| Abstract: |
| An automatic coal blending system for power plant is developed based on the coal blending model according to the ratio rule. The system structure, coal blending model and ratio calculation are introduced. Its HMI is programmed with InTouch configuration software,the ratio is calculated with Matlab and the data exchange is done using DDE (Dynamic Data Exchange). Variable-frequency technology is applied to realize closed-loop regulation for optimal coal blending, which improves economical benefit of power plant. |
