Detailed description of the invention
Fig. 1 is the modeling of relay protection information data, Stored Procedure schematic diagram in the present invention；
Fig. 2 is that relay protection information data shares schematic diagram in the present invention.
Specific embodiment
Below with reference to attached drawing, technical solution of the present invention and beneficial effect are described in detail.
The present invention provides a kind of towards the relay protection information sharing method more applied, and includes the following steps:
Step 1, the information data of protective relaying device in substation is modeled and is stored, as shown in Figure 1.
Firstly, predefined protective relaying device Information Data model.According to the classification of protective relaying device, according to " DL/T
The 7-3rd part of 860.73-2004 substation communication networks and system: the basic communication structure sharing of substation and feeder plant
Data class " and " the 7-4th part of 860.74-2006 substation communication network of DL/T and system: substation and feeder plant
Basic communication structure compatible logical node class and data class " model data format as defined in standard, define route protection, bus is protected
Eight classes such as shield, tranformer protection, breaker protection, highly resistance protection, stub protection, automatic safety device, mother sectionalised protection
Protective relaying device data model.
Secondly, the creation full data pattern file of substation relay protection device.According to " DL/T 860.6-2008 substation
The 6th part of communication network and system: communication configuration description language in substation related with intelligent electronic device " regulation, according to
The relay protection data model of aforementioned definitions, by all protective relaying device models of actual disposition in substation with a SCD
File (transformer substation system configuration file) description, as additional relay protection SCD information data.
Finally, storage relay protection information data.By relay protection information data whole in the substation of acquisition and aforementioned
Additional relay protection SCD information data, the relay protection data model defined according to a are stored.Data storage uses two kinds
Form: real time data and historical data.Real time data only stores current time collected protective relaying device information data.It goes through
The protective relaying device information data of protective relaying device information data or period acquisition that the storage of history data changes each time, is adopted
It is settable to collect the period.
Step 2, by relay protection information data sharing is to different application in substation, as shown in Figure 2.
Based on ethernet communication, service-oriented relay protection information communion system (SOA) is built；
Using " GB/T 33602-2017 electric system generic service agreement " as the communication protocol of data interaction.
A series of interface services and service defined according to " GB/T 33602-2017 electric system generic service agreement " are former
Language realizes a variety of applications to relay protection data while shared demand.
Data requirements apply " creation service " using " GB/T 33602-2017 electric system generic service agreement " to after
The personalized customization service of electric protection information sharing application registration, it is shared to realize that relay protection information customizes.Data requirements side
According to own system to the logic of data requirements, multiple base interface services are combined according to sequencing, using " creation
The service primitive of service " records these interface services, forms " customizing service ".Data requirements is applied to be connect by " creation service "
Mouth sends creation " customizing service " to relay protection information sharing application and requests, and relay protection information sharing application replys confirmation
Afterwards, that is, indicating, which " should customize service ", succeeds in registration.In subsequent shared data interactive process, data requirements is applied without more
Secondary calling basic interface service, but call directly " the customizing service " interface and data sharing can be completed.
Data requirements application can also nullify registered " customize and service " using " delete and service ".
In summary, the present invention is a kind of towards the relay protection information sharing method more applied, can make it is different types of after
Electric protection information data unitizes, interface service standardization, and Services Composition diversification reaches data-optimized configuration, access conveniently
Quick and share purpose builds investment reduction cost for substation, reduces installation and maintenance.
The above examples only illustrate the technical idea of the present invention, and this does not limit the scope of protection of the present invention, all
According to the technical idea provided by the invention, any changes made on the basis of the technical scheme each falls within the scope of the present invention
Within.
