The invention relates to a state monitoring method and system of a water-turbine generator set, computer equipment and a computer storage medium. The state monitoring method of the water-turbine generator set comprises the steps that when the bearing temperature of the water-turbine generator set is abnormal, the current oil temperature of circulating oil and the current water temperature of cooling water in the water-turbine generator set at the present moment are respectively obtained, and the first flow rate of the circulating oil and the second flow rate of the cooling water at the presentmoment are read respectively; the first heat emitted from the circulating oil is calculated according to the initial oil temperature, the current oil temperature and the first flow rate of the circulating oil, and the second heat absorbed by the cooling water is calculated according to the initial water temperature, the current water temperature and the second flow rate of the cooling water; andif the first heat is higher than the second heat, the flow rate of the cooling water of the water-turbine generator set is increased, and if the first heat is lower than the second heat, the flow rateof the circulating oil of the water-turbine generator set is increased. The monitoring real-time performance of the water-turbine generator set can be improved, and the corresponding monitoring effects are improved.
Description
technical field [0001] The invention relates to the technical field of equipment automation management, in particular to a state monitoring method and system, computer equipment, and computer storage medium of a hydroelectric generating set. Background technique [0002] With the development of the electric power industry, the theory of reliability engineering has gradually been introduced into the electric power industry, and the reliability of power system has also emerged as the times require, which has become an important means for the electric power industry to obtain significant economic benefits. At present, it has penetrated into power system planning, design, manufacture, construction and installation, operation and management, and has been widely used. How to monitor the hydroelectric generating set and ensure its reliability in the operation process comes from this. [0003] Traditional schemes usually require regular testing of the hydro-generator set and corres...
