The Research Of Operating Characteristic For 1000MW Ultra-supercritical Units

1000MW Ultra-supercritical power generating units is powerful and effective.On research of the units'feature , we can determine the performance of improving the thermal economy of the unit. It is meaningful to save energy and reduce consumption of the units.Based on experimental data of a 1000MW ultra-supercritical units, this paper determined the operating characteristics of the units and cleared the advantages and shortcomings by analysising the thermal efficiency of boiler units, steam turbine heat rate and so on. The conclusions of unit performance have been given. Analysised each main factors in affecting operating characteristics, the specific measures of improving the thermal economy are proposed.It provides reference for guiding safe and economic operation of ultra-supercritical generating units with operating characteristics of ultra-supercritical generating unit proposed on this paper.
