Abstract
PURPOSE: To increase the safety when high speed control is requested, by converting the analog control signal into digital signal to keep it for a given time, predicting the change in the control signal for this hold time, and performing the corrective operation with the predicted signal.
CONSTITUTION: The controlled analog signal of the synchronous generator G having the field winding F controlled with thyristor TH-Ex is fed to the transformer PT, the output of the transformer PT is arranged with the A/D converter X, control operation section Y, and DA converter Z, to predict the change into the control signal in sample hole time and it is fed to the digital automatic voltage adjuster D-AVR having the function performing corrective operation of the control signal with the predicted signal. Further, this output of the auxiliary transformer AU- Tr is fed to D-AVR via the DC power supply, the output of D-AVR is fed to the pulse generator P, to produce the output performing pulse phase control based on the input signal and to control SCRTH-EX, allowing to obtain stable control when the sample period and the response time are close.
