Description

Technical Field

[0001] The present invention relates to the field of traction power supply technology, and in particular to a method, system, electronic device and storage medium for collaborative control of power supply arm switch equipment based on an automatic matching algorithm. Background Art

[0002] In the railway traction power supply system, the construction and maintenance of the overhead contact network and related equipment usually require the train dispatcher to reserve a specific time period in the train operation diagram, namely the "window point". During the window point, no train operation will be arranged to ensure a safe working environment for construction and maintenance personnel. The operation process of the window point mainly includes: the power dispatcher performs the power outage operation, the construction personnel enter the site to start the operation, and after the operation is completed, the construction personnel notify the dispatcher to restore the power supply. However, if the dispatcher takes too long in the power outage process, the actual available operation time will be shortened accordingly. Sometimes, it is even impossible to complete the established task within the scheduled window time, and then it is necessary to reapply for a new window point, which directly affects the efficiency of the use of the window point.

[0003] In order to improve the utilization efficiency of the skylight points and reduce the above risks, the existing technical means mainly compile all the remote control commands of the switchgear related to the power supply arm power outage into a special power supply arm power outage card according to their execution order. During the skylight point, the electrician selects the corresponding card according to specific needs, and then the automation program automatically executes the operation of the switchgear according to the preset instruction sequence in the card. Although this method improves the work efficiency and safety to a certain extent, it still has the following shortcomings:

[0004] There is still a risk of the electrician selecting the wrong card in actual operation, which may lead to incorrect power outage operation, thus affecting the safety and efficiency of the operation;

[0005] When it is necessary to cut off the power supply to multiple power supply arms at the same time, since only one card can be executed at the same time, the whole process still takes a long time, which limits the full utilization of the skylight points;

[0006] For some power supply arms, the order of power outage and power supply operations has strict requirements. If the electrician fails to accurately follow these orders to perform operations, it may cause the failure of power outage and power supply operations, further affecting the smooth implementation of the operation plan;

[0007] The above problems indicate that although the existing technical solutions have optimized the power outage operation process within the skylight points to a certain extent, there are still technical problems such as erroneous operations caused by human factors and low power outage efficiency. Summary of the invention

[0008] In order to improve the efficiency of power outage and avoid erroneous operations caused by human factors, the present invention provides a method, system, electronic device and storage medium for coordinated control of power supply arm switchgear based on an automatic matching algorithm.

[0051] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0052] The following is a detailed description of a specific scheme of a power supply arm switch device collaborative control method, system, electronic device and storage medium based on an automatic matching algorithm provided by the present invention in conjunction with the accompanying drawings.

[0053] See also Figure 1 and Figure 2 , which shows a method flow chart of a method for coordinated control of power supply arm switchgear based on an automatic matching algorithm provided by an embodiment of the present invention, the method comprising:

[0054] Step S100: configuring a preset operation sequence according to relevant data of the traction power supply system;

[0055] Step S100 specifically includes:

[0056] Step S110: Obtain the topological structure of the traction power supply system, extract the power supply arm number, the switchgear related to the power supply arm, and the power supply arm-related sites; specifically, perform a detailed analysis on each power supply arm in the traction power supply system, obtain the power supply range of the power supply arm, the connected power equipment (such as overhead line, traction transformer, etc.), and the position and function in the entire railway power supply network; secondly, for each power supply arm, obtain all the switchgear related to its power outage, including but not limited to circuit breakers, disconnectors, load switches, etc. For each switchgear, clarify its remote control operation command, such as closing, opening, etc.; it is also necessary to determine the traction substation and substation associated with the power supply arm;

[0057] Step S120: extracting the power-off and power-on operation sequence of the switch devices based on the electrical connection relationship between the switch devices; specifically, the remote control operation command of the switch covers all links from the start of the power-off or power-on operation to the completion of the operation, such as which switches to disconnect first during a power outage, and in what order to close the switches during power-on, etc. Then, according to the strict power-off and power-on execution sequence, the remote control operation commands of the switch devices corresponding to the power supply arm are respectively sorted into a power-on operation sequence and a power-off operation sequence. The power-off operation sequence is arranged by disconnecting the relevant switch devices in sequence from the load side to the power supply side; the power-on operation sequence is the opposite, and the switch devices are closed in sequence from the power supply side to the load side, so as to ensure that the power-off and power-on operations comply with electrical safety specifications and system operation requirements;

[0058] Step S130: configuring a preset operation sequence in combination with the operation type according to the power supply arm number, the power-off operation sequence, and the associated site; specifically, the preset operation sequence includes a preset power-off operation sequence and a preset power-on operation sequence. In the preset operation sequence, in addition to recording the remote control operation command of the switch device, the power supply arm number, the prerequisite for the power-off operation (such as the operating status of the adjacent power supply arm), the safety measures that may be required (such as the operation of the grounding switch), and the associated site are also required to be marked;

[0059] Step S200: Obtain the dispatch data of the target traction power supply system and extract the operation sequence related to the power supply arm; specifically, before the power outage operation at the skylight point begins, the system obtains the power supply arm related information involved in this operation from the dispatch database of the railway traction power supply system, including the power supply arm number, power supply range, connected switch equipment and associated sites; based on the obtained power supply arm information, the system automatically matches in the preset operation sequence, first determines the four basic information of the preset operation sequence, among which the step information is a clear definition of the specific operation steps and the order of sequence in each operation sequence, such as which switch to operate first and which one to operate later during the power outage operation. Detailed processes such as which switch to operate; the associated site information clarifies the site conditions associated with the power supply arm corresponding to the operation sequence, which is very important for judging the correlation between different power supply arms at the site level; the associated power supply arm information directly corresponds to the specific power supply arm number, so that the operation sequence is accurately linked to the specific power supply arm; the operation sequence type clearly marks whether it is a power outage or power supply operation; based on the above basic information, a matching rule is formulated, which requires that the power supply arm associated with the basic information in the operation sequence must be completely consistent with the power supply arm involved in the current skylight point, so as to ensure the pertinence of the operation and avoid mismatching with other power supply arms. At the same time, the operation sequence type must also be consistent with the actual operation (power outage or power supply) that needs to be performed on the power supply arm at the moment, so as to ensure the accuracy of the matching from the operation type. Only operation sequences that meet these two key conditions at the same time can be identified as valid operation sequences that match the current scene.

[0060] Step S200 specifically includes:

[0061] Step S210: extracting the skylight point time and the target power supply arm from the dispatching data of the target traction power supply system, connecting to the dispatching database of the target traction power supply system through a professional communication protocol and authorization mechanism, clearly storing the corresponding data table and field of the skylight point time and power supply arm information, using a database query statement, according to specific screening conditions, extracting the required skylight point time data from the corresponding data table, and screening the target power supply arm information according to conditions such as the power supply arm number, the region to which it belongs, etc., covering key contents such as the power supply arm number, the power supply range, and the connected switchgear;

[0062] Step S220: According to the number of the target power supply arm and the associated sites, extract the operation sequence that matches the target power supply arm from the preset operation sequence; specifically, in step S100, the preset operation sequence includes a preset power outage operation sequence and a preset power supply operation sequence, and according to the number of the target power supply arm and the associated sites, and according to the operation type of the target power supply arm, use data query to filter out the operation sequence that matches it.

[0063] Step S300: establishing a power supply arm association relationship based on the power supply arm related operation sequence, and generating an automated operation instruction set from a preset operation sequence;

[0064] Step S300 specifically includes:

[0065] Step S310: establishing a dependency relationship between operation sequences based on the electrical connection relationship between the power supply arms and the operation priority;

[0066] Step S310 specifically includes:

[0067] Step S311: extracting an electrical connection relationship diagram between power supply arms from the topological structure of the traction power supply system;

[0068] Step S312: extracting the operation sequence of the power supply arms according to the electrical connection relationship diagram; specifically, extracting the influence of the power outage and power supply operation sequence and the electrical interlocking situation according to the upstream and downstream relationship of the electrical connection of the power supply arms, and determining the operation sequence constraints between the power supply arms;

[0069] Step S313: Define the dependency type and construct a dependency graph based on the mutual influence relationship between the power supply arms, including pre-dependency and parallel dependency; specifically: compare the associated sites of the related operation sequences of every two power supply arms, mark the power supply arms with the same associated sites as potential dependencies, and mark the power supply arms with different associated sites as potential parallel relationships; extract the influence of the power outage and power supply operation sequence and the electrical interlocking status based on the upstream and downstream relationships of the electrical connections of the power supply arms, and determine the operation sequence constraints between the power supply arms; mark the sites with station associations and operation sequence constraints as pre-dependencies, and those without operation sequence constraints as parallel Dependency relationship; taking the power supply arm as the node, draw the directed edge from the dependent power supply arm to the dependent power supply arm according to the predecessor dependency relationship, and draw the undirected edge according to the parallel dependency relationship; specifically, during the power outage operation, sort out the precedence relationship between the power supply arms in the order from the load side to the power supply side. For example, if the power supply arm M is on the load side and is in the downstream position in the electrical connection with the power supply arm N, then for the power outage operation, the power outage operation of the power supply arm M should be performed before the power supply arm N, and it is marked that the power supply arm N has a predecessor dependency on the power supply arm M, that is, the power outage operation of the power supply arm N depends on the power supply arm M to complete the power outage first. The power transmission operation is the opposite, and the order is determined from the power supply side to the load side. For power supply arms with electrical interlocking, for example, the power transmission of a power supply arm requires the specific switch state of another power supply arm as an interlocking condition, it is also determined that there is a pre-dependency relationship, and the order constraints on the operation sequence are clarified. Then, those with station association and operation sequence constraints are marked as pre-dependencies, and those without operation sequence constraints are marked as parallel dependencies. If there is both station association between power supply arms that cannot be executed in parallel and operation sequence constraints on electrical connections (such as pre-dependencies), they are clearly marked as pre-dependencies and their order requirements are recorded. For example, the power supply arms under the same traction substation and with a clear order of power outages on electrical connections are pre-dependencies. If the power supply arms are determined to have the conditions for parallel execution after station association and electrical connection analysis, and there are no restrictions on the operation sequence, they are marked as parallel dependencies, indicating that they can be operated simultaneously. Finally, with the power supply arm as the node, a directed edge pointing from the dependent power supply arm to the dependent power supply arm is drawn according to the pre-dependency relationship, and an undirected edge is drawn according to the parallel dependency relationship. With the power supply arm as the node, a directed edge (for pre-dependency) or an undirected edge (for parallel dependency) is drawn according to the marked dependency type to construct a dependency graph; for example, if the power supply arm X has a pre-dependency on the power supply arm Y, an arrow is drawn from the X node to the Y node in the graph to indicate the direction of this dependency; for parallel dependencies, undirected edges are drawn between the corresponding power supply arm nodes to indicate that they can operate in parallel. For example, between the power supply arms Z and W marked as parallel dependencies, a line segment is used to connect the Z and W nodes.

[0070] Through the above steps, the dependency type can be defined according to the mutual influence relationship between the power supply arms, and a dependency graph including pre-dependencies and parallel dependencies can be constructed, providing a clear relationship basis for subsequent topological sorting and generation of automated operation instruction sets.

[0071] Step S314: topologically sort the dependency graph to generate a linear automated operation instruction set; specifically, for the constructed dependency graph, a topological sorting algorithm can be used to sort the operation sequences corresponding to each power supply arm according to the pointing order of the edges in the dependency graph, and the operation sequences with sequential dependencies are arranged in sequence, and unreasonable situations such as circular dependencies are removed, thereby generating a linear automated operation instruction set to ensure that the execution order of the operation sequence conforms to the dependency relationship between the power supply arms;

[0072] Step S320: Generate and control an automated operation instruction set according to the dependency relationship between the operation sequences;

[0073] Step S320 specifically includes:

[0074] Step S321: Assign operation sequences without dependencies to different parallel control automation operation instruction sets; specifically, first initialize the parallel control automation operation instruction set container, that is, create a set of empty parallel control automation operation instruction sets, each instruction set as an independent execution unit, used to store operation sequences that conform to specific relationships. Then, traverse all operation sequences and the corresponding dependency graphs, and check the connection status of each operation sequence in the graph. For those operation sequences that have no dependencies with all other operation sequences (the corresponding nodes in the dependency graph have no connecting edges with other nodes), create a new parallel control automation operation instruction set for it separately, and put the operation sequence into it. This ensures that operation sequences without dependencies can be executed in parallel without interfering with each other, making full use of system resources and improving overall execution efficiency;

[0075] Step S322: assign the same parallel control automation operation instruction set to the operation sequences with dependencies; specifically, when encountering an operation sequence with dependencies (connected by edges in the dependency graph), trace the dependency chain along the directed edges (for the predecessor dependencies) through a depth-first search or breadth-first search algorithm to find all the operation sequences with dependencies, and then assign all these operation sequences with dependencies to the same parallel control automation operation instruction set, and arrange the order of the operation sequences in this instruction set according to the direction of the edges in the dependency graph to ensure that the predecessor-dependent operation sequences are placed in front, so that the operation sequence constraints are strictly followed during the execution process to ensure the orderliness and accuracy of the coordinated control operation of the entire power supply arm switch equipment;

[0076] Specifically, for example Figure 2Taking the eight power supply arms A, B, C, D, E, F, G, and H as an example, according to the preset operation sequence rules, each power supply arm has a corresponding power outage and power transmission operation sequence and is associated with the power supply arm information and site information; by analyzing the site information associated with the operation sequence of each power supply arm, the operation sequences of power supply arms A, B, C, and D are associated with the same site (traction substation A), so they cannot be executed in parallel; the operation sequences of power supply arms E, F, G, and H are associated with the same site (traction substation B), so they cannot be executed in parallel; and combinations such as AE, AF, AG, and AH can be executed in parallel because the operation sequences involved are associated with different sites; the specific example scenario is: if the skylight point power outage involves power supply arms A, B, G, and H, the corresponding reasonable parallel control queue can be generated according to the above principle, and the execution order and parallel relationship can be arranged in actual operation; for example, the first parallel control queue is to execute the operation sequence of power supply arms A and B in sequence, and the second parallel control queue is to execute the operation sequence of power supply arms G and H in sequence.

[0077] Step S400: execute the power-off steps in sequence according to the automated operation instruction set and feedback the execution results; specifically, after receiving an execution command for a certain operation sequence, execute the corresponding specific operation steps in sequence according to the execution sequence of the configuration steps in the operation sequence, such as operating the corresponding switch equipment, etc., and after completing each step, feedback the execution result to the parallel control execution sequence module at the previous level; through such a layer-by-layer feedback and strict step-by-step execution mechanism, it is guaranteed that the entire parallel control execution process can accurately and orderly realize the power-off operation of the power supply arm, and at the same time facilitate the monitoring and management of the operation status of each link.

[0078] To sum up, the power supply arm switch equipment collaborative control method based on the automatic matching algorithm provided by the present invention automatically matches the corresponding operation sequence and automatically executes the parallel control operation sequence, which effectively avoids power outage errors caused by human operation errors, reduces the workload of electric dispatchers and allows them to focus on problem analysis and fault handling, and utilizes the characteristic that the parallel control execution sequence can be executed in parallel. Different parallel control execution sequences can be executed simultaneously without interfering with each other, thereby reducing the time consumption of power outage and improving the utilization rate of skylight points, thereby improving the overall efficiency of the power outage operation of the power supply arm switch equipment in the traction power supply system and the convenience of management, effectively avoiding erroneous operations caused by human factors, and ensuring the safe and stable operation of the power supply system.
