Description
от значени зоны нечувствительности ус лител . После нелинейного элемента с выбранными параметрами сигнал поступает на регул тор, который воздействует на сервопривод исполнительного механизма, измен в зависимости от знака сигнала расход питательной воды, поступающей в барабан парогенератора.on the value of the dead zone of the suppressor. After the nonlinear element with the selected parameters, the signal is fed to the regulator, which acts on the actuator servo, changing, depending on the sign of the signal, the flow of feed water entering the steam generator drum.
Таким образом, предложенна система позвол ет надежно стабилизировать уровень воды в барабане парогенератора путем увеличени чувствительности регул тора при больших отклонени х регулируемой величины и уменьшени дисперсии отклонени уровн и позвол ет уменьшить число аварийных ситуаций, св занных ,с упуском воды из барабана или забросом ее в пароперегреватель парогенератора, а также позвол ет повыситьThus, the proposed system allows to reliably stabilize the water level in the steam generator drum by increasing the sensitivity of the regulator with large deviations of the controlled value and reducing the dispersion of the level deviation and allows reducing the number of emergencies associated with dropping water out of the drum or throwing it into steam superheater, and also allows you to increase
долговечность системы управлени благодар уменьшению числа срабатываний,the durability of the control system due to the reduction in the number of operations,
Ф о р м у л а изобретени F o rmu l invention
Система регулировани расхода питательной воды в парогенераторе, содержаща дарчик стабилизируемого параметра, подключенный через последовательно соединенные сул матрр и нелинейный элемент ко входу регул тора с серводвигателем, отлича. ю - щ а с тем, что, с целью повышени качества регулировани нелинейный элемент выполнен в виде усилител с зоной нечувствительности и с насыщением.The system for regulating the feedwater flow rate in the steam generator, containing a gary of the parameter to be stabilized, connected through a series-connected sul matrr and nonlinear element to the regulator input with a servomotor, is different. so that, in order to improve the quality of regulation, the nonlinear element is designed as an amplifier with a dead band and with saturation.
