【Abstract】 The inner communication of automation of electric system in substations decides whether the substation could operation successfully.This paper analyses how the electromagnetism and the practicability of the system assort the inner communication,and expatiates how substations of different voltage level choose different communicating net from the economic aspect and index point aspect,and analyses the applying status of the 103 protocl specifically,and then points out how the different understandings of different companies results in different problems,and shows some advice resolving the problems.更多还原
