With the construction of ultra-high voltage (UHV) power grid and the rapid development of new energy

significant changes have taken place in the operation characteristics of power grid. The alarm processing function of existing dispatching automation systems

however

has not been able to adapt to the development requirements of the integrated operation for the large-scale power grid

making it necessary to effect integrated processing of the alarm information on each operation of real-time monitoring and control in the dispatch center

while improving dispatcher ability of the overall awareness of power grid states and emergency handling of equipment faults. According to the research and application of integrated smart alarm function based on smart grid dispatching and control systems

the overall framework and key techniques of the integrated smart alarm are treated

to form the integrated alarm oriented to dispatch operation mode

online fast diagnosis of equipment faults and real-time sharing of fault information between multi-level dispatch centers. The application effect and future research prospects are given.
