Abstract: Aiming at the electrical power supply monitoring and command system for major event, based on the analysis of system requirement and characteristics, the paper put forward the architecture of application integration, conventional and special functions, physical and logical design, etc., worked out the key technical issues including real time data pushing, equipment model synchronization, multisystem application integration, and the schemes and contents for the monitoring, early alarming, alarming for the involved transmission, transformation, distribution, and guaranteed power supply area were highlighted. A corresponding system was successfully developed and played a key role in 2rd Wuzhen internet international conference. The application results indicate that, the command efficiency is greatly improved, can provide the real time monitoring data and alarming to the commanders and supervisors.

Key words: major event; electrical power supply monitoring and command system; system construction; key technologies; key applications
