Embodiment Construction

[0034] As shown in Figure 1 and Figure 2, the present invention proposes a digital steel ball coal mill simulation control method, including:

[0035] a. Select measurement points on the coal mill and obtain measurement data by means of measurement;

[0036] b. Based on the simulation control platform, through the realization of self-optimization of online simulation, the input measurement data is analyzed and calculated and accident prediction is carried out, the current working conditions and optimization are judged, and online decision-making control is carried out accordingly, providing a set of real-time optimal control information,

[0037] c. Use the control information to control the action of the actuator on the coal mill.

[0038] As shown in Figure 2, the signal required by the DMS is collected by the IO system (AI / DI data acquisition module) and becomes a digital signal, and becomes an available engineering unit signal through the input signal processing unit; und...

Abstract

A method for controlling coal grinder includes selecting measurement points on grinder and obtaining measured data, using artificial control platform to realize on line self optimizing for submitting out a set of optimum control policy on real time, applying said control information to control action of executing mechanism for coal grinder. A control system for realizing the method is also disclosed.

Description

technical field [0001] The invention relates to a control method and a control system of a digital steel ball coal mill. Background technique [0002] Steel ball coal mill is a pulverized coal preparation system (referred to as pulverization system) widely used in thermal power plants. It is the basic condition for the normal operation of the pulverizing system to adapt the output to each other. The pulverizing system is designed correctly and adjusted reasonably (the best operating condition is found through the adjustment test), and the parameters are strictly maintained during operation. The working condition can reach the best level, that is, the pulverizing output is the largest, and the energy consumption per unit weight of pulverized coal is the smallest. However, there are too many external disturbance factors in reality, such as complex changes in the raw coal type in the pulverizing system (influencing factors include grindability coefficient, moisture, etc.), the...
