Real-time calculation of coal consumption rate and error analysis

Combining with the Coal Management Information System of Qinhuangdao Cogeneration Power Plant, this paper analyzed in de-tail the real-time calculation of coal consumption rate and the programming method, summarized the main factors affecting coal consumptionrate and all kinds of causes leading to errors, discussed the choice of calculation cycle, preprocessing and interface of data as well as theclean-up and maintenance of database etc. related problems when this method was put into practice, and finally afforded concrete realizationsuggestions. The practical application shows that, this method is reasonable and feasible and is good for generalizing.
