Abstract :
A method has been developed to simulate an automatic frequency control system in ac-dc power transmission on an analog computer. As an example of an ac-dc system a model of Sakuma frequency changer, between Tokyo Electric Power Co. system (50 Hz) and Chubu Electric Power Co. system (60 Hz), is studied in detail. Three new methods of automatic frequency ratio control (AFRC) by dc transmission are considered and compared. The variation of frequencies in the ac systems and the dc power change due to a step load increase in the Chubu power system are examined. These frequency variations and power change are used to optimize the parameters of the AFRC devices.
