Timestamping in wind turbines

摘要

The invention provides a method of collecting event data in a wind park installation comprising a plurality of wind turbines (1), each inluding a satellite-based clock (7). In each of said wind turbines (1) a first time signal is distributed from said satellite-based clock (7) to at least one node (4) in the wind turbine (1). In the at least one node (4) events happening in at least one subsystem connected to the node (4) are detected. When an event is detected, event data comprising an information about the event is collected. For each piece of collected event data, a timestamp is added to the piece of collected event data characteristing a corresponding instant of time when the event was detected. The timestamped event data is stored for later inspection.
