The Analysis of Single Bus-Bar Connection and its Switching Operation

Abstract

Main electrical wiring is a circuit diagram which is used to meet the production needs of the power transmission and distribution and in accordance with a certain manner and order and use provisions of graphic symbols and text code to connect once equipment (generator transformer switching equipment,etc.) together. It reflects the basic structure and function of traction substations and substation (power generation). In operation, it shows the primary operating mode of substation (power generation) and high voltage grid connection and associated feeder devices and become the basis of controlling and scheduling apparatus. This paper analyzes single-bus connection from the reliability, flexibility and economy point of view, then outlined the typical single-bus wiring switching operation principles and methods.
