摘要
标准GB/T 8117.1-2008/IEC 60953-1:1990对汽轮机性能试验结果的修正提出了两种修正方法:用热平衡计算修正和用制造厂提供的修正曲线修正。综合分析近年研究成果,优选高精度等效热降模型,并对加热器端差、抽汽压损定量分析模型进行了完善,给出了编制修正曲线的计算公式,并就N600-24.2/566/566型600MW超临界机组及类似热力循环的机组给出了修正计算公式及修正计算结果。
There are two methods for eorreting calculating for steam turbine performance test, one method is by heat balance calculating,the other method is by using the correting curves. By analysing the papers on this subject, the high precision equivalent enthalpy drop method correcting model is choosed and the models for heaters calculation are improved , the correcting calculating method is provided. As an example, the corrrecting curves calculating process and results for a supercritical N600- 24.2/566/566 unit and the similar cycles are presented.
