摘要
为了提升瓦斯电厂汽轮机运行的稳定性,以H瓦斯电厂的1000 MW汽轮机为例,根据汽轮机低压转子相关参数构建出相应的有限元模型,然后以此为基础,分别对低压转子的模态频率及模态振型进行模拟分析,以此寻找出低压转子中存在的不足之处,为后续低压转子的优化设计提供支持。最后,通过实践应用对优化后低压转子的应用效果予以验证。通过实践应用可以发现,优化后的低压转子性能更加良好,出现损伤的概率更低,有利于提升整个汽轮机运行的安全性与稳定性。
In order to improve the stability of steam turbine operation in gas power plants,a finite element model is constructed based on the relevant parameters of the low-pressure rotor of the steam turbine in a 1,000 MW steam turbine of the H gas power plant as an example,and the modal frequencies and modal shapes of the low-pressure rotor are simulated on the basis of the model to find out the inadequacies of the low-pressure rotor,which will provide support for the optimal design of the low-pressure rotor in the future.This will provide support for the subsequent optimisation of the low pressure rotor design.Finally,the application effect of the optimised low pressure rotor is verified through practical application.It is found that the optimised low-pressure rotor has better performance and lower probability of damage,which is conducive to improving the safety and stability of the whole turbine operation.
