The invention provides a wind turbine generator converter water cooling system cooling state evaluation early warning method comprising the following steps: using a data acquisition and monitoring control system to obtain real-time data representing a variable of a converter water cooling system cooling state; preprocessing the real-time data, inputting the preprocessed real-time data into a windturbine generator converter water cooling system cooling state evaluation early warning model, and calculating to obtain a water temperature prediction value and a water pressure prediction value of awater inlet of a converter water cooling system; evaluating the cooling state of the converter water cooling system by combining the water temperature measured value and the water pressure measured value of the water inlet to obtain a first score, a second score, a third score, a fourth score and a comprehensive score; performing fault early warning on the cooling state of the converter water-cooling system; and predicting the fault occurrence time, and generating maintenance suggestions. The technical problems that when the cooling state of the converter water-cooling system is evaluated, the change process and trend of the cooling state of the water-cooling system are not monitored, only passive evaluation can be conducted, and the early warning function is not achieved can be solved.
Description
technical field [0001] The invention relates to the technical field of wind power generating sets, in particular to a cooling state evaluation and early warning method for a water cooling system of a converter of a wind power generating set. Background technique [0002] There are many electrical components in the converter cabinet of the wind power generating set, 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 high-power offshore wind turbines, the requirements for the cooling capacity of the converters in the wind turbines are also increased. 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 th...
