单轴联合循环机组燃气轮机出力的评估方法

Evaluation Method for Power Output of Gas Turbine in Single Shaft Combined Cycle Unit

单轴联合循环机组由于燃气轮机、汽轮机共用一个发电机,难以区分燃气轮机和汽轮机的运行状况,给电厂判断机组运行状况带来一些困难。提出了一种通过汽轮机或燃气轮机的热平衡计算,来评估单轴联合循环机组燃气轮机出力和汽轮机出力的方法。通过该方法可以确定单轴联合循环中燃气轮机、汽轮机的运行状况,为机组运行和检修提供依据。

The gas turbine and steam turbine in the single shaft combined cycle unit share one generator,so it is hard to distinguish the operation conditions of gas turbine and steam turbine,which brings the power plant some difficulties to judge the operation conditions of the unit.Based on the heat balance computation of the gas turbine or steam turbine,a method of evaluating the power output of the gas turbine or the steam turbine in single shaft combined cycle unit was proposed.According to this method,the operation conditions of the gas turbine and steam turbine in single shaft combined cycle unit could be determined,which provided references for the operation and maintenance of the unit.
