It may be implemented remotely to have access to function.SOA service bus realizes that safety is recognized using " CIM/G, DL476 " standard agreement as technical foundation
Card, picture obtain and the function of Refresh Data.
Realize that the subterranean equipment IEC61850 model scd file remotely had access to completes model storage, main website with monitor on the spot
Communication linkage is established, main website initiation remotely has access to service request, obtains plant stand end through SOA service bus by remotely having access to process
Graphic file and picture real time data, the picture data of real time inspection monitoring host computer on the spot.It realizes total in completion power station
While quickly control according to storage and core data, simplifying, being unimpeded and stable for the entire secondary network of energy-accumulating power station, solution ensure that
The storage for energy-accumulating power station data of having determined and the core contradiction of real-time control.
IMMS due to based on the auspicious NS5000 intelligent substation monitoring technology platform in south, not only support energy-accumulating power station monitoring with just
Remotely having access between ground monitoring is also remotely adjusted between support remote dispatching main website and energy-accumulating power station monitoring by reasonable disposition
It reads.In the access of more energy-accumulating power station clusters, the present invention can also serve as remote scheduling role.
It is huge in view of the data volume of energy-accumulating power station, while there is the demand quickly controlled again, totally according to storage and core
Data quickly control that there are contradictions.The case where occupying valuable real-time data network in order to avoid a large amount of operation/maintenance data occurs,
For different application scenarios, the present invention develops one in prior art basis using unified IEC61850 communications protocol
Kind is based on big data bedding storage, energy management centralized control, the long-range energy-accumulating power station comprehensive management and control system for having access to technology
System, the system realize power station totally according to storage, quickly concentration stability contorting and remote real-time monitoring, ensure that energy-accumulating power station is whole
Simplifying, being unimpeded and stable for a secondary network, solves the storage of energy-accumulating power station data and the core contradiction of real-time control.
