Construct Power Main Grid into a Railgrid

This paper briefly analyzes the problems existing in the current power system, and puts forward the fundamental measures to solve the problems: from five aspects, to reconstruct and rebuild Power Main Grid into a RAILGRID. Meanwhile, puts forward that the power system should go back to the most basic functions, and transform the most basic transmission mode of electricity and electric energy. The goal is fundamentally to solve the problems of security and stability of ultra-large capacity power grid and energy interconnection power grid.
