Dispatching operation information patrol inspection method and system

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of power dispatching automation, in particular to a method and system for inspecting dispatching operation information. Background technique [0002] With the continuous advancement of the large-scale operation system of the power system and the acceleration of the construction of smart substations, the amount of monitoring information access has increased rapidly, and monitoring personnel need to extract important fault information from a large number of signals. [0003] At present, the OPEN3000 dispatching automatic monitoring system is generally used in the power system to display the alarm information, so that the monitoring personnel can extract important information. However, the OPEN3000 scheduling automation monitoring system displays these alarm information in a chronological order. Even if the alarm information is not classified through the message layering mechanism, different alarm pages will st...

AI Technical Summary

Problems solved by technology

[0004] First, there are a large number of invalid signals in the huge amount of alarm information, which seriously interferes with the monitoring personnel's extraction of important information

Moreover, the alarm page of the OPEN3000 scheduling automation monitoring system has the problem of rough message classification. The cross-line information of various measured values ​​is divided into "limit information" and displayed. Under the huge amount of information, it is difficult to ensure that the Pay attention to the key measurement accident information at the first time

Therefore, it is difficult for monitoring personnel to confirm various alarm information through the OPEN3000 dispatching automation monitoring system

[0005] The second is that the OPEN3000 dispatching automation monitoring system lacks alarm means for the data uploaded by power plants and substations that do not change for a long time, and can only rely on monitoring personnel to conduct manual verification, which is a waste of manpower

[0006] Third, the OPEN3000 dispatch automation monitoring system lacks alarms for important information such as multi-line load overload, compressor overload, bus voltage fluctuation, and single-phase grounding of the bus.

Monitoring personnel can only confirm by manually querying historical data and on-site telephone reports, which seriously affects the real-time performance of monitoring personnel and dispatchers for corresponding scheduling processing

[0007] Fourth, the alarm text information of the OPEN3000 dispatch automation monitoring system uses a scrolling prompt method, which is equivalent to historical information browsing, which can only reflect the occurrence of accidents or abnormal information, and cannot reflect whether the current cause of the alarm still exists

Moreover, when the monitoring personnel change over, the successor cannot check all the alarm signals that are still in the alarm state

[0008] Fifth, the OPEN3000 scheduling automation monitoring system cannot configure alarms for the same type of equipment for measurement values ​​other than conventional equipment. It can only configure alarm limits or alarm information for each unconventional measurement value, and cannot target the same type of equipment. For unconventional devices of different types, a unified alarm strategy configuration is performed

[0009] Sixth, the OPEN3000 scheduling automation monitoring system lacks a reasonable data validity judgment strategy, only "no change", "jump", "invalid", "suspicious", "blocked", "normal", "set number" , "take state estimation", "calculated value", and "suspicious" state judgments that describe the validity of the value itself cannot be used to judge and deduce the validity of the overall value based on the actual state of the station
