Abstract
Способ синхронизации и подключения в режим параллельной работы регулируемого статического источника переменного напряжения и источника переменного напряжения, заключающийся в том, что измеряют мгновенные значения выходных напряжений источников, формируют сигнал, пропорциональный разности фаз выходных напряжений источников, по которому регулируют сигнал управления статического источника до уравнивания частот и фаз выходных напряжений источников, выравнивают величины напряжений источников, и подключают статический источник в режим параллельной работы, отличающийся тем, что формируют сигнал задания для тока статического источника, измеряют мгновенное значение тока статического источника, формируют разностный сигнал путем вычитания сигнала, пропорционального мгновенному значению тока статического источника, из сигнала задания для его тока, и суммируют полученный разностный сигнал с сигналом управления, устанавливают сигнал задания тока статического источника до подключения равным нулю, и, после подключения статического источника в режим параллельной работы на общую нагрузку, плавно увеличивают сигнал задания для тока статического источника до значения, соответствующего номинальному току статического источника.The method of synchronization and connection in parallel operation of an adjustable static source of alternating voltage and an alternating voltage source, which consists in measuring the instantaneous values of the output voltages of the sources, generating a signal proportional to the phase difference of the output voltages of the sources, by which the control signal of the static source is adjusted before frequency equalization and phases of the output voltage of the sources, equalize the voltage values of the sources, and connect a static source in m of parallel operation, characterized in that they generate a reference signal for the static source current, measure the instantaneous value of the static source current, generate a difference signal by subtracting the signal proportional to the instantaneous value of the static source current from the reference signal for its current, and summarize the received differential signal with the control signal, set the signal for setting the current of the static source before connecting equal to zero, and, after connecting the static source to the parallel operation mode, and the total load, smoothly increase the reference signal for the current of the static source to a value corresponding to the rated current of the static source.
