Icing monitoring and self-adaptive deicing integrated system and method for wind power blade

Abstract

The invention discloses an icing monitoring and self-adaptive deicing integrated system and method for a wind power blade. An upper computer is connected with a multi-channel signal control and processing module. The multi-channel signal control and processing module is connected with the input ends of monitoring transducer arrays and the input ends of deicing transducer arrays arranged on the wind power blade through a power amplifying module. The output ends of the two kinds of arrays are connected with a pre-amplifying module. The pre-amplifying module is connected with the multi-channel signal control and processing module. A sequential control unit is connected with a multi-channel excitation signal generation unit and a multi-channel echo signal processing unit. The transducer arraysgenerate ultrasonic guide waves to the wind power blade, and echo signals are received by the transducer arrays again and are sent to the multi-channel echo processing unit after being processed by the pre-amplifying module. By the adoption of the wind power blade icing monitoring and self-adaptive deicing integrated system and method, quantitative monitoring of comprehensive information such asblade icing positions and areas is achieved, strength-controllable and region-setable active deicing is conducted, deicing and icing prevention are more efficient, and energy saving and intelligence are achieved.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic guided wave non-destructive testing and power guided wave application in the new energy industry, and specifically relates to a system and method for integrating wind power blade icing monitoring and self-adaptive deicing. Background technique [0002] my country has abundant wind energy reserves, but the wind resources are mainly distributed in the cold north, high altitude and coastal areas. According to statistics, the wind speed increases by about 0.1m / s for every 100 meters above the altitude of 1000 meters. In high altitude and cold areas, icing Become the biggest problem affecting the efficiency and safety of fan operation. The icing of wind turbine blades will change the external shape and aerodynamic performance of the blades, increase the blade resistance, reduce the lift force, affect the maneuverability and stability of the whole machine, and eventually lead to a decrease in the conv...
