Over ten years have passed since the start of operation of on-line TSC (Transient Stability Control) system, which is the worlds first online-type stabilization system for electric power systems. This paper discusses the challenges this on-line TSC system has so far faced in its actual operations and our development of new technologies and functions to overcome these challenges. Using transient stability ranking technique based on simplified transient stability calculation, new TSC system expect two advantages; (1) Accurate response to changes in power system conditions. (2) Using differentiation of severity of stability for each contingency contribute cost reduction.
