The invention discloses a local-level dispatch
supporting system capable of improving an analyzing and
processing capability of a dispatcher during accident generation and belongs to the field of control. The local-level dispatch
supporting system is characterized by setting automatic switching device of
standby power supply model in an online safety analysis module in a local-level dispatching
system; in the scanning of preconceived faults of the online static safety analysis module, achieving N-1 scanning after the operation of the automatic switching device of the
standby power supply, computing the
power flow after the operation of the automatic switching device of
standby power supply in order to accurately reflect a
power flow change after the operation of the automatic switching device of the standby power supply, and generating an accident preconceived text based on an analyzed result. When the online static safety analysis module performs N-1 scanning, a dispatcher may autonomously set the operating mode of the automatic switching device of standby power supply so as to simulate and analyze
power grid power flow distribution states in different operating
modes, enable the dispatcher to be capable of online researching the safety stability of an
regional power grid in real time, improve the safety stability of real-time online
power grid research, generate available accident preconceived texts for the dispatcher, and improve a capability of treating emergency
power grid accidents for the dispatcher.
