APPROACH TO SOME PROBLEMS REGARDING DYNAMIC CHARACTERISTICS CALCULATION OF STEAM TURBINE GOVERNING SYSTEM
After comparing experimental result and theoretical calculation
some disputable problems such as the time constant of relay
the axial force of pilot valve and the shut-down speed of servo-motor are approached
referring to the evaluation of dynamic characteristics of the governing systems on N125 and N300 steam turbines. Other problems are as well discussed as follows;the simplification of math models in calculating dynamic characteristics; the changes of system structure and disturbing amplitude in using electro accelerator; the variation and deterioration phenomena of dynamic parameters of math models; and the importance of carrying the experimental research of system identification
