    Hunan Dazhuang First Science and Tech Limited Submits Chinese Patent Application for Temperature Abnormity Early Warning for Water Cooling System of Wind Turbine Generator

    November 16, 2022 - Electrical Patent News


      Beijing, Nov. 16 -- Hunan Dazhuang First Science and Tech Limited has submitted a patent application for temperature abnormity early warning for water cooling system of wind turbine generator. This invention was developed by Li Zhijin, Wen Wen, Jiang Xin, Ding Wei, Wang Fei and Zhou Honggui.

      The patent application number is CN202111281419 20211101. The patent publication number is CN114202096 (A). 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."
