Abstract

Estimating electric power supply restrictions after the Nankai Trough earthquake and evaluating the need for reinforcing the capacity of lines interconnecting power supply areas, we found that capacity reinforcement of the Chubu-Kansai interconnection line used an electricity supply capability in the 60 Hz area of the western part of Japan after the disaster. We also found that this is effective in reducing risk in electric power supply restrictions, based on certain conditions. We also found by estimating construction and maintenance costs that the capacity reinforcement of the Chubu-Kansai interconnection line reduces risk and costs less than an east-west interconnection line.
