This article presents a new sequence-checking method for a large power plant which has a shunt-wound reactor on the connecting line. By simulating the new method on computer, the change of current and voltage is checked and the equipment protection scheme is elicited. Finally the problem of excitation system is resolved by integrate means , and the phase checking experiment is completed successfully.
