The invention provides a cooling state evaluation and early warning method for a water cooling system of a wind turbine converter, comprising the following steps: using a data acquisition and monitoring control system to obtain real-time data of variables representing the cooling state of the water cooling system of the converter; preprocessing the real-time data Then input it into the cooling state evaluation and early warning model of the water-cooling system of the wind turbine converter, and calculate the predicted value of water temperature and water pressure at the water inlet of the water-cooling system of the converter; Evaluate the cooling status of the converter water-cooling system, and obtain the first, second, third, and fourth scores, as well as the overall score; provide fault warning for the cooling status of the converter water-cooling system; predict the occurrence time of faults and generate maintenance suggestions . The invention can solve the technical problem that when the cooling state of the converter water cooling system is evaluated, the changing process and trend of the cooling state of the water cooling system are not monitored, and the technical problem can only be passively evaluated and has no early warning function.
Description
technical field [0001] The invention relates to the technical field of wind turbines, in particular to a cooling state evaluation and early warning method for a water-cooling system of a converter of a wind turbine. Background technique [0002] There are many electrical components in the converter cabinet of the wind turbine, and the temperature has a great influence on the working characteristics of the converter. With the increase in the altitude of the installation location of onshore wind turbines and the development of offshore high-power wind turbines, the requirements for the heat dissipation capacity of the converters in the wind turbines also increase. Air-cooled converters cannot meet the harsh environment and high-power wind turbines, and water-cooled converters have become the mainstream of such wind turbines. The water-cooled converter has a water-cooling system to dissipate heat from the converter, so the cooling state of the converter’s water-cooling system ...
