Research and development of a high-quality thermal-stress online monitoring model for the 600 MW turbine

ZHANG Hengliang, XIE Danmei, XIONG Yangheng, SUN Kunfeng

Frontiers in Energy 2007, Volume 1, Issue 3,   Pages 322-326 doi: 10.1007/s11708-007-0047-1

Abstract: To monitor and control its thermal state, a rotor s temperature and thermal stress fields must be calculated in real time. After some reasonable assumptions and simplification, iterative models of the rotor s temperature and thermal stresses were obtained with an integral transform based on a two-dimensional axis-symmetry thermal conduction differential equation. The models can deal with some nonlinear factors such as material and boundary condition. An example is given to compare results computed by the finite element method (FEM) and one-dimensional models. The result shows that the analytical model gained has high quality and the computing course is very short. The iterative formulas could be used not only to analyze the rotor’s thermal states of turbine, but to monitor and control them online. The method adopted can be used to analyze the thermal state of other axis-symmetry objects having similar boundary conditions.

The design and practice of giant hydro turbine generating units of Three Gorges ProjectShao Jianxiong

Shao Jianxiong,Liu Jingwang,Yuan Dafu

Strategic Study of CAE 2011, Volume 13, Issue 7,   Pages 104-110

Abstract:

In view of the specified design conditions of Three Gorges Project (TGP), the main technical problems that should be considered in the design of hydro turbine generating units are analyzed. The key technical researches performed are summarized and the parameters of hydro turbine generating units are optimized through the study on key technical problems. The unit operation results indicate that the performance of the hydro turbine generating units is excellent, and the units can operate in a safe, stable and highly efficient mode for a long term. Therefore, it is verified effectively that the general technical design of giant hydro turbine generating units is scientific and rational.
