Description
ров поступает в блок 6, который н подает соответствующую команду на переключение регул тора 7 трансформатора. Положение регул тора 7, бывшее до его переключени , (фиксируетс блоком 8, и на логический элеjMenT «И подаетс соответствующий сигнал. Прн восстановленнн режима в сети и снижении контролируемых параметров-токов ротора н статора генератора-ниже максимальных длительно допустимых з)1ачеиий в блоке 3 формируетс соответствующий сигнал, который , суммиру сь в элементе «И с сигналом блока 8, обеспечивает поступление на блок 6 команды на возврат регул тора 7 в исходное положение. Последн снимаетс при исчезновении одного из входных сигналов элемента «И, т. е. при достижении одним из контролируемых параметров максимального длительно допустимого значени или при возврате регул тора 7 в исходное положение . Если в режиме перегрузки имела место индивидуальна разгрузка генератора с помощью блока разгрузки 4, то поступление сигнала на элемент «И из блока 3 блокируетс до возврата установочного устройства 2 АРВ в исходное положение.The ditch arrives at block 6, which n gives the appropriate command to switch the regulator 7 of the transformer. The position of the regulator 7, which was before its switching (fixed by block 8, and the logical element "the corresponding signal is given. The recovered network mode and the reduction of the monitored parameters of rotor currents on the stator of the generator — below the maximum long-term allowable g) 3, a corresponding signal is generated, which, summing up in the element "And with the signal of block 8", provides the receipt to block 6 of a command to return the regulator 7 to its initial position. The latter is removed when one of the input signals of the element "I" disappears, i.e., when one of the monitored parameters reaches the maximum permissible value or when the regulator 7 returns to its original position. If, in the overload mode, an individual generator unloading took place using the unloading unit 4, the signal to the And element from block 3 is blocked until the ARV fixer 2 returns to its original position.
