| 20100280673 | Systems and Methods for Analyzing Reporting Data - Embodiments of the invention include systems and methods for analyzing reporting data. According to one embodiment a system for analyzing reporting data is provided. The system can include at least one communication interface, at least one memory operable to store instructions, and at least one processor in communication with the communication interface and the memory. The processor can execute the instructions to: extract historical data associated with the operation of at least one machine; generate an output of an analytical report based on the historical data; automatically identify an indication of at least one machine status by processing the output of the analytical report with respect to at least one trigger condition associated with the indication of the machine status; and generate an alarm in response to automatically identifying the indication of the machine status. | 11-04-2010 |
| 20100138058 | POWER PRODUCTION CONTROL SYSTEM AND METHOD - A control system for an energy production facility includes a plant controller for receiving an indication of a measured power output of the energy production facility that includes power generators and produces output signals. The system also includes a processing unit operably coupled to the plant controller and responsive to executable computer instructions when executed on the processing unit cause the plant controller to: create an output signal that causes an energy storage device to discharge in the event power reserves of the power generators can not met the requested ramp down rate; and create an output signal that causes the energy storage device to charge up in the event that the power capability of the power generators can meet the requested ramp down rate. | 06-03-2010 |
| 20100133815 | Method and Apparatus for Operating a Wind Turbine During a Loss of Communication - A method for operating a wind turbine during a loss of communication is described that includes coupling a pitch controller to at least one wind turbine blade and to a wind turbine controller, establishing communication between the pitch controller and the wind turbine controller, and detecting a loss of communication between the pitch controller and the wind turbine controller. After a loss of communication is detected, the method further includes waiting for a first predetermined amount of time to elapse, independently pitching the at least one wind turbine blade to a predetermined position, waiting for a second predetermined amount of time to elapse, and maintaining the at least one wind turbine blade in the predetermined position until a rotation of the at least one wind turbine blade stops. | 06-03-2010 |
| 20100109334 | WIND TURBINE FLUID FILTERING SYSTEM - A wind turbine power generation system is disclosed that includes a backflushing filter system. The backflushing filter system may be include a backflushing filter in fluid communication with in any one of the hydraulic pumping system, a gearbox oil circuit, a mainbearing oil circuit, a brake oil circuit, and combinations thereof. The backflushing filter system further includes a containing filter for removing particulate contamination from the backflushing filter system. | 05-06-2010 |
| 20100097220 | WIRELESS INFORMATION SYSTEM FOR WIND TURBINE COMPONENTS - A wireless information system for wind turbine components is disclosed. The wireless information system includes radio-frequency identification (RFID) tags that are attached to wind turbine components. The RFID tags contain component information such as identification, commissioning date, and maintenance information. The system allows the components to be identified and/or verified by a technician. The technician may use a handheld device, which permits the RFID tag to be read at various locations. | 04-22-2010 |
| 20100054940 | WIND TURBINE BLADE CLEANING METHOD - A method for cleaning the blades of a wind turbine using precipitation. The method includes determining the presence or absence of precipitation. In response to the determination of the presence of precipitation, adjusting the rotor speed to increase the speed of the blades and/or adjusting the variable pitch drive to increase the pitch of the blades. The combination of the increased blade speed and/or the increase blade pitch and the presence of precipitation facilitate the removal of debris from the blades by the precipitation. | 03-04-2010 |
| 20100021278 | PORTABLE CRANE SYSTEM FOR WIND TURBINE COMPONENTS - A portable crane assembly for servicing a wind turbine. The crane assembly includes a first primary support member and a second primary support member being rotatably attached to one another. The first primary support member is configured to attach to a wind turbine component. The second primary support is coaxially rotatable with respect to the first primary support member. The crane assembly further includes a boom member pivotably attached to an end of the second primary support member. The portable crane assembly is disassemblable into components that can be manually carried. A wind turbine servicing system and a method for servicing a wind turbine are also disclosed. | 01-28-2010 |
| 20090295165 | METHOD FOR WIND TURBINE PLACEMENT IN A WIND POWER PLANT - A method for determining wind turbine location within a wind power plant based on at least one design criteria. A wind turbine layout including at least one wind turbine location is prepared and site conditions at each wind turbine location are determined. One or more plant design metrics are evaluated in response to the site conditions. The plant design metrics are analyzed in response to the site conditions. The method further includes applying constraints to the wind turbine layout and comparing the plant design metrics to the design criteria and constraints. Thereafter, the wind turbine locations are selectively adjusted within the layout in response to the comparing step until a stop criteria is reached. | 12-03-2009 |
| 20090295160 | METHOD FOR INCREASING ENERGY CAPTURE IN A WIND TURBINE - A method for operating a wind turbine. The method includes providing a wind turbine having a variable speed control system, the control system having an initial rotational speed set point. At least two operational parameters are obtained from one or more sensors. An adjusted rotational speed set point greater than the initial rotational speed set point is determined in response to the operational parameter. The control system is configured with the adjusted rotational speed set point. A wind turbine and wind turbine plant are also disclosed. | 12-03-2009 |
