Изобретение относитс к электротехнике , в частности к устройствам вклочени синхронных генераторов на параллельную работу и может быть использовано при синхронизации генераторов переменного тока, вход - н(их в состав передвижных электроагрегатов и электростанций, в частности генераторов частотой 400 Гц.The invention relates to electrical engineering, in particular, to devices for connecting synchronous generators to parallel operation and can be used to synchronize alternators and input devices (they are part of mobile electrical units and power plants, in particular, 400 Hz generators.
Известны устройства синхронизации , в которых определение момента включени осуществл етс путем сравнени приращени разности фаз за дискретшле промежутки времени текущим значением разности, фаз П.Synchronization devices are known in which the determination of the moment of switching on is carried out by comparing the increment of the phase difference over a discrete time interval by the current value of the difference, phase P.
Недостатком этих устройств вл етс низка точность при близкой к нулю разности частот синхронизируемых напр жений, сложность и недостаточна надежность, обусловлениые необходимостью большого объема вычислений.The disadvantage of these devices is low accuracy at close to zero difference in the frequencies of synchronized voltages, complexity and lack of reliability due to the need for a large amount of computation.
Наиболее близким по технической сущности к изобретению вл етс Устройство дл автоматической синхронизации с посто нньм временем опережени , содержащее формирователи пр моугольных импульсов, включенные на входы фазового компаратора, два счётчика импульсов, включенные на входы фазового компаратора, и сравнени . Кроме того, устройство соде1 кит RS-триггер, две логических схемы И, включенные на; пр мой и инверсный выходы триггера, вторые входы логических схем И присоединены к одному из формирователей пр моугольных импульсов, эходы фазового RS-триггера подк1вочены к фазовому к жпараts тору, причем выходы логических схем И подключены к счетным входам счетчиков импульсов, выходы которых включены ко входам схем сравнени 2.The closest to the technical essence of the invention is a device for automatic synchronization with a constant lead time, containing square pulse shapers connected to the inputs of a phase comparator, two pulse counters connected to the inputs of a phase comparator, and a comparison. In addition, the device contains a RS-trigger, two AND logic circuits included in the; the direct and inverse outputs of the trigger, the second inputs of logic circuits AND are connected to one of the formers of rectangular pulses, the outputs of the RS phase trigger are connected to the phase inputs of the output generator comparison circuits 2.
