摘　　要：对于世界首台全高位布置汽轮发电机组,其主、辅机系统应用了诸多与常规布置机组不同的设计方案,包括主、再热系统,抽汽回热系统,排汽系统等。就新设计方案对机组热经济性造成的影响进行了逐一分析。结果表明,采用的新设计方案大多有利于机组热经济性的提高,全高位布置汽轮发电机组的热经济性总体上优于同参数的常规布置机组。For the world's first fully high-level arrangement steam turbine generator set,its main and auxiliary machine systems apply many different design schemes from the conventional arrangement unit,including the main and reheat steam system,regenerative steam extraction system,steam exhaust system,etc.The influence of the new design scheme on the thermal economy of the unit is analyzed one by one.The results show that most of the new design schemes can improve the thermal economy of the units.The thermal economy of the turbo-generator set with high position arrangement is generally better than that of the conventional one with the same parameters.
