Control device of the DC can power voltage compensation device

摘要

(57) Abstract Objective Output current of direct current feeding voltage compensator suddenly increaseAdding the feeding which is based on retarded in closed-loop control system when it doesDecrease of voltage is prevented. Constitution Entry electricity of direct current feeding voltage control device (DCVR)Entry electric current (= output current) from of flow detector CT integrating circuitIntegral with 11, entry electric current to add with the adder, entry electric currentWhen augmenting suddenly, the choppings that try output. ThisOutput the diode D_{3 which} cuts the output of negative number and output electricityThrough pressure regulator VR_2, amendment output of the amendment circuit 10, electricityPressure amplifier 7, phase control circuit 8, gate signal generation circuit 9And others in the phase control circuit 8 of the control circuit of DCVR which becomes voltage unTo input separately from pu output, retarded of control type of voltage amplifier typeTo cover, decrease of the feeding voltage with the sudden augmentation of output currentIt prevents.
