Compared with the prior art, the invention is mainly characterized in that: the method has the advantages that the ring network diagram meeting the requirements of the dispatching dispatcher is automatically generated by automatically generating the ring network diagram by means of an algorithm and automatically analyzing the topological relation of the line according to a real-time data source, various user customization schemes are supported, the generation speed and the accuracy of the ring network diagram are greatly improved, meanwhile, the ring network diagram after the line is changed is automatically maintained, the ring network diagram is automatically issued, the real-time performance is greatly improved, and the working efficiency of the dispatching dispatcher is improved.
The looped network drawing generation method comprises the following steps:
For example, if there are 6 transformer stations and 6 user terminals, the 6 transformer stations are sequentially labeled as a1, a2 … …, and a6, and the 6 user terminals are sequentially labeled as: y1, Y2, … …, Y6, respectively, determine the picture elements of the transformer station and the user terminal, such as the transformer station and the user terminal are represented by different graphics.
And 200, sequentially controlling the power-on condition of each transformer according to the load power supply control relation of the distribution ring network, automatically analyzing the topological structure of the transformer station, and determining the annular connection relation of the transformer station according to topological logic information.
For example, there are 6 transformer stations in the distribution ring network of the present embodiment, which are arranged in sequence according to the reference numbers 1, 2, 3, 4, 5, and 6, and supply power to the distribution ring network, and then, with the user side supplied by the transformer station with the reference number 1, the power supply of the user side specifically includes the transformer station with the reference number 1, the transformer station with the reference number 6 located on the left side of the transformer station with the reference number 1, and the transformer station with the reference number 2 located on the right side of the transformer station with the reference number 1, so that the energization condition of each transformer is sequentially controlled according to the load power supply control relationship of the distribution ring network, and the topology structure of the transformer stations can be automatically analyzed.
Regulating and controlling the power-on and power-off sequence of all transformer stations in the distribution ring network, determining the connection relation of the transformer stations in the distribution ring network according to the characteristic that a load in the distribution ring network has two paths of power supplies, and constructing a connection relation algorithm of the transformer stations, wherein the specific steps are as follows:
step 201, setting an external circulation parameter at a transformer station, setting an internal circulation parameter at a user side, electrifying the transformer station numbered first, and completely pausing the electrification of other transformer stations to keep a ring network switch cabinet in a power distribution ring network to be in an open state.
The total cycle number of the outer cycle parameters is specifically the number of the transformer stations, the inner cycle parameters are specifically selected according to the electrified label sequence, the specific cycle mode is that the user side label rule normally used when one transformer station is electrified is obtained according to the current electrified cycle parameters +/-1, and the connection relation between the transformer stations is reflected through the user side numbering rule.
Step 202, matching the power supply relationship between the electrified transformer station and the user side according to the load power supply control relationship of the distribution ring network, determining the transformer stations adjacent to the electrified transformer station, and grouping the transformer stations with the determined connection relationship.
When the transformer stations adjacent to the electrified transformer station are determined, the electrified transformer station is located in the middle, and the two transformer stations connected with the electrified transformer station are divided into two sides of the electrified transformer station.
That is, when the transformer station with reference number 1 is powered on, all other transformer stations are powered off, and only the user terminals with reference numbers 6, 1 and 2 can normally supply power, so that the transformer stations with reference numbers 6, 1 and 2 form a power-on association group.
And 203, the serial numbers of the transformer stations are recycled, the transformer stations with the serial numbers are electrified, other transformer stations are all electrified in a pause mode, and the ring network switch cabinet in the power distribution ring network is kept in an opening state.
And 204, matching the power supply relation between the electrified transformer station corresponding to the number and the user side according to the load power supply control relation of the distribution ring network, and determining that the transformer stations in the three adjacent connection relations form a group.
Similarly, when the transformer station with the reference number 2 is powered on, all other transformer stations are powered off, and only the user terminals with the reference numbers 1, 2 and 3 can normally supply power, so that the transformer stations with the reference numbers 1, 2 and 3 form a power-on association group.
And step 205, repeating step 203 and step 204 until the situation that the unconnected transformation stations are connected is determined, and generating a plurality of groups of links integrating three transformation stations.
The circulation times are determined according to the number of the transformer stations, the transformer stations with the numbers of 1, 2, 3, 4, 5 and 6 are sequentially electrified, and other transformer stations are sequentially disconnected, so that the transformer station electrified links with the numbers of 6, 1 and 2, the transformer station electrified links with the numbers of 1, 2 and 3 and the transformer station electrified links … … with the numbers of 2, 3 and 4 can be formed, the topological structure of the power distribution ring network can be automatically analyzed, and the electrified incidence relation of the transformer stations can be obtained.
Therefore, in the above steps 201 to 204, through a cyclic algorithm, one transformer station is sequentially selected to be powered on, other transformer stations are powered off, and user side information of normal power supply at this time can be obtained according to the power relation of ring network power distribution, so that the power-on links of the transformer stations are determined to obtain 6 power-on links of the transformer stations, the transformer station links are 3 associated transformer stations, and the 6 power-on links of the transformer stations need to be further connected in sequence to form a connection line band.
And 300, automatically generating a 10 kV line ring network diagram of the power distribution network according to the annular connection relation of the transformer stations.
That is to say, after a plurality of links integrated by three transformer station groups are generated, the plurality of links need to be sequentially connected to form a ring network line, and the specific steps of sequentially connecting the links are as follows:
and 301, connecting two links with the same transformer station in a superposed manner to form a connecting line band.
In the present embodiment, that is, when the transformer station power-on links denoted by 6, 1, and 2 are connected to the transformer station power-on links denoted by 1, 2, and 3, the transformer station power-on links denoted by 6, 1, 2, and 3 are formed, and by analogy, the connection line zones denoted by 6, 1, 2, 3, 4, and 5 are formed end to end.
And 302, determining the diameter of an annular ring according to the number of the transformer stations, and circularly arranging the connecting line bands on the annular ring through an annular array, wherein the diameter of the annular ring is in direct proportion to the number of the transformer stations.
This step is to determine the uniformity of the transformer stations as they are distributed in the endless web.
And 303, overlapping and connecting two links with the same transformation station at two ends of the connecting line belt to form a ring network diagram meeting the requirements of a dispatching dispatcher.
And step 400, adding a looped network circuit of the transformer station, automatically maintaining circuit change according to topology logic information of power-on control of the transformer station, and regenerating a looped network diagram.
When the ring network line is determined again by adding a new transformer station,
in step 400, the specific steps of determining the ring network line of the newly added transformer station are as follows:
step 401, determining a logical relationship between the newly increased transformer station and the power supply of the user side, and matching the power supply relationship between the newly increased transformer station and the power supply of the user side.
For example, if a new transformer station is added, only an algorithm needs to be added to energize the new transformer station to determine the supply relationship between the transformer station and the original user terminal.
And 402, determining the original transformer station adjacent to the newly-added transformer station, and generating a new connecting line band.
After the supply relationship between the transformer stations and the original user terminals is determined, the installation position of the new transformer station can be determined, namely, the new transformer station is arranged between the transformer stations of the two original user terminals, and other positions of the original transformer stations are unchanged to generate a new connecting line band.
And 403, adaptively changing the diameter of the annular ring according to the number of the transformer stations, and rearranging all the transformer stations on the annular ring in an annular array manner to obtain the looped network diagram after the circuit is newly added.
After the new transformation stations are added, the total number of the transformation stations is increased, the diameter of the annular ring is increased, and the transformation stations are arrayed in an annular mode again to generate a new ring network diagram.
Obviously, the ring network circuit updating method of the invention is simple and convenient, and the ring network diagram can be updated only by adding the newly-added transformation station into the original ring network diagram and readjusting the position of the transformation station of the ring network diagram, rather than performing logic analysis on the transformation station again, so that the operation mode is reduced and errors are avoided.
In addition, when the ring network circuit is updated, the transformer stations are also cancelled, the transformer stations are reduced, and a new ring network circuit condition is generated, wherein the specific step of updating the ring network circuit diagram comprises the following steps:
(1) re-labeling the rest of the deactivated transformer stations, and corresponding the transformer stations to the new labels one by one;
(2) repeating the operation of the step 201 to the step 204, and updating the electrifying topological relation of the transformer station;
(3) and overlapping and connecting the new links to generate a new ring graph.
When the transformer station is updated, the influence of the logic relationship is large for canceling the original transformer station, and the looped network diagram is reconstructed, so that the stability and the accuracy of the looped network diagram construction can be ensured.
