Desulfurization system operation optimization method based on improved PSO-FCM algorithm

Abstract

The invention relates to a desulfurization system operation optimization method based on an improved PSOFCM algorithm. The method comprises the steps: carrying out the clustering of sample data through the improved PSOFCM algorithm, and building a desulfurization system operation target condition library; an ARIMA model is adopted to predict desulfurization boundary conditions; and guiding the adjustment of desulfurization operation parameters. Compared with the prior art, parameters such as pH, slurry density and the like closely related to desulfurization operation cost are considered simultaneously, the problem of dispatching of a dispatching circulating pump combining a variable frequency pump and a common fixed frequency pump of an existing power plant is solved simultaneously, multi-parameter synchronous adjustment can be performed, and the adjustment mode is more flexible. The traditional FCM algorithm is improved, aiming at the defects that the traditional FCM is greatly influenced by an initial clustering center, is easy to fall into local optimum and is uncertain in clustering number, the PSO algorithm is used for optimizing the traditional FCM algorithm, the local optimum can be avoided. Meanwhile, a clustering effectiveness evaluation function is introduced, and the clustering number with the best clustering effect can be determined.

Description

technical field [0001] This application relates to the field of data processing, in particular to a desulfurization system operation optimization method based on the improved PSO-FCM algorithm. Background technique [0002] SO2 is one of the main pollutants in the atmosphere. As a large coal-fired power unit in my country, it is the main source of SO2 emissions. Therefore, reducing SO2 emissions from thermal power plants is the focus of pollution control. [0003] Limestone / gypsum wet flue gas sulfur dioxide removal method is a SO2 removal technology commonly used in power plant boilers in my country. The purpose of desulfurization is achieved by injecting limestone slurry and chemically reacting with SO2 in the flue gas. According to my country's increasingly stringent environmental protection regulations, the desulfurization system needs to operate continuously, reliably and efficiently. However, while the desulfurization system reduces SO2 emissions from power plants and...

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
