The Design of Partial Electric and Control System for 500kV Substation

Abstract

The good design of the electric section in substation and its stable move may effect the electrical system of substation directly, this paper aim at the design of an electric primary section in substation and its supervisory system for the 500kv substation. based on the principle of connecting line of the electric primary section in substation and the function of the realization, and then by comparing the design of the double bus bars of double with bypass line subsection and line of 3/2 circuit breaker. we fixed the main wiring scheme. The design based on Programmable Logic Controller and supervisory control and data acquisition is an electric primary section of monitoring system.and the monitoring and control of the state and parameter in electric primary section in substation are realized by the monitoring system, which ensure the security of system, improve the level of automation and intelligent.
