Control method of serial type voltage fluctuation compensator

摘要

(57) Abstract Objective The voltage which at such as terminal substation is interposed in series into systemWith the die inverter, it adds compensates the voltage fluctuation of downstream sideIn case of the ru, in the voltage fluctuation which high-level side will be slowNot to respond, to respond to only instantaneous fluctuation, equipment permitting/insertingAs reduction of the tonnage is assured, not only high-level side downstream sideVoltage the control method which can be compensated is offered vis-a-vis voltage fluctuationru. Constitution Long cyclic forming of voltage of high-level side of voltage die inverterTo designate amount as voltage set point, in this downstream side of the voltage die inverterWay (the output side) voltage (DC value) it follows, command electricityWith the closed-loop control pressure is given, the voltage die in barta PWM is controlled.
