Method laying of submarine power transmission lines, power grid, and transmission path generation device

摘要

The present invention while maintaining high reliability, part of the power grid is possible to build a stable power transmission possible transmission network even if disconnected, to provide a laying method of submarine power transmission line. The present invention provides a laying method for laying the submarine transmission line, separated by a sea area 310, a transmission line so as to surround the 4.5km ² or more of the land section 210 is a coastal area laying waters transmission path that heat loss or resistance value compared with the existing transmission path 110 is reduced along with the closing the open circular of the existing transmission route 110, laying submarine power transmission line, existing transmission path 110 to laying the submarine transmission line to connect to, to build a closed ring-shaped transmission path.FIELD 1
