Operation optimization method of desulfurization system based on improved pso-fcm algorithm

Abstract

This application relates to a desulfurization system operation optimization method based on the improved PSO-FCM algorithm. The method includes: using the improved PSO-FCM algorithm to cluster sample data, and establishing a desulfurization system operation target working condition library; using the ARIMA model to perform desulfurization. Predict the boundary conditions; guide the adjustment of desulfurization operating parameters. Compared with the existing technology, it takes into account the parameters closely related to the desulfurization operation cost, such as pH and slurry density, and solves the problem of regulating and circulating pumps in the combination of variable frequency pumps and ordinary fixed frequency pumps in power plants at the same time, and can perform multi-parameter synchronous adjustment , the adjustment method is more flexible. The traditional FCM algorithm is improved. In view of the shortcomings of the traditional FCM, which are greatly affected by the initial clustering center, it is easy to fall into a local optimum, and the number of clusters is uncertain. Using the PSO algorithm to optimize it can avoid falling into a local optimum. At the same time, the clustering validity evaluation function is introduced to determine the number of clusters with the best clustering effect.

AI Technical Summary

Problems solved by technology

Existing adjustment technologies are often only aimed at the adjustment of fixed-frequency pumps, without considering the impact of variable-frequency pumps on the entire system

[0008] (3) The traditional FCM algorithm needs to manually determine the initial cluster center and the number of clusters, which has great subjectivity and uncertainty, and the algorithm is easy to fall into local extremum

[0009] (4) Since the switching of the pump takes a certain amount of time, and parameters such as pH and slurry density have a certain time delay, it is difficult to apply the existing operation adjustment methods to the actual operation optimization adjustment
