Safety net design and implementation in Taiwan power system

摘要

The blackout event of July 29, 1999 in Taiwan power system has led to a thorough review of the current Taiwan power service reliability. An in- depth discussion of the incident causes through the analyses of load flow, transient stability (time domain), dynamic stability (frequency domain) and voltage stability is given in this paper. In order to avoid the wide spread incident to occur again, Taiwan Power Company (TPC) has designed and implemented a safety net for preventing extreme contingencies and unplanned events. This paper gives an overview of the safety net, including the design philosophy, action logic and communication structure.
