Abstract
The co- ordination of the electric power systems in Japan is one of the most important post-bellum measures worthy of serious consideration.
At the present time, almost all industries bad been electrified but there remains to be seen, in the near future, the electrification of main railways and electrical ship propulsion.
During the war, the interconnection of electric power systems was much discussed and adequate measures had been adapted in various countries in the world.
In Japan the necessity of interconnection of transmission lines was discussed many years ago_??_and the electrical enterprises law was amended in 1916, adding an article which gives the right fo the Government to force any two or more corporations to tie their lines when the Government finds it necessary for the public benefit. Although the original intention of this amendment was to minimize the case of shut-down of transmission lines, it stimulated the interconnection from economical point of view such as for utilizing surplus water and saving coal. Consequently, since that time, many of the power systems are voluntarily interconnected, this course having often being suggested by the Government, Rece_??_tly after the war, various power corporations are f_??_equently amulgamated and complete co-ordination will be carried out.
To bring about the cordination of electric power systems many difficulties must be surmounted. Wi hout clear analysis and definite understanding of the subject, the task of unifiying the systems will rosu't in a dismal failure, Thus, the co-ordination of power systems should he carried out where the following advantages can be r_??_ally obtained and if it has been actually already done, the benefit therefrom should be distributed tq the public.
