Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, in an embodiment of the present invention, a distribution network scheduling instruction ticket security checking method based on a traversal tree is provided, where the method includes the following steps:
s1, acquiring a single-line topological graph of the distribution network, and generating the acquired single-line topological graph of the distribution network into a simplified model; wherein the simplified model contains only specified elements, and the specified elements include buses, lines, transformers, switches, and disconnecting links; (ii) a
The specific process is that the topological structure of the distribution network in the power system is often presented in a single line diagram mode, key information equipment (such as buses, switches, disconnecting links, lines and transformers) in the single line topological diagram of the distribution network is read, and a simplified model only containing specified elements is generated. The designated elements are key information devices in a single-line topological graph of the distribution network, and specifically comprise elements such as buses, switches, disconnecting links, lines and transformers.
It should be noted that each designated element has a unique ID in the simplified model. For example, BUS lines { BUS 1-BUSn }, switches { QF 1-QFn }, switches { QSn }, lines { L1-Ln }, and transformers { TR 1-TRn }.
In the simplified model, each designated element determines other elements connected with the designated element through connection attributes, or each designated element determines a real-time working state through state attributes, so related attributes of each designated element need to be predefined. For example, the state attribute of each switch is preset to be one of a running state, a hot standby state, a cold standby state and a maintenance state, and the connection attribute of each switch is double connection; presetting that the state attribute of each disconnecting link is one of an operating state, a hot standby state and a maintenance state, and the connection attribute is double connection; presetting that the connection attribute of each bus and each line is double connection; and presetting that the connection attribute of each transformer is single connection.
That is, the above-mentioned specified elements are of three types; wherein the first type includes double-connection state type elements such as switches and disconnecting links, the second type includes double-connection non-state type elements such as buses and lines, and the third type includes single-connection non-state type elements such as transformers. At this time, the state attribute of the switch is one of the following: 0-run state; 1-hot standby state; 2-cold standby state; 3-maintenance state; the state attribute of the knife switch is one of the following: 0-run state; 1-hot standby state; 2-maintenance state.
Step S2, acquiring distribution network dispatching instruction ticket simulation operation of a user on the single-line topological graph of the distribution network according to the maintenance list, obtaining a maintenance topological path formed after the user simulation operation and state attributes of switches corresponding to the simulation operation based on the simplified model, and further forming a temporary switch library according to the switches of the simulation operation and the corresponding state attributes;
the specific process is that a user makes a distribution network dispatching instruction ticket according to the maintenance list, and at the moment, the simulation operation of the user on the distribution network according to the maintenance list can be displayed on a single-line topological graph of the distribution network. Because the single-line topological graph of the distribution network is simplified to obtain a simplified model, a maintenance topological path formed after user simulation operation and state attributes of each switch corresponding to the simulation operation are obtained on the simplified model, and the system temporarily stores the state attributes of each switch in the simulation operation to form a temporary switch library.
It should be noted that when a user creates a distribution network scheduling instruction ticket according to a maintenance order, the state attribute of each switch of the simulation operation is converted into a maintenance state. Of course, if a distribution network scheduling instruction ticket made by a user misses a switch in the maintenance topology path, the missing switch continues to maintain the original state attribute (such as a hot standby state) in the simulation operation process, and the state attribute is not converted into the maintenance state, which may cause a phenomenon that the scheduling instruction ticket is unsuccessfully checked. Or, when the user performs the distribution network scheduling instruction ticket simulation operation, the state attribute of a certain switch in the overhaul topology path is not converted, that is, the original state attribute (such as the running state) is continuously maintained, which may also result in the unsuccessful checking of the scheduling instruction ticket.
Step S3, detecting whether the state attribute of each switch in the temporary switch library conforms to the preset attribute;
the specific process includes that in view of avoiding that the state attribute of a certain switch in an overhaul topology path is not converted during the simulation operation of the distribution network scheduling instruction ticket, the state attribute of each switch in the temporary switch library needs to be detected, and whether the state attribute of each switch in the temporary switch library meets the preset attribute (such as the overhaul state) is detected. It should be noted that the predetermined attribute may be set according to a specific service work schedule, and that the predetermined attribute is one of predefined switch status attributes.
Step S4, if it is detected that the state attribute of at least one switch in the temporary switch library does not accord with the preset attribute, obtaining the conclusion that the checking is unsuccessful, and outputting first warning information.
The specific process is that if the state attribute of at least one switch in the temporary switch library is detected to be not in accordance with the preset attribute (such as the overhaul state), a conclusion that the checking is unsuccessful is obtained, and first warning information is output. The first warning information is that the ground fault is not checked if the analog operation switch is not closed. It is understood that the first alarm information may carry a switch ID that specifically detects non-compliance with the predetermined attribute.
Step S5, if it is detected that the state attributes of the switches in the temporary switch library all accord with the preset attributes, sequentially extracting each switch from the temporary switch library, traversing in the search direction formed in the obtained overhaul topological path according to a preset rule by taking the extracted switch as a starting point until any boundary condition in a preset boundary condition combination is reached, finishing the traversal, obtaining a conclusion that the verification is successful or a conclusion that the verification is unsuccessful according to the corresponding boundary conditions that all the switches in the temporary switch library finish the traversal, and outputting second alarm information when the conclusion that the verification is unsuccessful is obtained.
Specifically, when the state attributes of all the switches in the temporary switch library all meet the predetermined attribute (for example, 3-maintenance state), the first switch is sequentially selected from the temporary switch library, the selection sequence may be a sequencing mode of the temporary switch library from left to right or from right to left, and topology traversal is performed according to the following mode:
(1) and traversing the selected switch in the search direction formed in the obtained overhaul topological path according to a preset rule.
The search direction is set by taking the switch extracted from the temporary switch bank as a reference point in the obtained overhaul topological path and according to the direction of the closest bus connected with the reference point pointing to the reference point, namely the bus is in the switch direction.
(2) Determining whether the current traversal reaches any boundary condition in a preset boundary condition combination; if yes, ending traversal; if not, continuing to traverse downwards along the search direction.
The preset boundary condition combination comprises a first boundary condition, a second boundary condition, a third boundary condition and a fourth boundary condition. The first boundary condition is that if the switch is traversed along the search direction and the corresponding state attribute meets the preset attribute (such as the maintenance state), the traversal is finished. The second boundary condition is that if the transformer is traversed along the search direction, the traversal is finished. The third boundary condition is that if any one of the bus, the line, the transformer, the switch and the disconnecting link cannot be traversed along the search direction, the traversal is finished. And the fourth boundary condition is that if the switch in the substation is traversed along the search direction and the corresponding state attribute does not accord with the preset attribute (such as a non-overhaul state), the traversal is finished. It should be noted that the fourth boundary condition is suitable for a case where a distribution network scheduling instruction ticket made by a user misses a switch in the maintenance topological path, and at this time, a switch in the substation may be located in the maintenance topological path or a search direction path outside the maintenance topological path.
Namely, the first boundary condition is that the switch is in a maintenance state, and the round of traversal is finished; the second boundary condition is that the round of traversal is finished when the transformer and other single-connection non-state elements are met; the third boundary condition is that the back end has no connectionless element (i.e. no one of the specified elements), and the round of traversal is finished; and the fourth boundary condition is that the transformer substation is traversed to the switch in the transformer substation (namely the switch in the 10kV feeder station) and the switch in the transformer substation is in a non-overhaul state, and the round of traversal is finished. Therefore, the following conditions for continuing the traversal can be obtained, specifically including: if the circuit is encountered, the circuit is continuously traversed; when the switch and the disconnecting link are in a non-maintenance state, the traversing is continued; when the bus is encountered, the bus is traversed continuously; when the switch is in hot standby and cold standby, the traversal is continued.
And secondly, sequentially reselecting the switches which are not traversed in the temporary switch library and continuously traversing according to the steps (1) to (2) until all the switches are finished.
And finally, after all the switches in the temporary switch library are traversed, if the corresponding boundary conditions of all the switches in the temporary switch library, which finish traversing, are any one of the first boundary condition, the second boundary condition and the third boundary condition of the preset boundary condition combination, obtaining a conclusion that the checking is successful. Or
And after all the switches in the temporary switch library are traversed, if the corresponding boundary condition of at least one switch in the temporary switch library for finishing traversing is the fourth boundary condition of the preset boundary condition combination, obtaining a conclusion that the checking is unsuccessful, and outputting second alarm information. And if the second alarm information indicates that the safety measures are insufficient, whether the power supply side switch is not operated is checked, and the check is failed.
It should be noted that the advantages of using the above traversal algorithm are mainly to prevent the following situations: (a) omitting safety measures, and not doing the safety measures at the incoming call side of the working point; (b) the single radiation branch has only one incoming side; (c) the incoming side has safety measures and a switch in a maintenance state also exists in a working range; (d) a single networked switch appears.
As shown in fig. 2, it is a flowchart of the traversal algorithm corresponding to steps S3 to S5. Wherein the content of the first and second substances,
firstly, all the switch states in the temporary switch library are required to be in maintenance states, and if the switch is not in the maintenance state, an alarm 1 is directly sent out.
Secondly, selecting a first switch a1 from the temporary switch library A, traversing downwards by the switch (the downward traversal refers to the traversal of the switch to the line side), and continuing the traversal if the line is encountered; if the switch and the disconnecting link are in a non-maintenance state, continuously traversing; if the bus is encountered, continuously traversing; if the switch is in hot standby and cold standby, the traversal is continued.
Once the switch in the station is traversed to the switch in the 10kV feeder line station and the switch in the station is in a non-maintenance state, the round of traversal is finished, and an alarm 2 is sent out; when the switch is in a maintenance state, ending the round of traversal; the rear end of the switch is not provided with a connecting element, and the round of traversal is finished; the traversal encounters a single-connection non-state element (transformer), ending the round of traversal.
And finally, selecting other switches which are not traversed in the temporary switch library, and continuing traversing until all the switches are finished. If the maintenance state switch is not the operation switch, recording abnormal information; and if the indoor switch is traversed to the indoor switch and the indoor switch is not in the maintenance state, recording abnormal information.
As shown in fig. 3 and fig. 4, an application scenario of the distribution network scheduling instruction ticket security checking method based on the traversal tree in the embodiment of the present invention is further explained:
fig. 3 is a single-line topological diagram of a distribution network composed of two 10kV lines, a first 10kV feeder line is a 10kV first line F01 of an a substation, and a second feeder line is a 10kV second line F02 of a B substation. Fig. 4 is a simplified diagram of fig. 3, only the bus, switches, knife switches, lines, and transformer components being retained. Wherein, the designated elements can be divided into three categories:
the first type: 0-double connection state type element
Switch model (QF): switch state attribute 0-run; 1-hot standby; 2-cooling for standby; 3-maintenance
Knife gate model (QS): the state attribute of the disconnecting link is 0-operation; 1-hot standby; 2, overhauling;
the second type: 1-double connection non-state type element
BUS model (BUS), LINE model (LINE)
In the third category: 2-single connection non-state type element
A transformer model (TR);
each element has a unique ID in the figure, and each element determines the element connected to it by a connection attribute.
And the elements are named and expressed uniformly in sequence, namely, the designated elements are contained in FIG. 4: BUS { BUS 1-BUS 5}, switches { QF 1-QF 15}, switches { QS1}, lines { L1-L5 }, and transformers { TR 1-TR 4 }.
Example 1:
first boundary conditions: and when the maintenance switch is met, the traversing is stopped.
The work content of the maintenance list is as follows: the line work is carried out between the switch # 3 of the #2 power distribution cabinet and the switch # 2 of the #1 ring main unit.
Safety measures of the maintenance list: the #2 switch cabinet # 3 switch and the #1 ring main unit # 2 switch are all rotated to be overhauled, and the incoming call side safety measures of a working place are guaranteed to meet.
(I) And the dispatcher performs simulation operation according to the single-line topological graph of the distribution network of the maintenance list, and converts the state attributes of the two switches into maintenance conversion states in the simplified model.
(II) forming a temporary switch bank a ═ { a1, a2} in which a1 ═ QF8 and a2 ═ QF9, from the switches operated in analog.
And (III) checking whether all the state attributes of all the switches in the temporary switch library A are in the maintenance state, wherein the checking result is yes.
