Wind turbine data acquisition system

A computer program product being adapted to enable a computer system comprising at least one computer having data storage means associated therewith to perform a method comprising:

• providing a sensor network for state monitoring of a wind turbine, the sensor network includes one or more standard sensor modules, each standard sensor module comprising a sensor configured for measuring a standard parameter related to normal operation of the wind turbine or its surroundings at regular intervals or on an on-going basis, a processor configured for receiving input from said one or more standard sensor modules, and a data transfer channel configured for transferring sensor output from said one or more standard sensor modules to said processor, the method comprising:
• during the normal operation of the wind turbine, mounting an additional sensor module within the wind turbine or in relation to the wind turbine and configured to measure at least one non-standard parameter of or at the wind turbine;
• and
• connecting the additional sensor module to an auxiliary connection point of the data transfer channel, said auxiliary connection point being free during the normal operation of the wind turbine for connection of one or more additional sensor modules in surplus of standard sensor modules in a standard set-up of the wind turbine sensor network.
