Auxiliary control system of intelligent transformer substation

The utility model relates to the electricity field, in particular to an auxiliary control system of an intelligent transformer substation. The auxiliary control system comprises an intelligent auxiliary controller, a passive optical network and an intelligent transformer substation subsystem group, wherein the intelligent auxiliary controller and the passive optical network are connected with a passive optical switch. The intelligent transformer substation subsystem group is connected to the passive optical network in an integration mode through a network interface and/or an all-optical intelligent interface and comprises one or more of a video monitoring and visualizing operation monitor system, an intelligent patrol system, an environment monitoring system, a light control system, a perimeter warning system, a fire-fighting warning system and an entrance guard system. The intelligent auxiliary controller is used for processing received electrical signals. The video monitoring and visualizing operation monitor system is used for acquiring images and transmitting the images to the intelligent auxiliary controller. The auxiliary control system can perform integral management to the intelligent transformer substation subsystem group.
