摘要

以大同第二发电厂 2 0 0MW汽轮机通流部分改造性能试验的一类修正 (系统修正 )计算为例

说明采用等效热降法与采用ASME/ANSIPTC6A - 1982规定进行的一类修正具有良好的一致性。在分析单一因素偏离额定工况对整个机组的影响时

等效热降法更显出很高的优越性

Abstract

Taking the first class correction (system correction) calculation of performance test after retrofitting flow passage of a 200MW steam turbine at Datong Power Plant No.2 as example

the good consistency of using equivalent heat-drop method with above-mentioned first class correction carried out according to stipulations in ASME/ANSIPTC6A-1982 has been illustrated. When the influence of single factor having departure from the rated condition upon the entire unit is going to be analysed

the advantage of equovalent heat-drop method should be even obvious.
