Abstract

Abstract: The static security analysis is one of the core functions of real-time monitoring and early warning application in the smart grid dispatching control system. The correction information by single component disconnection is restricted to sensitivity which is too simple to cover actual needs. Based on an in-depth analysis of grid division's characteristics, an online identification technology is raised based upon tree search method, and an improvement is made on the static security on-line correction strategy, which can provide a real time decision-making information of division connection device's loop closure aiming at over-limit correction of devices. The technology is realized and put into operation in dispatching control system of North China power grid. Practical verification shows that the analysis and calculation results are accurate and reliable, and the technology can improve the intelligent and automatic level of online-analysis applications.

Key words: grid division, auto-identification, division connection device, static security on-line correction
