Embodiment 1

[0057] Embodiment 1 of the present invention is described as follows:

[0058] 1) When the air path of the gearbox radiator is blocked by catkins;

[0059] 2) The acquisition module collects the figure 1 The real-time operation data of each measuring point and the working status of the fan motor and oil pump motor, and through figure 2 The system shown passes real-time operational data to the analysis module;

[0060] 3) The analysis module found by comparing with the heat dissipation model that within a certain period of time, the temperature difference between the temperature T2 and the temperature T4 was continuously smaller than the minimum warning value, and an early temperature anomaly occurred;

[0061] 4) The analysis module monitors the working status of the oil pump motor and the fan motor to be normal, and eliminates the fault of the motor;

[0062] 5) The analysis module simultaneously monitors the oil flow Q1, Q3, and Q4 to be normal, and eliminates faults suc...

Embodiment 2

[0066] Embodiment two of the present invention is described as follows:

[0067] 1) First, establish the flow model of the temperature control valve through the theoretical analysis of the design, and complete the calibration of the model through the factory test and on-hook test, and store the parameters in the system analysis module;

[0068] 2) When the fan is running, the acquisition module monitors the pump outlet flow Q1, the distributor branch flow Q3, the radiator branch flow Q4 and the oil temperature T2 behind the filter element in real time, and transmits the data to the analysis module;

[0069] 3) The analysis module inputs the operating data into the model established in the previous stage for analysis and comparison, and obtains the deviation value of the operating data;

[0070] 4) According to different deviation values, the action module takes different actions: when the deviation is within 10%, the temperature control valve is in normal state and no action i...

Abstract

The invention discloses an intelligent fault early warning system and method of a gear box lubricating cooling system and a wind generating set, and belongs to the field of wind generating sets. The lubricating cooling system comprises an oil pump, a filter, a temperature control valve, a radiator, a distributor, an analysis system, a sensor M1, a sensor M2, a sensor M3, a sensor M4 and / or a sensor M5; wherein the oil pump, the filter, the temperature control valve, the radiator and the distributor are sequentially connected through an oil channel pipeline, and the branch output end of the temperature control valve is connected to the position, between the radiator and the distributor, of the oil channel pipeline through a three-way pipe; and the analysis early warning system is used for collecting, analyzing and judging data of the sensor M1, the sensor M2, the sensor M3, the sensor M4 and / or the sensor M5, and targeted warning is carried out according to judged results. According tothe intelligent fault early warning system and method of the gear box lubricating cooling system and the wind generating set, the fault early warning system is used for real-time monitoring the gear box lubricating cooling system, and used for carrying out automatic maintenance according to requirements or real-time fault diagnosis and early warning; and the problems that early faults of the gearbox lubricating cooling system of the wind generating set are difficult to be found out, and causes of the faults cannot be located are solved.

Description

technical field [0001] The invention relates to the field of wind turbines, in particular to an intelligent fault warning system for the lubrication and cooling system of a gearbox of a wind turbine, its method and the unit. Background technique [0002] The gearbox is the core component of the double-fed and semi-direct drive wind turbines, and the gearbox lubrication and cooling system is an important subsystem to ensure the normal operation of the gearbox. [0003] The abnormality of the lubrication and cooling system of the gearbox during the operation of the wind farm is one of the main causes of failure. However, the monitoring methods for the abnormality of the lubrication and cooling system of the gearbox in operation are very limited. Mainstream products all use one pressure sensor, one pressure switch, one differential pressure switch or two pressure sensors, one differential pressure switch arrangement, which can only send out an alarm or shutdown signal when the ...
