| Abstract: | Three methods for raising main steam pressure stability on CCBF mode are put forward in this paper: increasing the steam turbine transfers that delay Doppler mapping action function,increasing equivalent main steam pressure model after the output of original main steam pressure setting point loop,increasing the dynamic forward loop of main steam pressure setting point-fuel flow,and finally giving the real effect of load going up and down the unit load and relevant data. |
