The assurance of system mode and the ability of processing system accident.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
Below by attached drawing, the present invention is described in detail.
As shown in Figure 1, the present invention provides a kind of aid decision-making systems of power distribution network, it is characterised in that；It is flat including supporting
Platform, for the support platform for monitoring in real time, being monitored online and network analysis, the support platform analyzes power distribution network in running
In the case where to accident treatment decision, to being operated after handling out decision scheme.
Operating analysis mainly include power supply risk analysis, scheduling Intelligent switching order, closed loop operation risk analysis, draw ration the power supply it is auxiliary
Help decision.
Management and running personnel can carry out traffic control decision based on power supply risk analysis, realize safety and economic coordination.
Operation ticket system use with the consistent model of real-time monitoring system, figure and real time information, avoid the repetition of data
Maintenance, mitigates the workload of maintenance personnel and the error rate of data.Aptitude Operation Order Sheet System is to operation order life cycle using complete
Row control.System, which uses, makes out an invoice in figure, executes in ticket, stringent safe related function mechanism and perfect rights management mechanism
Realize operation order intend ticket, audit, send out in advance, issue an order, execute, guarding it is man-machine combine check on, thus to greatest extent go up guarantee
The safe and stable operation of power grid.
In order to realize that the Universal and scalability of system, Aptitude Operation Order Sheet System use operation order list pattern and process
Permission is customed.System provides flexible scheduling operation flow and flexible form customizes, and what user can construct different-style is
System, realizes the flexible redundant robot framework of system.
The closed loop operation risk that the closed loop operation risk analysis will carry out system is analyzed comprehensively, it is in base
On the basis of state section, pairing ring apparatus carries out loop topology verification first, and after loop checking passes through, it successively carries out cyclization punching
Hit that the N-1 analysis after electric current, cyclization after steady-state load flow, cyclization, rupturing capacity scanning etc. calculates after Loop Closing Operation, finally, comprehensive
Above each calculated result is closed, the risk of involutive ring operation carries out comprehensive assessment, provides the possible out-of-limit letter of the Loop Closing Operation
Breath and security risk, whether safety provides conclusive information for involutive ring operation.By the function management and running, personnel can be comprehensive
Get information about the feelings such as rupturing capacity of the steady-state load flow of power grid, impact trend and breaker after closing the ring operates
Condition, involutive ring operation whether can carry out and cyclization after grid condition have one accurately hold.
The drawing road tagmeme table for drawing aid decision of rationing the power supply to read predefined automatically, draws in road tagmeme table and sets comprising La Lu
Standby title and corresponding operation switch, and the reasonability for defining content is examined automatically；When On-line Control, according to distant in real time
Measured data, it is automatic to calculate the minimal set that road object is drawn involved in excision load target value in conjunction with various target strategies；Really
After recognizing, Operation switch therein is all generated in combination remote control operation sequence, after reaffirming, into real time monitoring and intelligence
The mass-produced remote control operation that can be monitored.Each operational circumstances for drawing road or recovery are recorded in by data record and statistical function automatically
In historical data base, and is arranged, counted as required.
It is described that aid decision of rationing the power supply is drawn to improve the response speed drawn road and restore load control system when drawing is rationed the power supply
With safety and precise, the equilibrium of supply and demand of power grid can be fast implemented, has preferably ensured the stable operation of power grid, while also reducing
The probability of artificial maloperation.
Accident treatment decision failure decision includes that processing mainly turns including resultant fault analysis, scope of power outage analysis, load
Road is drawn for aid decision, single-phase earthing.
The method that the resultant fault analysis is combined using logic judgment with electrical quantity analytical algorithm, is accurately diagnosed to be
Fault element and nature of trouble in power grid identify protection and the breaker of malfunction and misaction, improve management and running personnel
The ability that catastrophic failure in power grid is handled.
The scope of power outage analysis is after power grid accident generation, and within the short time, dispatcher may be will receive largely
Abnormal accident is reported, and occurs a large amount of remote signalling displacement information in real-time monitoring system and stablize to get over limit information, weight in the short time
The information wanted can be fallen into oblivion by the mass data of presentation.In electric network composition complexity, it is difficult to the power failure model that discovery failure influences in time
It encloses.Scope of power outage is analyzed after receiving fault message, using local rapid topology, is analyzed network structure, is found out impacted stop
Electric range, while express statistic goes out facility information, is scheduled for operations staff's reference.
The analysis of load transfer aid decision combination resultant fault analysis as a result, provide the urgent plan of load restoration in time
Slightly, can it is significantly more efficient processing power grid accident development, shorten power system restoration operate normally time, reduce power grid accident
Bring loss.
Single-phase earthing draws road to be directed to distribution outlet singlephase earth fault, guarantee important load minimum according to loss load
Etc. principles, provide and road sequence drawn to suggest, and can be associated with remote control and carry out drawing dataway operation, voltage condition after monitoring operation judges
Whether single-phase earthing is eliminated, to analyze the route for determining single-phase earthing.
Embodiment more than original text is merely illustrative of the invention's technical idea, and protection model of the invention cannot be limited with this
Enclose, it is all according to the technical idea provided by the invention, any changes made on the basis of the technical scheme each falls within guarantor of the present invention
Within the scope of shield.The technology that the present invention is not directed to can be realized by existing technology.
