The technical solution adopted for the present invention to solve the technical problems:
This operation ticket system comprises the operation order generation module, line chart graphics module etc.Wherein, the operation order generation module comprises automatic invoice issuance again, manual bill, graphic modeling demonstration, functions such as procedure audit.
1. the generation of operation order
The generation of operation order is the process of a more complicated.The generative process of operation order has comprised network topology, traversal mode, the integrated use of working rule etc.The generating run ticket has dual mode: generate automatically and manual the generation.Native system has automatic one-tenth ticket and the function that manually becomes ticket simultaneously.Below introduce the generative process of native system operation order from four aspects.
(1) topological model of line chart
Equipment in the power distribution network comprises switch, disconnecting link, controlled distribution box, ring main unit, substation transformer etc.These equipment just are expressed as pel one by one on line chart.And the equipment in the power distribution network contains numbering, title, and electric pressure, whether rated current attribute such as disconnects.How expressing pel, is the problem that we must consider.
The OO representation of knowledge is a kind of desirable representation of knowledge form, and it can describe static characteristics, dynamic behaviour and the interaction of complex object easily based on abstract data type, has the advantage of general knowledge representation concurrently.What native system adopted is exactly the object-oriented representation method, and the pel in the line chart is abstracted into class, numbering, and whether title the attribute of attribute as class such as disconnects.Like this, when the state that changes equipment, as with switch when closure state transfers off-state to, only need to change an attribute of switch, express very simple and convenient.
For the problem that whether is necessary all pels in the line chart all are abstracted into class in the native system, we find, each sequence of operation only relates to switch in the operation order, disconnecting link, controlled distribution box, 4 kinds of primary equipments of ring main unit, and attached disconnecting link, secondary devices such as ground connection disconnecting link, and controlled distribution box, ring main unit finally also can be decomposed into the operation of disconnecting link and switch, and promptly various operation tasks only need relevant switch, disconnecting link and secondary device are operated and can be finished.Therefore, will bus and primary equipment such as transformer be abstracted into class separately, but only switch abstract be 1 class, be other 1 class with disconnecting link is abstract.Because the operation of various secondary devices, as " disconnecting the attached disconnecting link of so-and-so switch " etc., all be as the replenishing or cooperate of switch and switch operation, in order to carry out efficient reasoning, so all secondary devices are encapsulated in the corresponding primary equipment class as data member, and are not abstracted into class separately.
The annexation of equipment is that the topological model of line chart is the major issue that must consider in the line chart.Topological model is concerning the quality of the speed and the algorithm of speed when traveling through.Owing to be stored in the database by the geography information of measuring equipment such as coordinate, the coordinate of native system by equipment on line chart, draw automatically in the power distribution network equipment and carry out topological initialization.If judge that through program topological initialization is correct, effectively, then the initialized result of topology is write database.In database, stored the numbering of pel, information such as current direction.
(2) from the order of operation phrase generating run
Manual generating run ticket is finished by a graphic operation in the native system.The operation of native system equipment is divided into simple operations and complex operations.Simple operations comprises cut-off switch, and Closing Switch hangs up warning sign etc.Complex operations comprises the transhipment row, changes standby, changes maintenance etc.Complex operations can be decomposed into some simple operationss through after the analysis of program.When the user has selected an equipment, when clicking right-click menu, thereby program can be judged attributes such as the type of this equipment and states and shows corresponding menu.As selected the switch of a closure, click right-click menu.Program is through demonstrating menus such as " cut-off switch change standby, changes maintenance " in right-click menu after certain judgement.The menu has here mainly shown operational motion, does not show about the out of Memory of equipment pel.When having clicked some actions menus, system can obtain the title of equipment, and then obtain the ring or the circuit at equipment place according to the numbering of the equipment of selection, thus the generating run order.Operational order is by operation verb, line name, device name, four compositions of device type.
In addition, because certain, some operation is difficult to generate by a graphic operation, at this moment can generate by inserting operational order in the form of operation steps.The method of inserting operational order is: inserts operational order when clicking menu, can eject forms, in forms, select to want the ring at apparatus operating place, and device name, initial state, final states can the generating run order.
(3) the anti-misinterpretation of each step command
Computer generation not only will improve and intend ticket efficient for people's formulation operation order, also will improve the accuracy of intending ticket.Therefore, in operation ticket system, whether successful the operation order correctness of leaving be one of this system essential condition.Therefore, operation order is prevented that misinterpretation is essential.For the anti-misinterpretation of operation order, must be according to the working rule of power distribution network.Can not the on-load drawing as disconnecting link, switch and attached disconnecting link thereof disconnect and certain sequence of operation etc. are being arranged when closed.
(4) automatic generating run ticket
The automatic generating run ticket of system is a comprehensive stronger job.In the process of generating run ticket, need to consider network topology, factors such as inference mode.Here, imitate the mode that the expert ponders a problem.At first consider the sequence of operation of primary equipment, and then add the operation of people's secondary device that such knowledge arranges system succinct, clear, lucid and lively.
2. the realization of working rule template
An operation order is according at particular device and specific operation task, according to the power distribution network working specification, changes the operational order collection of relevant devices running status according to the operational term of standard.Therefore, can think operation order by operand, operation task, working rule, operational term constitutes.Wherein, operand comprises all exercisable primary equipment and secondary devices in the power distribution network, all operations that circuit and equipment are carried out in the operation task assignment electrical network, the standard that should follow when working rule refers to carry out some operation, operational term refers to the expression way of these operations.Wherein, working rule has in operation order and important effect.Working rule is a basic strategy of guaranteeing electric power netting safe running, and the formulation of guiding operation order need combine closely with real-time electric equipment operation situation and power network wiring mode, protection.
Because the complex structure of power distribution network, the formulation of working rule and a constantly perfect major issue that becomes operation ticket system.For this reason, native system proposes a kind of working rule template of layering, and is corresponding with inhomogeneous operation of equipment rule.Simultaneously, this working rule template can be safeguarded by the user.
The working rule template is divided into circuit by device type, switch, disconnecting link, controlled distribution box, ring main unit five classes.Wherein, every class is pressed operation task again, relevant device, and initial state, final states is divided.
After having designed the working rule template, the user can be according to the characteristics customized rules template of power distribution network, and formation rule storehouse sacrificial vessel body equipment is quoted.System provides selection equipment on wiring diagram, formulates the function of operation task, and program can be carried out topological analysis according to operation task, seeks associated connections and equipment, and carries out reasoning by working rule, finally generates consistent satisfactory operation order.No matter be simple operations task or complex operations task, can both dynamically generate corresponding rule base, and dynamic operation rule template technology is easy to the modification of implementation rule and perfect, improved the versatility of system with rule template.
The present invention adopts OO expression way, and the primary equipment that needs in the line chart to operate is abstracted into class, simultaneously the data member of secondary device as class is encapsulated in the class.In addition, adopt the dynamic template rule, be easy to user's modification.Simultaneously, native system has also been realized sharing real time data with the SCADA system, and automatic invoice issuance or manual the click are made out an invoice, and the good anti-misinterpretation and the function of analog demenstration.
Referring to Fig. 1, native system is made up of operation order generation module, line chart graphics module, system maintaining module three big modules.
System maintaining module and database server link together closely, can be to carrying out suitable operation with the closely-related operation order thesaurus of native system, working rule storehouse, electric network information storehouse, user information database, since satisfy the real time altering of required various information in the native system.The dynamic operation rule template technology that is adopted in the maintenance to the working rule storehouse particularly just is easy to the modification of implementation rule and perfect more, thereby has improved the versatility of total system greatly.
The line chart graphics module is a supplementary module of native system, and it is finished every function for total system a basic platform is provided, and also allows total system more simple and easy to do.
The operation order generation module is the nucleus module of native system, and it has automatic invoice issuance, figure preview, manual bill and four functions of procedure management.Automatic invoice issuance and manual bill complement each other, and finish the generation work to all operations ticket jointly.Figure is previewed then let us and is more clearly recognized after the executable operations the influence that each equipment produced and some problems that wherein may exist.Procedure management then allows the generative process accurate and effective more of whole operation ticket.The operation order generation module also is connected with the SCADA system by the system coordination module, real time data shared with it, the real-time benefit of lifting total system.
Referring to Fig. 3, what this figure showed is the flow process of automatic generating run ticket among the present invention.The mode that this flow process imitation expert ponders a problem, when the operation task that system obtains being submitted to by the user, the automatic analysis operation task of system's meeting, and the formation equipment relevant and the subsystem of state thereof with operation task, and then form the network chart of this subsystem, our state of manual amendment's relevant device as required to make things convenient for next step to reasonings that equipment was carried out such as switch, disconnecting links, is exported a complete operation order at last therein.After obtaining operation order, the user can carry out analog demenstration in native system, if pinpoint the problems and can correct, confirms just operation order to be printed after errorless in analog demenstration.
Intend the accuracy of ticket in order to improve computing machine, operation order is carried out anti-misoperation then be absolutely necessary.Referring to Fig. 2, enter after the determination flow, whole defence judgement just divides for three kinds of situations:
