Description
Technical Field
The invention relates to the field of wind turbine generators, in particular to an intelligent protection device of a cooling and lubricating system, a turbine generator and a protection method thereof.
Background
The cooling and lubricating system of the wind turbine generator gear box must ensure forced lubrication of moving parts in the gear box, and filter and radiate oil, and consists of an electric pump, a filter device, a mechanical pump, an oil-air cooler, a pressure sensor, a connecting pipeline and the like.
Most gearboxes in the industry currently use temperature control valves and are tired to cope with a change once in 2 years, and for owners with larger volumes, the more troublesome is, and the time for changing all fans once is very long. In addition, the individual machine position temperature control valves are frequently started and stopped, the service life period is shortened, and the defects caused by the temperature control valves are effectively avoided by continuing one set of scheme in the industry.
The electric pump and the mechanical pump of the gear box cooling and lubricating system supply oil to the system at the same time, and the lubricating oil is filtered by the oil filter and then reaches the temperature control valve, and the temperature control valve automatically controls the flow direction of the lubricating oil according to the temperature of the lubricating oil. When the temperature of the passed lubricating oil is lower than 45 ℃, the lubricating oil directly enters the gear box; when the temperature of the passed lubricating oil is higher than 45 ℃, the valve core of the temperature control valve starts to act, and part of the lubricating oil directly enters the gear box and part of the lubricating oil enters the gear box through the cooling system; when the temperature of the passed lubricating oil is higher than 60 ℃, the valve core of the temperature control valve is completely closed, and the lubricating oil at the moment completely passes through the cooler to be cooled and then enters the gear box.
In practical application, the temperature control valve does not respond exactly as theoretically required, and the reason analysis of the high oil temperature of the gearbox between 5 years of 10 wind fields is adopted to obtain: most of the units reporting the high fault of the oil temperature are caused by the fact that the temperature control valve fails to operate normally, so that the high-temperature hot oil does not pass through the cooling fan.
Meanwhile, the temperature control valve belongs to a vulnerable and consumable part, has definite service life, the opening and closing action times are 30000 times, and according to the use experience of a wind field, the temperature control valve needs to be replaced in more than 2 years, so that maintenance and replacement cost is increased, and if the temperature control valve is not replaced, the operation efficiency of a fan and the service life of a gear box can be influenced.
In view of the above background, it is desirable to design a solution that can ensure that the gearbox has a suitable amount of lubrication and cooling oil, regardless of whether the thermo-valve is operating normally or not.

The method for protecting a follow-up cooling and lubricating system of a gearbox of a wind turbine generator according to claim 1, wherein in the step 2), when T1 is less than 20 ℃, the processor conducts the inlet end and the second outlet end to make part or all of the lubricating oil pass through the direct return pipeline, and the control strategy of the processor is as follows:
when T1 is less than 20 ℃ and T2 is less than 45 ℃, the conduction ratio of the inlet end to the second outlet end is 3/3 full-on;
When T1 is less than 20 ℃, T2 is more than or equal to 45 ℃ and less than 60 ℃, the conduction ratio of the inlet end and the second outlet end is 2/3;
When T1 is less than 20 ℃ and T2 is more than or equal to 60 ℃, the conduction ratio of the inlet end to the second outlet end is 1/3.
3. The protection method of a follow-up cooling and lubricating system of a wind turbine gearbox according to claim 1 or 2, wherein the cooling and lubricating system further comprises a temperature control valve arranged in front of an inlet end of a three-way electromagnetic proportional valve, and a first output end of the temperature control valve is used for partially or completely outputting lubricating oil with higher temperature; the second output end of the temperature control valve is communicated with the direct return pipeline and is used for partially or completely outputting lubricating oil with lower temperature;
the inlet end of the three-way electromagnetic proportional valve is communicated with the first output end of the temperature control valve through a pipeline, the first outlet end of the three-way electromagnetic proportional valve is communicated with a cooling pipeline, and the second outlet end of the three-way electromagnetic proportional valve is communicated with a direct return pipeline behind the second output end of the temperature control valve through a pipeline.
