Internet of Things Based Auxiliary Control System for Smart Substation

Abstract

In order to solve the present situation that auxiliary facilities in substation separate from each other and unable to achieve intelligent interactive features, this paper presents the smart substation auxiliary control system based on the IoT (Internet of Things). The system monitors and controls the production auxiliary system of substation, and in the background using IEC61850 communication protocol to achieve the auxiliary production system internal and mutual coordination linkage and information remote transmission. The system integrates all the substation auxiliary facilities, including video monitoring subsystem, security subsystem, lighting subsystem, power supply subsystem and auxiliary system optimal control subsystem, providing smart substation of informatization, automation and interaction auxiliary support.
