The present invention discloses a dispatching operation information patrol inspection method and system, and belongs to the electric power dispatching automation technology field. The method comprises the steps of obtaining the power grid real-time operation data from an OPEN3000 dispatching automation monitoring system; according to the obtained power grid real-time operation data, establishing a transformer substation model of the connection modes of all power plants in a power grid and the equipment in a transformer substation and the equipment connection sequences; pre-processing the obtained power grid real-time operation data to obtain the effective measurement data; according to the effective measurement data and the switch on-off data in the transformer substation, implementing an alarm evaluation strategy; utilizing the alarm evaluation strategy to evaluate the alarm information, and then classifying the alarm information according to different alarm types to display in an alarm page. According to the present invention, by pre-processing the acquired measurement data, a lot of frequent invalid alarm information is shielded, the number of the alarm information that the monitoring personnel need to check is reduced substantially, so that the monitoring personnel can determine and process accurately, rapidly and appropriately.
