APPROACH TO SOME PROBLEMS REGARDING DYNAMIC CHARACTERISTICS CALCULATION OF STEAM TURBINE GOVERNING SYSTEM[J]. Thermal power generation, 1993, (1): 29-35.
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
