Abstract

The invention relates to the field of wind driven generator detection, in particular to a method for detecting the health state of a wind meter of a wind driven generator, and the method comprises the following steps: S1, obtaining SCADA data, and filtering the data; S2, carrying out preprocessing on the filtered data; S3, constructing a health scoring index and a discrimination standard of the wind meter; and S4, analyzing the health state of the wind meter according to the collected data. The method has the advantages that the health condition monitoring cost of the wind meter of the fan is low, the potential is large, SCADA monitoring data are fully utilized, the intelligence, automation and real-time performance of detection are achieved, in addition, a data preprocessing scheme is provided, the correlation between the wind meter wind speed and the wind meter tower wind speed is guaranteed, the relation between the wind meter wind speed and the wind meter tower wind speed is more clearly presented, and meanwhile, the thought of the invention can be extended to the detection of more fan equipment components, and has great significance in the detection of the whole fan equipment.

Description

technical field [0001] The invention relates to the field of detection of wind power generators, in particular to a method for detecting the health status of anemometers of wind power generators. Background technique [0002] A main source of the wind speed measurement data of the wind turbine is the anemometer of the wind turbine (wind generator) itself. Due to the influence of working years, various natural environmental factors, and the wake generated by the blades of other fans in the wind field, the anemometer of the fan itself will have certain errors in its measurement accuracy, which will undoubtedly lead to the system using the measured There is a corresponding deviation between the power generation calculated by the wind speed value and the actual power generation. The existing technology generally adopts the method of manually repairing the faults of the anemometers of the wind turbines in the wind field on time to reduce the error when the anemometers measure th...
