Description
пр жени 4, блок 5 формировани производной тока ротора, ограничитель минимального возбуждени 6, суммирующий усилитель 7, инвертирующий усилитель 8 и логический элемент 9.strand 4, unit 5 forming the derivative of the rotor current, the minimum excitation limiter 6, the summing amplifier 7, the inverting amplifier 8 and the logic element 9.
Устройство работает следующим образом.The device works as follows.
Вне зоны действи ограничител минимального возбуждени 6 отрицательный сигнал производной тока ротора с выхода блока 5 через логический элемент 9 поступает на суммирующий усилитель 7.Out of the zone of minimum excitation 6, the negative signal of the derivative of the rotor current from the output of block 5 through the logic element 9 is fed to summing amplifier 7.
При переходе синхронного генератора в режим недовозбуждени , в зоне действи ограничител минимального возбуждени 6 логический элемент 9 подключает к суммирующему усилителю 7 положительный сигнал производной тока ротора с заданным коэффициентом усилени . При этом обеспечиваетс устойчивость в пределах значительной части коэффициентов Ki н по отклонению и производной частоты напр жени , реализуемых в устройстве.When the synchronous generator goes into the under-excited mode, in the zone of action of the minimum exciter 6, the logic element 9 connects to the summing amplifier 7 a positive signal of the derivative of the rotor current with a given gain factor. In this case, stability is provided within a significant part of the coefficients Ki n by the deviation and the derivative of the voltage frequency realized in the device.
При «качани х ротора генератора, сопровождающихс кратковременным действием ограничител -минимального возбуждени , ерабатывание логического элемента 9 может быть блокировано, например, выдержкой времени на срабатывание.With oscillations of the rotor of the generator, accompanied by the short-term action of the limiter-minimum excitation, the operation of the logic element 9 can be blocked, for example, by delaying the response time.
Устройство дл автоматического регулировани возбуждени синхронных генераторов измен ет воздействие гибкой обратной св зиA device for automatically controlling the excitation of synchronous generators changes the effects of flexible feedback
