SERIES COMPENSATION CONTROL METHOD FOR ELECTRIC POWER SYSTEM AND SERIES COMPENSATION DEVICE USING IT

摘要

PURPOSE:To stabilize a system by minimizing the lowering of stability of the system during a system trouble and at the same time to prevent an antiphase current from flowing through the system during a reconnection cycle for preventing a trouble to reduce a stress to a generator. CONSTITUTION:An electric power system reactance 5 which is changed when a trouble generated in a system is removed and then reconnection is made, is compensation for by using a series compensation device 6 constituted of a series capacitor and a control device for controlling a compensation degree and also the compensation degree is controlled so that the reactance of the system is balanced.
