Wind Turbine Multi-field Parameter Synchronous Monitoring System

Abstract

The invention discloses a synchronous monitoring system for multi-field parameters of a wind turbine. The system comprises a test bench, a wind turbine generator set, a flow field monitoring subsystem, a dynamic parameter monitoring subsystem of a rotating body structure, a dynamic parameter monitoring subsystem of a non-rotating body structure, a generator output parameter monitoring subsystem and a trigger integrated control subsystem. The flow field monitoring subsystem injects smoke into the air flow inlet end of the test bench, and the simultaneous correlation monitoring of blade tip flow fields and tip vibration displacement is achieved. The dynamic parameter monitoring subsystem of the rotating body structure collects acceleration signals and strain signals of blades of the wind turbine and conducts conversion. The dynamic parameter monitoring subsystem of the non-rotating structure achieves conversion of the acceleration signals or the strain signals of the fixed position on the wind turbine. The trigger integrated control subsystem achieves operation time sequence control of all the subsystems. By the adoption of the synchronous monitoring system, simultaneous monitoring of the wind turbine flow field parameters, the structural dynamic parameters and the generator output parameters can be achieved, and the test system support is provided for the correlation analysis among the various field parameters.

Description

technical field [0001] The invention relates to the technical field of collaborative testing of wind turbine multi-field parameters, in particular to a synchronous monitoring system for wind turbine flow field parameters, structural dynamic parameters, and generator output parameters. Background technique [0002] As the world's fossil energy depletion intensifies, wind energy will undoubtedly become one of the mainstays of human energy development in the future. The versatility of wind turbines in complex natural environments (such as ventilation and energy-saving recovery in industrial and mining enterprises, agricultural water pumping and irrigation, distributed energy supply in urban and rural daily life, road traffic lighting, etc.) Take advantage of new hotspots. However, the strong interaction mechanism among wind turbine flow field parameters, structural dynamic parameters, and generator output parameters seriously restricts the service life and output power improve...

Problems solved by technology

Due to the lag in the development of technologies such as wireless rotating telemetry equipment and high-frequency flow field cameras, there is still no complete synchronous monitoring method and system for flow field parameters, structural dynamic parameters, and generator output parameters in wind turbines.
