Embodiment

[0144] Taking the blades of a 1.5MW wind turbine in a high rain erosion wind field as an example, the sensors of the monitoring system are installed at a suitable position at the bottom of the tower. The position of the main wind direction of the fan is determined. The sensor is fixed on the bracket, and the bracket is pasted on the outer surface of the tower through magnetic attraction and structural glue, and the sensor is connected to the collection cabinet through the signal line. The collection cabinet is arranged on the bottom platform of the tower through bolt connection, and the collection cabinet enters the wind farm ring network through the network port and the wind farm ring network router at the bottom of the tower. The server is arranged in the booster station and connected to the ring network of the wind field. The server is connected to the SCADA of the wind field conventional monitoring system. It communicates with Scada through the Modbus soft gateway to obtai...

Abstract

The application relates to a method for monitoring blade leading edge erosion, comprising the following steps: collecting wind sweeping signals of blades through a sound sensor; The processing module performs quality inspection on the sound data, and screens out sound data with poor data quality; identifies whether there is corrosion on the leading edge of the blade and evaluates the severity of the corrosion, and gives an early warning message when the corrosion degree exceeds the set threshold. The method and system for monitoring blade leading edge corrosion of the present application can identify blade leading edge corrosion based on machine position level in time, provide alarm information before the blade leading edge corrosion damages to the structural layer, and support targeted and timely maintenance.

Description

technical field [0001] The present application relates to a method and system for monitoring corrosion of the leading edge of a blade, which are suitable for the technical field of damage monitoring. Background technique [0002] The blade is the key component of wind catching, and the specially designed aerodynamic shape is the key to ensure the wind catching ability. The aerodynamic shape of the blade tip area, especially the 1 / 3 length area of ​​the blade tip, is the most critical area. Damage to the aerodynamic shape of the blade tip area, especially the damage to the leading edge of the airfoil, will greatly reduce the power generation output of the fan. Therefore, ensuring the integrity of the aerodynamic shape in the operating life cycle of the wind turbine is a key operation and maintenance goal to ensure the power generation performance of the wind turbine. [0003] However, wind turbines operate in complex or even harsh environments all year round. In some areas, ...
