A METHOD FOR SEISMIC RELIABILITY ANALYSIS OF SECONDARY TRANSMISSION SYSTEM

Abstract

This paper presents a probabilistic method for estimating the minimum power loss of secondary transmission systems in a seismic event. First, the power loss was defined. Second, a state-of-the-art study for a system switching method was described and an algorithm was proposed on the basis of Genetic Algorithm (GA) and Monte Carlo simulation. Third, it was indicated that the developed method was an effective means of seismic-reliability analysis for secondary transmission systems. Finally, this method was applied to a seismic reliability analysis of a real secondary transmission system in Kushiro, Hokkaido, Japan.
