makes it possible to establish an analysis where events of different wind turbines are basically interrelated and where information regarding such interrelation is important or crucial for establishment of control or fault detection based on correctly timed events from different wind turbines.

15. A method for analyzing events of or controlling at least part of a wind power system comprising first and second data processors, said method comprising:
-
mutually synchronizing said first and second data processors of said wind power system according to a synchronized time; registering a first event in said first data processor; registering a second event in said second data processor; time stamping said first and second registered events; correlating said first and second registered and time stamped events in the time domain to determine if said first and second registered and time stamped events are related to a common triggering event; and controlling at least part of the wind power system based on said first and second registered and time stamped events. - View Dependent Claims (16, 17, 18)

19. A wind power system comprising:
-
a master clock; first and second data processors each including a slave clock; means for mutually synchronizing said slave clock of each of said first and second data processors according to said master clock; one or more sensors for registering one or more events occurring in said wind power system; means for creating one or more event data based on said one or more registered events; means for time stamping, in said first and second data processors, of said one or more event data, in accordance with said slave clock; and means for analysing the said event based on said time stamped event data or means for controlling at least part of said wind power system based on said time stamped event data, wherein said time stamped data in said first data processor is correlated with said time stamped data in said second data processor in the time domain to determine if said one or more events are related to a common triggering event.
