The flow process of the real-time line loss calculation methods that based on distribution on off state changed of the Fig. 1 to provide in the embodiment of the present invention Figure.The method of the present embodiment can be performed by the real-time line loss calculation device changed based on distribution on off state, and the device can Realize with by way of software, and can load in terminal unit.With reference to Fig. 1, the present embodiment provide based on distribution The real-time line loss calculation method of on off state change may include steps of:
S101, the CIM topological models for obtaining feeder line, and real time status information, the feeder line power transformation of the corresponding switch of feeder line That what is stood confesses the infeed electricity of electricity and transformator.
Specifically, electricity is obtained from each GIS (Geographic Information System, GIS-Geographic Information System) platform CIM (Common Information Model, the Common Information Model) topological model of the feeder line included in net, preferred feeder line It is power supply unit 10kV feeder lines.Also, the real-time status file of switch, feeder line transformer station are also obtained from distribution automation system The infeed electricity for confessing electricity and transformator.
In view of generalized information system per se with certain Network topology function, the electricity distribution network model based on geometric network GIS and distribution net topology can be combined, moreover it is possible to Topology Analysis of Power Distribution Network is optimized using the topology of generalized information system, Also eliminate the process of the original annexation of manual typing of loaded down with trivial details in the past and easy error.GIS is utilized in order to follow-up S102 The model file of platform parses electrical network static topological relation.
S102, parsing CIM topological models, the switch included in obtaining the corresponding all paths of feeder line and each path.
Specifically, the description information of each feeder line in CIM topological models is parsed, static power grid topological relation is obtained, specifically, For each feed line, the switch included in obtaining the corresponding all paths of the feeder line and each path.
With reference to Fig. 2, S102 can include:
S102-1, the corresponding description file of CIM topological models for obtaining feeder line.
Specifically, it can be XML (eXtensible Markup Language, extensible markup language) literary to describe file Part, described in which, file can be corresponded with feeder line, and a description file can also include the description information of multiple feeder lines.
S102-2, matched in description file according to the naming rule of feeder line transformer station, determined feeder line transformer station.
As the naming rule of feeder line transformer station in CIM topological models is " Circuit rdf:ID=" CIRCUIT_ ", therefore Key word " Circuit rdf are searched in description file:ID=" CIRCUIT_ ", determine that feeder line becomes the numbering of electrical equipment.
S102-3, lookup description file determine the outlet switch of feeder line transformer station, and travel through two of outlet switch respectively Two paths that port is located.
Specifically, by key word " Circuit.SourceBreaker " being searched in description file, obtain feeder line power transformation The outlet switch stood, i.e. feeder line transformer station it is corresponding first switch, record its numbering, and make number of switches value be 1.It is logical Cross two ports that key word " Terminal.ConductingEquipment " finds outlet switch are searched in description file, Correspondingly numbering and switch number that the feeder line for having recorded becomes electrical equipment are replicated one time, the Liang Tiaolu that two ports are located is obtained Footpath.Subsequently, two paths that two ports for beginning stepping through outlet switch from port outlet respectively are located.
S102-4, determine with the presence or absence of setting control in each path, and according to determining that result determines path and path in Switch.
Wherein setting control includes switch, Transformer Winding (TransformerWinding) and the AC line of setting type Section (ACLineSegment), the switch for setting type include chopper (Breaker), on-load switch (LoadBreakSwitch) With disconnecting switch (Disconnector).
Specifically, during two paths that two ports of traversal are located, by searching key word " Terminal.ConnectivityNode " finds attribute identical other controls, and whether has setting in determining other controls Control.If there is no setting control in other controls of either path, illustrate that the path is dead end, terminate the path and eliminate Corresponding record;If having m (m in his control arbitrary>=1) individual setting control, then replicate the record in the path m-1 time, and hold Row is following to be operated:If set control recording the numbering of the switch to set the switch of type, Slate k+1;If setting control To exchange line segment, then continue to carry out traversal path operation from another port of exchange line segment;If set control as transformator around Group, then using Transformer Winding as respective path terminal, record path numbering, terminate the traversal in this path.
S102-5, each paths travel through at the end of, if terminal is Transformer Winding, record the corresponding feedback in the path The state of line mark, transformer identity, switch mark and switch.
S102-6, the switch by including in the form all paths of storage and each path of linear directory.
Exemplary, when the switch included in all paths and each path is stored by the form of linear directory, will Feeder line transformer station and transformator in path is stored in same table, by switch storage in another table, and by linear Two tables are associated by index.
For example, the feeder line transformer station in path and transformator information are stored in Table A, and switch is stored in table B, and built Both is coupled together by vertical linear directory, and in form, n refers to the change total degree of on off state.
The form of wherein Table A is following (only having first three to show data at present):
Wherein the form of table B (only has first two columns to have data) as follows at present:
In every paths, head node (feeder line transformer station) and tail node (transformator) are all unique, and intermediate controls (switch) is not fixed number, and this causes path different in size, according to the direct sub-path record of method of sequential storage, then will Have big quantity space not store anything and cause the waste in space, the present invention is stored by way of using linear directory Path data, saves memory space.
S103, the real time status information based on switch, obtain all paths and power relationship change information.

S103-2, according to the real-time status of all switches in each path, determine the real-time connected state in each path.
For each path, determine the path each according to all switches on the path in the real-time status of each time point The real-time connected state of time point.For example, with reference to Fig. 2, " logical AND " computing is carried out to the state of all switches in each time point, And result of calculation is added to into path in Table A in the state of correspondence position.If result is 1, all switches on path are illustrated For closure state, path is now path;If result is 0, path is open circuit.
If S103-3, the real-time connected state for detecting either path are different with upper one real-time connected state, it is determined that The power supply relationship change in the path, and record real-time time and state.
With reference to Fig. 2, specifically, if during any time point, detecting real-time connected state and the path of either path (it is to connect for example to go up a real-time connected state to upper one real-time connected state difference, the real-time connection that the time point is detected State is to disconnect, or upper one real-time connected state is to disconnect, and the real-time connected state that the time point is detected is connection), Then determine that the path occurs power supply relationship change in the time point, and record the state in the time point and the corresponding path.
If it should be noted that any time point is first run time point, recording the power supply relation in each path, will The corresponding state of run time point is inserted in 0 hurdle of state of table B for the first time.By that analogy, if current real-time status data is added to In the row of " state K ", then be added to " state K% (n-1) " row next time.Wherein n is not less than 2, it is contemplated that Practical Calculation Speed might have delay, it is possible to which appropriate increase n stores the state at multiple moment.
Specifically, for example in first time point, corresponding is first time period state, so by the shape in Table A State 0 is recorded in table C.
The form of wherein table C is as follows:
S104, according to the infeed electricity for confessing electricity and transformator of feeder line transformer station, and all paths power relation Change information, determines the real-time line loss of feeder line.

Exemplary, S104 can include:
S104-1, the corresponding all paths of acquisition feeder line.
Specifically, for each feeder line, the corresponding all paths of the feeder line are obtained from the Table A of S102.
S104-2, the infeed electricity for confessing electricity and transformator of foundation feeder line transformer station, determine feedback in target time section The infeed electricity for confessing each transformator on electricity and corresponding each path of line transformer station.
Specifically, calculating (tt in certain period to a certain feeder line1To tt2) line loss, with reference to the electricity number obtained in S101 According to calculating tt1To tt2In corresponding target time section, the infeed for confessing each transformator on electricity GC and path of feeder line transformer station Electricity GR1、GR2、……、GRN, wherein N is the sum for becoming electrical equipment on the path of the feeder line.
However, as the interval of the electric quantity data that can actually obtain is not necessarily tt1To tt2, then can be accounted for interval It is than calculating power consumption, specific as follows:
It is determined that the period for confessing electricity of the transformer station that can be obtained is t1~t2And t2~t3, and transformer station is t in the period2 ~t3Confess electricity for C2
If t1<=tt1<tt2<=t2, then feeder line transformer station is in time period (tt1To tt2) in the electricity GC that confesses be:
If t1<=tt1<t2<tt2<=t3, then feeder line transformer station is in time period (tt1To tt2) in the electricity GC that confesses be:
By that analogy, according to the interval of the electric quantity data that can actually obtain, feeder line transformer station can be obtained in target area It is interior to confess electricity GC.
