International Patent Classification codes are G06Q10/04, G06Q10/06, G06Q50/06, H02M1/00 and H05K7/20. Cooperative Patent Classification codes are G06Q10/04 (CN), G06Q10/0639 (CN), G06Q50/06 (CN), H02M1/00 (CN), H05K7/20927 (CN), H05K7/20945 (CN), Y02A90/10 (EP) and Y02E10/76 (EP).
An abstract released by the State Intellectual Property Office of China states: "The invention relates to the technical field of wind power, and discloses a wind turbine generator set water-cooling system temperature abnormity early warning, which comprises the following steps: collecting monitoring data of a wind turbine generator set converter water-cooling system, selecting characteristic parameters related to the temperature of the converter water-cooling system, cleaning abnormal values such as null values and zero values in the monitoring data, and carrying out early warning on the abnormal temperature of the converter water-cooling system. Linear interpolation is adopted for filling, and different characteristic parameters are analyzed; all wind driven generators in the same wind power plant are divided into a plurality of wind driven generator sub-clusters according to geographic positions and altitude distribution, and for each wind driven generator sub-cluster, characteristic parameters of a wind turbine generator converter water cooling system running in the sub-cluster are analyzed. The wind turbine generator water cooling system temperature abnormity early warning is beneficial for operation and maintenance personnel to reasonably adjust operation and arrange a maintenance plan, effectively reduces electric quantity loss caused by fault shutdown, and maintains stable operation of a power grid."
