The application software framework about distributed intelligent alarm information in intelligent substation

Abstract

With rapid development of the power grid construction and the new energy, power grid operating characteristic has major changes. The intelligent alarm processing function in the existing dispatching automation system cannot meet the requirements of the power grid operation. Distributed application has become a new application requirement for power grid dispatching automation system. In recent years, the distributed application research on distributed state estimation, distributed intelligent alarm, and distributed SCADA has been reported. Base on the status and application of the intelligent power network dispatch and control system, the intelligent alarm function analyzes the difference between the traditional alarm system and the distributed intelligent alarm system. And the paper studies the architecture and specification of the two-level distributed intelligent alarm system and analyzes the value and its future application prospect of distributed intelligent alarm for dispatching operation.
