In practical operation of 1000 MW pressurized-water reactor in nuclear power stations of China
the PID regulation with single impulse is adopted for regulation of water-level in the deaerators
but along with the proposal of requiring nuclear power station to participate into load regulation of the power grid
this single impulse regulation system is unable to make the water-level in the deaerator for perfectly satisfying the requirements of load adjustment in nuclear power stations.In order to enhance the suitability of water-level in the deaerator to the variation of load
a digitalized control system of the deaerator with three main impulses has been studied and designed
and through test on the emulation machine of nuclear power
the feasibility and effectiveness of said system design being verified.
