Abstract
A control system for a wind power plant that includes a damage module and a control module. The damage module compares existing stress conditions on one or more component parts of the wind power plant to current energy generating costs. The control module alters electric power generated by the wind power plant based upon the comparison.
Claims23
A control system for a wind power plant, comprising:
- a damage module operable to compare existing stress conditions on one or more component parts of the wind power plant to current energy generating costs;
- and
- a control module operable to alter electric power generated by the wind power plant based upon the comparison.
A method, comprising:
- comparing existing stress conditions on one or more component parts of a wind power plant based upon local meteorological conditions to energy generating costs at that time;
- and
- controlling blade pitch of one or more turbine blades of the wind power plant based upon the comparison.
An apparatus, comprising:
- means for comparing existing stress conditions on one or more component parts of a wind power plant based upon local meteorological conditions to energy generating costs at that time;
- and
- means for controlling blade pitch of one or more turbine blades of the wind power plant based upon the comparison.
A control system for a wind power plant, comprising:
- a stress module operable to statistically determine existing stress conditions on one or more component parts of the wind power plant and then compare the statistically determined existing stress conditions to predicted stress distributions;
- and
- a control module operable to alter electric power generated by the wind power plant based upon the comparison.
