Characteristics and Operation Issues of 1 000 MW Steam Turbines within Jiangsu Province

Two types of 1 000 MW ultra-supercritical steam turbines installed within Jiangsu Province are analyzed in this paper.The differences between the structural features and performance design parameters of these two types of steam turbines are introduced firstly,and then the root reasons leading to the deviation between the actual performance and initial design parameters are analyzed qualitatively.This paper can provide valuable reference for the type-selection of steam turbines as well as the operation and reform of power units in service.
