The on-line TSC (Transient Stability Control) system is the worlds first online-type stabilization system for electric power systems, which realizes optimum stabilized control of moment-by-moment power system conditions by obtaining power system information online and carrying out stability calculations at certain intervals.This paper discusses the new transient stability ranking method for severity of each contingency, which will be introduced to the new on-line TSC system of Chubu Electric Power Company. The ranking method is based on system parameter estimation and the Extended Equal Area Criterion. The method can be applied to unbalanced fault.
