[0074]

[0075]

[0076] The present invention adopts a multi-factor unit degradation evaluation algorithm with variable weight: the data integration technology of the evaluation data layer is used to uniformly process all kinds of evaluation data, and the evaluation data is integrated and input to the evaluation index layer to calculate the degree of deterioration of each index. At the same time, the weight parameters of each index are read, and the final weighted calculation obtains the overall health status of the unit and outputs it to the man-machine interface. The invention can carry out deterioration evaluation on the unit ...

Abstract

The invention discloses a hydroelectric unit variable weight degradation evaluation system and evaluation method. The system includes an evaluation data layer, an evaluation index layer, an evaluation algorithm layer and a human-computer interaction layer connected in sequence. The method is a multi-factor unit degradation evaluation algorithm with variable weight: the data integration technology of the evaluation data layer is used to process all kinds of evaluation data in a unified manner, the evaluation data is integrated and input into the evaluation index layer, and the degree of deterioration of each index is calculated. The weight parameters of each index are taken, and the final weighted calculation obtains the overall health status of the unit and outputs it to the man-machine interface. The invention can carry out deterioration evaluation on the unit in real time, provide on-line operation monitoring and state maintenance guidance. The present invention can provide an effective solution for the construction of the condition-based maintenance and degradation evaluation system of hydroelectric units in different hydropower plants, different periods and different states, and provide efficient and practical decision-making services for the degradation analysis of hydropower plant equipment, thereby providing reliable conditions for the development of condition-based maintenance. support.

Description

technical field [0001] The invention relates to the field of state evaluation of hydroelectric units, in particular to a hydroelectric unit variable weight degradation evaluation system and evaluation method. Background technique [0002] Hydropower units are affected by factors such as erosion, wear, and alternating stress during operation, and the performance of each component will gradually degrade with the increase of service time. The reliability of its equipment performance has an important impact on the safety and stability of the power grid. If a failure occurs, it may cause the unit to be shut down for maintenance, thereby disrupting the routine operation of the power plant, causing serious economic losses, and even catastrophic accidents such as grid disconnection. Therefore, change the traditional single passive maintenance mode, promote the development of hydropower unit maintenance to predictive maintenance, avoid catastrophic power grid accidents caused by hydr...
