Embodiment Construction
[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0041] The block diagram of the thermal power plant mill load prediction method based on periodic rolling optimization of the present invention is as follows figure 1 As shown, the flow chart is as figure 2 shown. Taking a mill in a thermal power plant as an example, a specific application of the present invention is given. The mill model is DTM350 / 700, and the speed is 17.57r / min. DCS is used to realize the collection of mill input signals, the execution of algorithms, and other various operation monitoring functions. The system structure is as follows: image 3 shown. In the real-time control layer, it is composed of Siemens S7-400 and S7-200 series PLCs and their extended input and output modules, making full use of the advantages of S7-200 series PLCs such as low cost, easy expansion, and simple programming to real...
