摘要： A method of lowering a wind turbine blade after removal from a wind turbine lowers the blade in a vertical position to a point near the ground, and rotates it to a horizontal position for emplacement on a cradle. A winch is situated in the nacelle of the wind turbine. A cable extends downward from the winch to the blade root where it may be secured to a load cell. A tip end shoe is placed around the lower portion of the blade, and includes a crane hook receiving component that is used when the blade orientation is being changed. Tag lines are attached to the root and the tip end shoe, and extend to points on the ground where technicians manipulate them to prevent the blade from being blown into the tower.

摘要： Disclosed is a system and method for monitoring wind turbines, generally comprising a microphone for picking up acoustic emissions from a wind turbine and outputting a signal corresponding to the emissions; a filter for splitting the signal into a plurality of signals according to a plurality of frequency bands; and a processor for processing the plurality of signals and generating sound level data corresponding to at least a subset of the frequency bands. The system compares the sound level data with a sound threshold and generates an alarm signal when the sound level data exceeds the sound threshold. Alternatively, the system may include different thresholds corresponding to the different frequency bands, and an alarm can be generated when one or more of the different thresholds are exceeded by the different signals in the different frequency bands.

摘要： Models for predicting ice formation and/or accumulation on wind turbine blades and methods of their use in optimizing performance of wind turbines in the presence of adverse local weather conditions are disclosed. In certain embodiments, the predictive models include historical data of local meteorological conditions including, inter alia, wind speed, temperature, and relative humidity conditions and are useful, inter alia, for preemptively managing performance of wind turbines operation/shutdown cycles in response to a future predicted blade icing event based on a model of the present invention.

摘要： The present invention includes a Computer Assisted Reset (CAR) system that allows a central operations team to remotely reset turbine faults across multiple wind turbine platforms and SCADA systems with a single interface. The system also allows automatic resets to occur. One aspect of the invention includes a Modbus to OPC Translator. The translator permits the implementation of a system where a PLC located at wind turbine control sites can accept control messages or commands organized or formatted in accordance with the Modbus protocol and sent over an Internet Protocol connection, with the translator receiving the requests through the PLC and generating an appropriate OPC (“OLE Process Control”) request. The OPC request may then be passed onto a corresponding OPC server residing in the SCADA system for each wind turbine control site.

摘要： A controller of a power generation system provides, in response to a request or a determination to initiate a heating mode for a photovoltaic (PV) array, a first instruction to an inverter coupled between the PV array and a power grid to apply an initial backfeed voltage on PV modules of the PV array. The PV array comprises a plurality of strings of PV modules coupled in parallel, and a first subset of the strings of PV modules are online and a second subset of the strings of PV modules are offline. The controller monitors current data from a set of current sensors that each measure current provided from a corresponding set of strings of PV modules of the plurality of strings of PV modules of the PV array. The controller also provides a second command to the inverter to adjust the backfeed voltage.

摘要： Systems and methods for allocating electrical energy within a storage cell. Energy stored in an energy storage cell is allocated to multiple energy sub-partitions. Each energy sub-partition is associated with a user. A request to buy an amount of energy from an energy sub-partition assigned to another user is sent by a present user to at least one respective user in the plurality of users. Based on sending the request to sell an amount of energy, at least one response with an offer to sell energy to the present user is received. Acceptance of a selected offer within the at least one response is received, where the selected offer was sent by a winning user. The amount of energy is re-allocated from an energy sub-portion allocated to the winning user to an energy sub-portion associated with the present user based on receiving the acceptance.

摘要： One example includes a test illumination system comprising a light source and a location controller configured to generate location data associated with a real-time location of the test illumination system. The test illumination system can be configured to move relative to a solar panel array in response to a solar testing protocol to provide illumination from the light source at a defined illumination time to each solar panel of the solar panel array in a sequence to provide a voltage amplitude. The system also includes a solar panel testing controller configured to correlate the location data of the test illumination system, the defined illumination time, and the voltage amplitude for each solar panel of the solar panel array in the sequence to determine an efficacy of each solar panel of the solar panel array.

摘要： Systems and methods to monitor a wind turbine azimuth drivetrain. Azimuth variation characteristics data are accumulated from wind turbines over a period of time. Clusters of values within the azimuth variation characteristics data are identified and a respective condition of the main drivetrain is associated with different clusters of values. After the associating, a measured set of azimuth variation characteristics data is received. A cluster corresponds to values in the measured set of azimuth variation characteristics data is determined and a condition associated with that cluster is determined to be a condition associated with the subject main drivetrain. That condition is then reported.
