Embodiment
Below in conjunction with embodiment, the invention will be further described.
Embodiment one: a kind of dynamic measurement information sharing method based on electric network model obtaining the information of major network system for realizing distribution network systems, for: electric network model and real time data are packaged into message packet and send by major network system, distribution network systems extracts electric network model and real-time reception real time data, to realize dynamic measurement information sharing.Major network system and distribution network systems are based on same D5000(intelligent grid Dispatching Control System) platform, platform provides the cross-system transmission service of message
Concrete, share method and realized by following steps:
(1) major network system derives the file containing grid model data, and distribution network systems extracts grid model data from containing the file of grid model data, and sets up electric network model in distribution network systems.Namely with IEC61970 standard for foundation, major network EMS system derives the XML file containing grid model data, as shown in Figure 2, electrical power distribution automatization system (distribution network systems) extracts grid model data from XML model file, creates major network electric network model in distribution main station system.
(2) real time data collected is converted into real-time messages message and is sent in real time by information gateway by major network system.The i.e. substation information that will collect of major network system, is sent in real time by information gateway: real-time messages message is sent to messaging bus by major network system FES application, and information gateway obtains real-time messages message by messaging bus, and is transmitted to distribution network systems.
(3) distribution network systems is translated into system internal message by information gateway real-time reception real-time messages message, and the content of conversion mainly comprises the device id in type of message and message.
(4) distribution network systems resolution system inside story and obtain the information of major network system, process major network real time information in real time, analysis mode is identical with processing distribution real time data message.
In such scheme, the standard of electric network model is CIMXML/RDF, namely adopts CIM (common information model).CIMXML/RDF is that each device object distributes unique RDF; RDF_ID in model file generates according to the KEY_ID of major network devices in system.
The foundation that electrical power distribution automatization system creates electric network model identifies concrete grid equipment type according to the RDF_ID of major network model file, and according to original model creation standard, such as table number, recording mechanism etc. generate major network electric network model.
The substation information that major network system will collect, is sent in real time by information gateway; Information gateway is D5000(intelligent grid Dispatching Control System) software interface program of platform, realize the forwarding capability of message; Information gateway is registered to the real time data message channel of system, according to the type of message in configuration file, determines the information that will forward.
The information gateway of electrical power distribution automatization system is the message sink program of distribution network systems, realizes the real-time reception of major network message, and be sent to that internal system sets up for receive major network system send out the specific messages receive path of message.The message transformation process of distribution network systems deployment-specific, extract the valid data in major network message, specific messages receive path is incorporated in the original messaging bus of distribution network systems.
Be converted into the message of internal system after electrical power distribution automatization system (D5200) receives major network message, the content of conversion mainly comprises the model in type of message and message.Major network system and distribution network systems have respective type of message definition standard, need by the type of message changing into distribution network systems definition corresponding to the remote signalling in major network system, telemetry message type; Real time data form in major network message is according to the model description of major network, and distribution network systems cannot Direct Recognition major network model, and before carrying out Data Analysis, major network system model is changed into inner model of system according to RDF_ID by distribution message preliminary treatment process.
In the present invention, electrical power distribution automatization system directly obtains the message data of major network inside, without the need to forwarding through major network secondary system, reduce the intermediate link of real-time Data Transmission, improve data transmission efficiency, for the closed-loop of feeder automation runs, provide data promptly and accurately to ensure.
Above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
