| In recent years, the direct air cooled technology development of our countryeach large-scale thermoelectric power station is swift and violent, regional largecapacity air cooler systems also put into operations, the thermal power plant is notonly the capacity wealthy and powerful family, is the consuming energy wealthy andpowerful family. As electrical power system marketization reform unceasingthorough as well as large increase of unit capacity, competitions among variouspower generation firms even more will be obvious, is also getting higher and higherregarding the request of production cost, only then through the fine refined theoperation and management of production and science, can the reducing productioncost, thus enhances the enterprises’ competitiveness. Therefore, various firepowerand CHP power plant must improve the efficiency that through varioustechnological means the unit operates, the operational hot efficiency is by theoperational factor comprehensive reflection, the fit and unfit quality of theseparameter operations are not only related with the design performance as well as thefuel characteristics of equipment, depends on the operational method of unit in thegreat degree as well as operates the technical level of operator.As a result of increase and enhancement of operational factor air cooling steamturbine unit capacity, improves its cost-effectiveness operation became a keyquestion of urgent solution. Now the technology and computer control developmentof large-capacity thermal power unit are swift and violent, take the Inner Mongoliaarea already the putting into operation air cooling steam turbine as the object ofstudy, applies the current analysis of energy saving algorithm, through computationsas well as analyses to its energy consumption Indices, determines during unitoperation the distributions and sizes of various energy consumptions, and analyzesunder its main operational factors, the operational methods as well as variousoperating modes the influence emphatically to the unit energy consumption, thus realized the unit under various varying operation modes still to operate in theoptimal condition, raised the running benefit.This article take the Anshan thermal power plant two300MW direct air cooledunit as the object of study, under the power plant existing measuring pointarrangement condition and the precision condition, uses the more advanced energyconservation analysis computational method, carries on the real-time quantitativeevaluation to the unit energy consumption condition, system analysis unit’s mainmovement parameter as well as to unit movement energy consumption influencesize and change tendency, thus provides the science for unit’s optimized movementto have the basis instruction.Indicated through the system movement practice, notonly this system may real-time monitor the Anshan thermal power plant two directair cooled units the energy consumption distribution condition, according to theabove moreover can real-time act according to each item to be able to damage thedeviation to diagnose the current unit hot efficient fit and unfit quality, themovement attendant carries on the adjustment, thus the realization unit’s securityand the highly effective movement, caused the Anshan thermal power plant theenergy conservation to fall consumes the level to get up a new stair. |
