The invention discloses a security power supply visualization system and method, and relates to the field of power grid power supply protection. The security power supply visualization system and method takes one-graph and dual-visualization as the framework, realizes displaying of one power graph and one resource distribution graph of a slave station-line-transformer-subscriber, comprehensively masters the operation condition, the risk, the plan and the on-site video of power supply equipment, displays the distribution condition of security power supply resources, the activity progress condition of a security power supply place and the track information of patrol personnel in a geographic visualization manner, and displays the security power supply equipment preparation work progress, themeeting place activity progress and the real-time weather information in a graphical manner. The security power supply visualization system is integrated with a main network automation system, a distribution network automation system, a metering automation system, a power grid safety production management subsystem, a Guangxi power grid company short message platform, a transformer substation unified video monitoring platform, a power grid GIS platform and other service systems, can realize transverse data communication, can guarantee that abnormal movement of the power protection equipment is discovered in advance and processed preferentially, can achieve multi-department linkage, can carry out work in parallel, and can provide important decision analysis for command work of power protection and supply.
