Abstract
The invention discloses a county region distribution network operation fault analysis and diagnosis platform. The platform comprises an operation monitoring and warming module, a fault diagnosis auxiliary module, an EMS model splicing and mapping module and an electrical island map extracted GPMS full net diagram module. The county region distribution network operation fault analysis and diagnosis platform provides timely fault warming and fault judgment auxiliary means, can basically judge a fault position, meanwhile can preliminarily the failure property, provides timely information for distribution network dispatching and rush-repairing commanding staff, accomplishes fault diagnosis and positioning within the shortest time, reduces the distribution network fault power service interruption time, and enhances the service level of electric power companies.
Description
Technical field
The present invention relates to a kind of fault analysis and diagnosis platform, particularly a kind of county territory distribution operational failure analysis diagnostic platform.
Background technology
At present, counties in China distribution automation degree is general not high, generally only accomplish to be monitored various kinds of equipment in transformer station by SCADA system, still lack effective instrument and carry out real-time monitoring to the ruuning situation of power distribution network, this makes power distribution network operations staff cannot grasp operational factor and the running status of distribution network line in real time accurately.Show in actual motion management, after distribution line breaks down, operations staff often takes to receive a crime report, the mode of line walking etc. " original " the most carries out malfunction elimination to distribution line, and this have impact on operating efficiency greatly, is also unfavorable for the raising of customer power supply reliability index simultaneously.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, and provide a kind of under distribution automation itself measures not enough situation, territory, the county distribution operational failure analysis diagnostic platform of line fault Real-time Alarm can be realized.
A kind of county's territory distribution operational failure analysis diagnostic platform, includes operation monitoring and alarm module, failure diagnosis supplementary module, EMS model splicing and mapping block, electrical island figure extracts GPMS the whole network module and form,
Described model splicing and mapping block import the 10kV outgoing compartment model of the transformer station of EMS system by EMS system CIS interface, this model is CIM model, carry out splicing and mapping with the 10kV outgoing compartment model of the intrasystem transformer station of DMS, a model of realization and EMS system is connected;
Described operation monitoring and alarm module obtain from EMS system that 10kV part feeder line is meritorious, electric current, fault alarm signal, real time monitoring is also according to current break decision rule, the mean value contrast of the current value being specially Real-Time Monitoring outlet switch switching current therewith, if current break exceedes setting mutation current percentage, then think current break, produce Real-time Alarm, and show with multilayer light word and real-time issues mode;
Described failure diagnosis supplementary module is according to warning information, in conjunction with real time data calling and the confirmation that has a power failure of suspicious distribution transforming list, substantially can failure judgement place, simultaneously can the character of preliminary failure judgement, for distribution scheduling and repairing commanding provide information timely, make up the deficiency of power dispatching data acquisition system real-time data acquisition coverage rate;
Described electrical island figure abstraction module is from the whole network figure basis that GPMS imports, analyzed by model topology, the looped network figure of auto Segmentation electrical interconnection out, comprise trunk and branch line, or be called electrical island winding diagram, electrical island winding diagram provides mutual graphic panning well, search location, topological analysis function, flutter analytic function and supply path analysis is provided, supply district is analyzed, turn power supply analysis, main function supports to carry out topological analysis calculating to selected equipment, distribution transforming list in automatic formation supply district, this list comprises responsible consumer, by distribution transforming list in anticipation fault coverage, in conjunction with the suspicious distribution transforming real time data calling of marketing power information acquisition system, and the confirmation that has a power failure, can determine fault zone fast.
This software imports the 10kV outgoing compartment model (CIM model) of the transformer station of EMS system by EMS system CIS interface, carry out splicing and mapping with the 10kV outgoing compartment model of the intrasystem transformer station of DMS, a model of realization and EMS system is connected.
In sum, the present invention's following advantage compared to existing technology:
County of the present invention territory distribution operational failure analysis diagnostic platform provides timely fault warning and breakdown judge supplementary means, substantially can the place of failure judgement, simultaneously can the character of preliminary failure judgement, for distribution scheduling and repairing commanding provide information timely, failure diagnosis location is completed in the shortest time, reduce Distribution Network Failure interruption duration, promote Utilities Electric Co.'s service level.The present invention also provides electrical island winding diagram to provide the function such as mutual graphic panning well, search location, topological analysis, the man-machine interaction experience of providing convenience.In conjunction with suspicious distribution transforming real time data calling and the confirmation that has a power failure of marketing power information acquisition system, can determine fault zone fast.
Accompanying drawing explanation
Fig. 1 is county of the present invention territory distribution operational failure analysis diagnostic platform Organization Chart.
Fig. 2 is that the fault of county of the present invention territory distribution operational failure analysis diagnostic platform studies and judges logical flow chart.
Embodiment
Below in conjunction with embodiment, the present invention is described in more detail.
Embodiment 1
A kind of county's territory distribution operational failure analysis diagnostic platform, includes operation monitoring and alarm module, failure diagnosis supplementary module, EMS model splicing and mapping block, electrical island figure extracts GPMS the whole network module and form,
Described model splicing and mapping block import the 10kV outgoing compartment model of the transformer station of EMS system by EMS system CIS interface, this model is CIM model, carry out splicing and mapping with the 10kV outgoing compartment model of the intrasystem transformer station of DMS, a model of realization and EMS system is connected;
Described operation monitoring and alarm module obtain from EMS system that 10kV part feeder line is meritorious, electric current, fault alarm signal, real time monitoring is also according to current break decision rule, the mean value contrast of the current value being specially Real-Time Monitoring outlet switch switching current therewith, if current break exceedes setting mutation current percentage, then think current break, produce Real-time Alarm, and show with multilayer light word and real-time issues mode;
Described failure diagnosis supplementary module is according to warning information, in conjunction with real time data calling and the confirmation that has a power failure of suspicious distribution transforming list, substantially can failure judgement place, simultaneously can the character of preliminary failure judgement, for distribution scheduling and repairing commanding provide information timely, make up the deficiency of power dispatching data acquisition system real-time data acquisition coverage rate;
