摘　　要：引入加热单元和虚拟热力系统的概念,首次构建了适宜于汽轮机热力性能试验能耗定量分析使用的计算模型,只需利用试验所安装的测点,就能精确计算高压加热器系统内局部扰动对热经济性指标的影响。模型具有通用、精确和适应计算机程序化的特点,适宜于汽轮机热力性能试验定量分析使用。实例验证了方法的有效性。The concepts of heating unit and virtual thermal system are introduced in constructing the calculating model of quantitative analyzing for energy consumption in thermal performance test of steam turbine for the first time. The effect on the thermo - economic index caused by the inner turbulence of the high pressure heater system can be accurately calculated only by applying the parameters acquired by measuring points. The model has the characteristics of versatile, accurate and suitable for computerization. It is fit for the quantitative analyzing in performance test of steam turbine. An example is given to illustrate the validity of this method.
