摘　　要：针对SIS系统火电厂多机组负荷经济分配的要求,从单元机组锅炉和汽轮机设计计算书或性能考核试验数据出发,结合单元机组实时性能计算和耗差分析的原理,提出了一种可以同时解决机组负荷特性线的获取和机组负荷特性线的实时修正问题的火电厂多机组负荷经济分配的方法。该方法计算简捷、实时性强,在获得负荷优化分配结果的同时,给出了负荷优化分配的准确效果。To the desire of load economic assign in the supervisory information system （SIS） for a coal-fired power plant,a method solving the problem , which at one time treat how to acquire the representative load characteristic curve of each power station and how to revise the curve on real time, is proposed. It is educed from the boiler and steam turbine designing data or performance assess experiment data, following the principles of real time pedormance calculation and efficiency loss analysis to a unit power station. It shows simple calculation process and high calculation efficiency, and gives the exact effect of load optimizing assign when obtaining the load optimizing assign results.
