1, the foundation of panorama data kernel model: with reference to accompanying drawing 1, comprise electric system logical model and electric power physical equipment and measurement thereof, core information model has been contained the information that needs integration in the systems such as energy management system, transmission of electricity on-line monitoring, power transformation on-line monitoring system, intelligent patrol detection infosystem.
Wherein electric system logical model integral body is described as electric system resource (PowerSystemResource) system, according to the feature of resource, is divided into equipment container (EquipmentContainer) and two Main Branches of equipment (Equipment).The subclass of equipment comprises various conductive equipments (ConductingEquipment), utility appliance (AuxiliaryEquipment).Conductive equipment is connected to tie point (ConnectivityNode) by terminal (Terminal), and the topology that forms logic electrical network connects.
Electric power for physical equipment assets (Asset) system represent, with respect to electric system resource, pay close attention to the function of grid equipment, physical equipment pay close attention to equipment production firm, model, batch, the characteristic of the assets aspect such as the time of making the product, the time of putting into operation, be content indispensable in grid equipment lifecycle management.Each subclass of Asset forms the mapping relations with major equipment subclass on the whole.
Measurement system forms by measuring (Measurement) and measuring value (MeasurementValue) and subclass thereof.The measuring value throughput measured value source (MeasurementValueSource) that is derived from different system is distinguished, and is convenient to realize multi-data source management.
2, the expansion of information model: for the IEC TC57 CIM content in the integrated information platform of modeling not yet, expand and merge the information model that each professional system needs according to the mode strengthening step by step that increases attribute implication, newly-increased attribute, newly-increased associated, newly-increased class.With the example of two extended models, set forth below.
Example 1, with reference to accompanying drawing 2, for the video data of management from transformer substation video (fire-fighting security protection) backup system, set up and inherit from the video channel class (VideoChannel) of Equipment class and inherit from the video substation of EquipmentContainer class class (VideoStation) and video main frame class (VideoHost) accordingly.
Example 2, with reference to accompanying drawing 3, for management is from the communication facilities data in distribution communication monitoring system, set up the communication device class (DNetEquipment) of inheriting from Equipment class, and build corresponding subclass for every kind of communication device types: optical fiber cable termination equipment class (DNetOpticalLineTerminal), optical node class (DNetOpticalNetworkUnit) and optical splitter class (DNetOpticalSplitter).
3, the foundation of event information model: with reference to accompanying drawing 4, event information model is set up with reference to IEC 61970 general purpose events and subscribing interface (CIS GES) Service events model.Event source system (GESSourceSystem) is described source---the description of monitoring system of generation event; The type that needs event to be processed in each origin system is described in event classification (GESCategory); Event property (GESProperty) is every kind of event type provides a kind of universal description of name-value pair except the special nature outside the public character of all events (as time of origin, event source, severity level, message).For example, for " isolating switch item ", just there are a plurality of special natures such as " meritorious value during the action of isolating switch accident ", " accident action frequency limit value ", " accident action frequency ", " SOE mark ", " proof mark ".
The event main classes that event classification is recommended with CIS GES interface not (MainCategory) is divided into simple event, Action Events, parameter event.All categories event is paid close attention in event alarm analysis, lays particular emphasis on the analysis of parameter event.The warning of parameter when parameter (GESCondition) description state triggers for event, as the order of severity.The rule description of describing codomain for each parameter event, for example, 1. switch closes: when " circuit breaker position==close " time; 2. high alarm setting more: when " value > high alarm setting ".
In the comprehensive analysis of event alarm, the region under event source, extremely important for the spatial coherence of determining event, therefore, be that all event types increase a public nature---affiliated areas (GESArea).When the event source of an event is a power transformation station equipment, minimum that in the interval under event area sensing equipment, the three grades of equipment containers in electric pressure district and transformer station; For line facility, circuit under event area sensing equipment; For communication facilities, point to corresponding communication facilities container.
GESEventData class is used for storing selectively the event history of collecting, and the rule of browsing to support event history to recall, event being occurred is carried out the realization of the functions such as statistical study.
4, the structure of data platform: the key content that data platform builds comprises that data storage management, data collect and standardized data, services.Adopting Object-Relation Mapping mode is the main storage system of setting up, simultaneously with the pattern description all kinds of unstructured datas of Suo Guanli of serving as theme;
(1) data storage management: with reference to accompanying drawing 5, pattern information, object instance data, the historical data of extraction, data are collected the platform object that forms in process and cross reference index, the unstructured data index of operation system object is all stored in relational database, and this part data is structural datas of platform management.The various data files of collecting from operation system directly adopt document storage mode as unstructured data, by pattern and unstructured data index holistic management.Unstructured data also comprises the case data that event analysis forms.
Be not that all data all need entity migration to arrive panorama data platform, clear and definite which content migration in pattern description, which content is directly taken from operation system.The data of directly quoting, under the common guiding of pattern and cross reference index, are externally provided with normalized form by the data access interface of data platform.
(2) data are collected: under the control of pattern and data binding rule, be pooled to the demand of platform for the data of each operation system, set up and collect accordingly task.Collect task complete model, in real time, the migration of the structuring such as history, event or unstructured data, can be set as triggering and carry out (tracking data variations), regularly execution or manual intervention execution.
Model collects the mode that adopts section to be combined with increment.In collecting process, set up same object in the cross reference of the sign of platform and each system, be kept at and intersect in index of reference.Mainly, based on GDA interface, CIM/XML file, for the system that standardized access interface and file cannot be provided, write dedicated task and access its database.The object identity of model data in collecting be take electrical network tag system (Identifer System for Power Grid, the ISPG) coding rule that adopts in Production Managementsystem For Electricpower Network as main, simultaneously with reference to the Pyatyi name coding criterion of energy management system.
Electric network model data are collected work and be take EMS automated system data and collect as core and launch.Particularly to first access EMS automated system data, then be described as benchmark with (equipment container---the equipment) framework of the electrical network in EMS system (topology), import and organize the electric system resource description in other system to import.
For each monitoring system outside EMS,, according to system business actual conditions, expand corresponding information model; Determine the mapping ruler between native system business model and EMS system introducing electric network model; Finally, according to extend information model and mapping ruler, (relevant to monitoring) object data in system is extracted, changes, merges to integrated information platform.
The difficult point that electric network model data are collected is the integration (as being repeated in this description of each equipment of transformer station and subordinate thereof) of repeating data.For improving matching accuracy, with EMS electrical network (equipment container---equipment) framework (topology), be described as benchmark, make full use of the information Auto-matchings such as title, coding, in conjunction with artificial appointment verification, the description from different monitoring systems for same target is mapped to same object instance in integrated information platform the most at last.In addition, in the process of collecting at model, can utilize the redundancy of information, information authenticity is identified, improve information credibility judgement, guarantee that data can carry out subsequent treatment.
Electric network model data are collected the continuous updating that needs support model data.The mode that adopts section to be combined with increment.In collecting process, set up the cross reference index of object identity and each origin system sign in integrated information platform, support model diversity ratio, determine object increasing, delete, change, production model increment.Model data is collected 61970 standard C IS GDA interface and the CIM/XML files based on IEC, for the system that standardized access mode cannot be provided, according to its actual conditions, use its privately owned api interface or obtain its original model data by the mode of direct its background data base of access.
Real time data is collected the ability according to operation system, adopts HSDA client, E formatted file.Utilizing HSDA interface subscription data is optimal mode, and when communication consumption is little, the tracking of delta data is most effective.
The collecting of event, tracking mode comprise utilizes that GES interface is subscribed to, special use collects task from business system acquisition, according to modes such as real time data produce voluntarily.
Historical data is directly utilized operation system storage as far as possible, and except the part of data platform self precipitation, data entity will be retained in each operation system.
