Problems solved by technology
[0004] However, the overheating of the winding does not necessarily mean that there is a generator failure. In the case of full load power generation, the passing current heating will also lead to high temperature. At the same time, the temperature is affected by the ambient temperature, resulting in large changes in the winding temperature in different seasons and different periods.
The way of over-temperature alarm and shutdown is not conducive to the full utilization of wind energy, and it is easy to cause waste of wind resources

The invention discloses a detection system for a water chilling unit in an offshore wind farm. The detection system for the water chilling unit in the offshore wind farm comprises a U-phase temperature sensor, a V-phase temperature sensor, a W-phase temperature sensor, a power data sampler, a drive-end temperature sensor, a non-drive-end temperature sensor, a water inlet temperature sensor, a water outlet temperature sensor, an arithmetic unit and a data output display, wherein the U-phase temperature sensor, the V-phase temperature sensor, the W-phase temperature sensor, the power data sampler, the drive-end temperature sensor, the non-drive-end temperature sensor, the water inlet temperature sensor and the water outlet temperature sensor are connected with the arithmetic unit; and the arithmetic unit is connected with the data output display. According to the detection system for the water chilling unit in the offshore wind farm, which is disclosed by the invention, faults are determined according to the three-phase active power and the three-phase winding temperature of a fan generator, and the two-end temperatures of a drive shaft, the running condition of the fan generator can be accurately reflected, and the threshold value of fault shut-down can be accurately and scientifically controlled, thus the utilization rate of wind power resources is increased.
Description
technical field [0001] The invention relates to the field of wind power, in particular to a detection system for a water-cooled unit in an offshore wind farm. Background technique [0002] The wind turbine generator is one of the most important components of the wind power generation system. Identifying whether the wind turbine generator is malfunctioning is an important part of maintaining the wind turbine. [0003] Usually, each phase winding of the fan generator has a temperature sensor, and the driving end and non-driving end of the transmission bearing also have temperature sensors. The temperature sensors can collect the temperature of the water outlet and inlet water, and take preventive measures for high temperature conditions to maximize protection. Windings to ensure the safe operation of wind turbine generators. [0004] However, overheating of windings does not necessarily lead to generator failure. In the case of full load power generation, the passing current ...
