Patent Images
1. A wind farm comprising:
- a plurality of wind turbine data acquisition systems, each data acquisition system comprising;
a plurality of sensors, each sensor configured to detect a parameter associated with a condition of a respective component of a wind turbine and to provide sensor data based at least in part on the parameter;
a plurality of modules, each module coupled to at least one sensor and configured to receive the sensor data from the at least one sensor and to generate module output data based at least in part on the received sensor data;
a local data concentrator, the local data concentrator configured to transmit commands to one or more of the modules, to receive module output data from one or more of the modules and to provide the received module output data to a server; and
a serial bus configured to couple the plurality of modules and the local data concentrator,wherein at least one data acquisition system is mounted on each wind turbine in the wind farm and the server is configured to provide an estimate of a remaining useful life of a selected component of a selected wind turbine to a user based at least in part on a representation of the condition of the selected component of the selected wind turbine.

Abstract
Generally, a system and method consistent with the present disclosure may provide a relatively low cost, relatively robust data acquisition and analysis system useful for condition-based maintenance. The system may be useful for condition-based maintenance in industrial applications, e.g., of equipment and/or machinery. The industrial monitoring system may be used, for example, to monitor a condition of rotating machinery, e.g., a wind turbine. The system and method may include data analysis that may be useful for anticipating a need for maintenance, repair and/or replacement of one or more components.

17. A method of determining an estimate of a remaining useful life of a monitored component of a wind turbine, the method comprising:
-
detecting a parameter associated with a condition of the monitored component of the wind turbine using a sensor coupled to the monitored component of the wind turbine and providing sensor output data to a module based at least in part on the parameter; generating module output data based at least in part on the sensor output data; providing the module output data to a local data concentrator in response to a command from the local data concentrator; providing the module output data to a server; and estimating the remaining useful life of the monitored component of the wind turbine based at least in part on a representation of the condition of the monitored component of the wind turbine. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26)
