The correct choose of the voltage level and the rational scheming of the voltage level of sequence can satisfy the needs of the economic development better.With the rapid development of our country makes the demand of electricity growth fast,leading to the current voltage and the voltage sequence has diaplayed inadaptability.As a result, we should seize the opportunity that electricity load are increasing rapidly and grid extending massively,and allocate voltage rank rationally considering kinds of factors including the use of new technology and ideas.This article analysed the present situation about voltage level scheming in China as well as in developed country.By means of technical-economy comparison of the 3 distribution voltage and the comparison of rational scheming of voltage levels based on the load density,obtained the conclusion of simplifying voltage levels and boosting mediumvotlage level,put forward the rationalization proposal and basis for the rational scheming of the voltage level.
