| 摘要 |
A method and system for improving the efficiency of energy capture from an energy capture device by analysis of the downstream fluid wake created by the energy capture device. In an illustrated embodiment, the system (10) comprises a sensing arrangement (32) configured to acquire air flow data from a downstream wake (34) produced by rotating blades (20) of a wind turbine (12), the sensing arrangement (32) comprising a Lidar unit (35) having an optical source (36) and a receiver (38). In use, the sensing arrangement (32) acquires data relating to the air flow velocity in the wake (34), which data is then processed to determine the relative angle of the wind turbine (12) and the average direction (D) of the incident resource (W). |
