Abstract

The invention discloses a monitoring device and method of aerodynamic loads of rotating blades of a floating type fan scale model, and relates to the technical field of wind power generation. The device comprises a blade assembly module, a wind wheel spindle module, an optical fiber sliding ring module, a wind wheel driving module, and a signal processing module; the monitoring method of the device comprises the four steps of parameter presetting, data collection, data processing and data saving. On the premise of not affecting the other property needs of basin test of the floating type fan scale model, the work loads of the rotating blades are monitored in real time, the load information is transmitted to the shore signal processing module in real time safely and reliably, and the technical effects of being simple in device, low in cost, short in test period and the like are achieved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a device and method for monitoring the aerodynamic load of a floating fan scale model rotating blade. Background technique [0002] As a new form of wind power generation, the appearance and development of floating wind turbine technology can realize the exploitation and large-scale utilization of ocean wind resources, and has broad application prospects. However, due to the complexity and uncertainty of marine environmental loads, especially the load of wind turbine blades, the load presents significant nonlinear, strong time-varying, and high coupling characteristics. Deep and thorough understanding. The scale model pool test can be used as an important way to study the overall dynamic behavior of floating wind turbines and evaluate the performance of floating platforms and wind turbines. It is of great academic and engineering significance to provide guidance f...
