采用落地轴承有利于提高某空冷600MW机组轴系的安全裕度

Improvement on Safety Margin of Rotor System of 600MW Air-Cooled Turbine Generator Set by Floor Pedestal

某空冷600MW汽轮发电机组是国内首台完全自主开发设计的全新机组,本文针对某空冷600MW汽轮发电机组低压转子采用落地轴承结构,对轴系安全裕度的影响进行了计算和分析。计算结果表明:采用落地轴承有利于提高某空冷600MW机组轴系的安全裕度。

The 600 MW air-cooled turbine-generator set is the first one developed by HTC in China. In this paper, the influence on security margin of rotor system was calculated and analyzed because LP rotor system of the 600 MW air cooled turbine-generator set adopted floor pedestal. The results indicate that the floor pedestal can improve the security margin of rotor system of the 600MW air cooled turbine-generator set.
