METHOD FOR DETERMINING NUCLEAR-REACTOR POWER VARIATION PERIOD Russian patent published in 2002 - IPC

FIELD: control and protection systems of nuclear reactors. SUBSTANCE: for smoothing down input signal fluctuations this signal is converted into digital code; number of current values of digital codes is found from formula , where K is number of current values of digital codes; T_h.k is given high value of period; τ is given value of time step length; D is peak-to-peak amplitude of digital code fluctuations; Yi is current value of digital codes; averaged value of current digital codes is found from formula , where B is averaged value of current digital codes; Xi is time-step number varying between 1 and K and corresponding to number of digital-code current value; Yi is current value of digital codes; K is number of current values of digital codes; then power variation period of nuclear reactor is calculated from formula , where T is reactor power variation period; τ is given time-step length; B is averaged value of current digital codes. EFFECT: enhanced accuracy and speed. 2 dwg
