A method of dispatching remote security remote checking based on service

Abstract

The invention discloses a dispatching remote safety remote control checking method based on service. A system architecture facing the service is supported, a request / response mode provided by a service bus is adopted, a substation remote control check service is called by virtue of an interface provided by the service bus when a dispatching main station performs the remote control, the remote control check information is triply remotely checked to obtain a check result so as to realize a remote control check function, and the safety and reliability of the remote control operation can be improved. The triple remote control information check refers to the security certification of the service bus, and the information check and the remote control check of a measure and control device are carried out by virtue of the remote control check service; the dispatching main station does not need to directly call an application of a substation, so that the specific implementation details of the service provided by the substation does not need to be understood, and the flexibility is high; when the demand of the main station is changed, only the service provided by the substation needs to be modified, the interface providing the service does not need to be modified, and the expandability is relatively high.

Description

technical field [0001] The invention relates to a service-based dispatching remote security remote checking method, which belongs to the field of power system automation. Background technique [0002] At present, the use of remote control technology in power grids has become very common, and most substations have realized unattended operation. The monitoring work of the substation is centralized from the decentralized station-side monitoring to the monitoring center. The monitoring personnel implement remote monitoring and control of the substation through the dispatching automation master station system and the substation-side telecontrol system. [0003] At present, the telecontrol protocol of the master station system and the station system mainly adopts IEC101 and IEC104. The remote control commands transmitted by them only include the remote control point number and the remote control value. If it is judged that the point number exists, the remote control will be carri...

Problems solved by technology

[0003] At present, the telecontrol protocol of the master station system and the station system mainly adopts IEC101 and IEC104. The remote control commands transmitted by them only include the remote control point number and the remote control value. If it is judged that the point number exists, the remote control will be carried out. Once there is an error in the association of the remote control point of the master station system or the remote control point of the station end system does not correspond to the master station end system, false remote control may occur. Both automation personnel and dispatching and monitoring personnel have brought great pressure, and will also pose a threat to the safe operation of the power grid

[0004] In addition, in order to improve the safety of remote remote control verification, it is only realized by expanding the remote control protocol at present. In this way, both the master station and the sub-station must be modified. The process is cumbersome, the flexibility is not high, and the scalability is poor.
