100 MW熔盐塔式太阳能热发电站中汽轮机主蒸汽参数选择的对比分析

COMPARATIVE ANALYSIS OF MAIN STEAM PARAMETERS SELECTION OF STEAM TURBINES FOR 100 MW MOLTEN SALT TOWER CSP STATION

太阳能热发电站中汽轮机主蒸汽参数的选择对此类电站的经济性起着至关重要的作用,是决定此类电站投资额及系统运行状况的关键参数。以国内某汽轮机主机厂提供的相关数据为依据,并结合国内太阳能热发电站的设计经验,对甘肃省某100 MW熔盐塔式太阳能热发电站中汽轮机主蒸汽参数(主蒸汽压力和主蒸汽温度)的选择进行了简要的对比分析,并针对主蒸汽参数的选取进行了推荐,以期为熔盐塔式太阳能热发电站的设计提供参考。

The selection of main steam parameters of steam turbine is very important to the economy of CSP station,and it is the key parameter to determine the investment quota and system operation status of this kind of power station.In this paper,based on relavant data provided by a domestic steam turbine OEM,combined with the design experience of domestic CSP station,a brief comparative analysis of the selection of main steam parameters(main steam pressure and main steam temperature)of steam turbine in a 100 MW molten salt tower CSP station in Gansu Province,and the recommended main steam parameters are obtained,which can provide reference for the design of molten salt tower CSP station.
