Abstract

The invention provides a method and device used for evaluating a fan blade de-icing investment plan. The method includes the steps that sample data of fan operation is obtained; according to the sample data, the icing generating capacity loss, caused by blade icing during power generation, of a fan is calculated; according to the sample data and pre-stored fan operation maintaining records, the shutdown generating capacity loss, caused by icing shutdown during power generation, of the fan is calculated; according to the icing generating capacity loss and the shutdown generating capacity loss,the total generating capacity loss, caused by blade icing, of the fan is calculated within a preset evaluating time period; according to a preset evaluating rule and the total generating capacity loss, the fan blade de-icing investment plan needing to be evaluated is evaluated, so that an evaluating result is obtained. With the method and device used for evaluating the fan blade de-icing investment plan, the fan blade de-icing investment plan can be rapidly and accurately evaluated without manual operation, so that the evaluating efficiency and evaluating precision are effectively improved.

Description

technical field [0001] The present invention relates to the technical field of data communication, in particular to a method and device for evaluating investment schemes for deicing fan blades. Background technique [0002] As one of the important power generation methods that are safe, reliable, pollution-free and can be connected to the grid, wind power has developed rapidly in recent years. In cold and humid areas, fan blades are prone to freezing, which will damage the aerodynamic performance of the blades, reduce the power generation efficiency of the unit, cause accelerated fatigue of components, and reduce service life. In severe cases, the fan will be forced to stop or even collapse, endangering personal safety Therefore, the problem of fan blade icing should not be underestimated. In view of the icing problem of fan blades, in order to reduce the loss of blade icing and improve the efficiency of blade deicing, it is necessary to evaluate and analyze the blade deici...
