根据一系列热力性能试验数据，分析了上海汽轮机厂生产的引进型３００ＭＷ汽轮机优化后的性能状况，指出在有些试验中存在的问题，并对评价机组性能的主要指标进行了讨论和分析，认为在目前机组出力余量偏大的情况下，习惯上延用的性能考核及评价方法不尽合理。表２
According to a series of thermodynamic performance test data, the optimized performance of imported 300MW steam turbine produced by Shanghai Steam Turbine Factory is analyzed. Some problems existing in some tests are pointed out. The main indexes for evaluating unit performance are discussed and analyzed. At present, the unit output margin is too large, the customary extension of the performance appraisal and evaluation methods are not reasonable. Table 2
