Abstract:

Abstract:In order to improve the adaptability of thermal power unit to coal grades, the origional coordinate control system of the unit was optimized and adjusted.The advanced coal quality forecast control strategy was adopted to amend the coal quality. At the same time, the temperature control of the main steam and the logic parameters were optimized.After optimization, the unit can suit to coal grade variation, and the main parameters were controlled in beter level. The safe and stable operation of the unit was ensured.
