Abstract: In order to solve the problems of low coordination level and low efficiency of manual text reading, this paper presents an electronic and on-line intelligent system for power network fault handling plans.First, structure and modularize the traditional contingency plan information. Then through the power system information interaction E language specification, the file transfer between different systems is realized to ensure the safety of the power system. According to the process of dealing with the actual fault of power network and the priority of dealing with various security and stability problems, the online checking and intelligent compiling system of the fault handling plan of power network is designed and developed. The analysis, identification, push and check of the plan electronization are realized, and the concrete adjustment quantity of the disposal measure in the plan is given. In the end, two calculation examples are used to verify the system’s plan check and the ability of the system to add control measures. This fully demonstrates the practicability of the system and eliminate the manual search process. The system provides the required information support for the dispatching operators of the power grid in the emergency state of the power grid failure.
