In the specific implementation, after the server obtains the fault node information and the emergency repair resource information, the server generates a flow directed graph of each idle emergency repair resource corresponding to the fault node according to the fault node information and the emergency repair resource information.
Wherein, the flow directed graph comprises at least one first-aid repair operation path; each first-aid repair operation path is used for representing the first-aid repair operation flow of the idle first-aid repair resources; the rush-repair work path has a corresponding total work time.
And step S230, respectively determining the first-aid repair operation path with the maximum total operation consumption time in each flow directed graph to obtain the key operation path corresponding to each idle first-aid repair resource.
In the specific implementation, the server determines the first-aid repair operation path with the largest total operation consumption in each flow digraph respectively to obtain the key operation path corresponding to each idle first-aid repair resource.
Step S240, distributing corresponding target emergency repair resources for the fault node based on the total operation time consumption of the key operation path corresponding to each idle emergency repair resource; the total operation time consumption of the key operation path corresponding to the target emergency repair resource is less than that of the key operation path corresponding to other emergency repair resources; and the other emergency repair resources are emergency repair resources except the target emergency repair resource in each idle emergency repair resource.
In the specific implementation, the server allocates corresponding target emergency repair resources to the fault node based on the total operation time consumption of the key operation path corresponding to each idle emergency repair resource; the total operation time consumption of the key operation path corresponding to the target emergency repair resource is less than that of the key operation path corresponding to other emergency repair resources; and the other emergency repair resources are emergency repair resources except the target emergency repair resource in each idle emergency repair resource.
For example, the server numbers all failed nodes in order of importance. Then, the server makes a flow directed graph Gij corresponding to the fault node by each team aiming at the fault node with the highest importance degree in the fault node queue, then, the server traverses each flow directed graph Gij, finds out a target emergency repair resource corresponding to the fault node, namely the team corresponding to minGij, and outputs a corresponding distribution result. And then, the server continues to allocate corresponding target emergency repair resources to the fault node with the second importance degree in the fault node queue according to the mode until all the node allocation is completed and the emergency repair work is finished.
In the distribution method of the power distribution network post-disaster emergency repair resources, the information of the fault node including the node state and the node position of the fault node, and the information of the emergency repair resources including the moving speed, the position and the emergency repair time consumption of at least one idle emergency repair resource are obtained; generating a flow directed graph of each idle emergency repair resource corresponding to the fault node according to the fault node information and the emergency repair resource information; the flow directed graph comprises at least one first-aid repair operation path; each first-aid repair operation path is used for representing the first-aid repair operation flow of the idle first-aid repair resources; the rush-repair operation path has corresponding operation total time consumption; determining the first-aid repair operation path with the largest total operation consumption time in each flow digraph respectively to obtain a key operation path corresponding to each idle first-aid repair resource; finally, distributing corresponding target emergency repair resources for the fault node based on the total operation time consumption of the key operation path corresponding to each idle emergency repair resource; the total operation time consumption of the key operation path corresponding to the target emergency repair resource is less than that of the key operation path corresponding to other emergency repair resources; therefore, the position relation between the emergency repair resources and the fault node can be fully considered when the corresponding emergency repair resources are distributed for the fault node, so that the emergency repair resources which are in a busy state and are close to the fault node are also distributed at a follow-up opportunity, the time consumed when the target emergency repair resources move to the fault node is reduced, the time length of emergency repair work is further shortened to a certain extent, the emergency repair work efficiency is improved, and the disaster damage is reduced.
In another embodiment, if there are multiple failed nodes, allocating corresponding target emergency repair resources to the failed node based on the total time consumption of the jobs of the critical job path corresponding to each idle emergency repair resource, including: acquiring the importance degree of each fault node; based on the importance degree, sequencing all fault nodes to obtain a fault node queue; and on the basis of the total operation time consumption of the key operation path corresponding to each idle first-aid repair team, sequentially distributing corresponding target first-aid repair resources for each fault node in the fault node queue until each fault node has the corresponding target first-aid repair resources.
In the specific implementation, if a plurality of fault nodes are provided, the server can acquire the importance degree of each fault node in the process of allocating corresponding target emergency repair resources to the fault node based on the total operation time of the key operation path corresponding to each idle emergency repair resource; then, the server can sort the fault nodes in the order from high to low based on the importance degree to obtain a fault node queue; and then, the server sequentially allocates corresponding target emergency repair resources to each fault node in the fault node queue based on the total operation time consumption of the key operation path corresponding to each idle emergency repair team until each fault node has the corresponding target emergency repair resources.
To facilitate understanding by those skilled in the art, fig. 3 provides a flow chart of emergency repair resource allocation; wherein, as shown in fig. 3, at the beginning of the emergency repair work, the server obtains the node state C of the failed nodeiAnd node position, and, moving speed v of idle repair resourcesiAnd position posiAnd so on. Then, the server numbers all the failed nodes in order of importance. Then, the server makes a flow directed graph G of each queue corresponding to the fault node aiming at the fault node with the highest importance degree in the fault node queueijThen, the server traverses each flow directed graph Gij, finds out the target emergency repair resource corresponding to the fault node, namely the team corresponding to minGij, and outputs the corresponding distribution result. And then, the server continues to allocate corresponding target emergency repair resources to the fault node with the second importance degree in the fault node queue according to the mode until all the node allocation is completed and the emergency repair work is finished.
According to the technical scheme of the embodiment, the importance degree of each fault node is obtained; based on the importance degree, sequencing all fault nodes to obtain a fault node queue; based on the total operation time consumption of the key operation paths corresponding to the idle first-aid repair teams, corresponding target first-aid repair resources are sequentially allocated to each fault node in the fault node queue until each fault node has the corresponding target first-aid repair resources, and therefore the idle first-aid repair resources are sequentially allocated to each fault node in the fault node queue according to the importance degree of each fault node.
In another embodiment, sorting the fault nodes based on the importance degree to obtain a fault node queue, including: numbering each fault node according to the sequence of the importance degree from high to low; and determining a fault node queue based on the number of each fault node.
In the specific implementation, the server can number each fault node according to the order of the importance degrees from high to low in the process of sequencing each fault node based on the importance degrees to obtain a fault node queue; then, the server creates a fault node queue based on the number of each fault node.
According to the technical scheme of the embodiment, each fault node is numbered according to the order of importance degree from high to low, and the fault node queue is determined based on the number of each fault node, so that the server can conveniently and sequentially allocate idle first-aid repair resources to each fault node in the fault node queue in the follow-up process.
In another embodiment, according to the failure node information and the first-aid repair resource information, generating a flow directed graph of the failure node corresponding to each idle first-aid repair resource, including: calculating the time consumed by moving the idle first-aid repair resource to the fault node based on the node position, the moving speed of the idle first-aid repair resource and the position of the idle first-aid repair resource; acquiring the rush-repair time consumption of the idle rush-repair resources, and generating a flow digraph of each idle rush-repair resource corresponding to a fault node based on the rush-repair time consumption, the mobile time consumption and the node state of the fault node.
Wherein, based on the node state of rush-repair consuming time, moving consuming time and fault node, generating a flow directed graph of each idle rush-repair resource corresponding to the fault node, including: determining an emergency repair work flow of idle emergency repair resources in a fault node according to the node state of the fault node; and generating a flow digraph of the fault node corresponding to each idle emergency repair resource according to the emergency repair work flow, the emergency repair time consumption and the moving time consumption.
In the specific implementation, in the process that the server generates the flow digraph of the fault node corresponding to each idle first-aid repair resource according to the fault node information and the first-aid repair resource information, the server can calculate the time consumed by moving the idle first-aid repair resource to the fault node based on the node position, the moving speed of the idle first-aid repair resource and the position of the idle first-aid repair resource; then, the server obtains the rush-repair time consumption of the idle rush-repair resources, and finally, the server determines the rush-repair work flow of the idle rush-repair resources in the fault node according to the node state of the fault node; and generating a flow digraph of the fault node corresponding to each idle emergency repair resource according to the emergency repair work flow, the emergency repair time consumption and the moving time consumption.
In view of the distribution network emergency repair management standard issued by a certain power company, a complete distribution network post-disaster repair can involve a large number of departments, wherein the main departments and the functions thereof are shown in table 1.
TABLE 1
As can be seen from the above table, in the first-aid repair work, there are quite a lot of departments involved, and therefore, a complicated process is necessary. The complex flow becomes the biggest barrier for preventing the high-efficiency first-aid repair work of the power distribution network after the disaster. According to the relevant regulations, one complete first-aid repair work is carried out through the following processes,
1. and (3) fault repair acceptance: after the repair hot line telephone sub-center of the marketing service operation and management center accepts the customer fault repair appeal, the fault condition is inquired in detail and the customer service quick response center is issued to perform response processing.
2. And (4) order receiving and dividing: after the relevant city bureau quick-response center receives the fault repair work order, the order receiving and dividing management or the order returning should be finished within three minutes respectively.
3. And (3) fault notification: and the emergency maintenance team receives the emergency maintenance instruction of the quick response center and acquires the fault occurrence information.
4. And (3) fault finding: the emergency maintenance team arrives at the site and reports arrival time, the fault is judged after the fault point is found, the fault reason, the power failure range, the power failure area and the predicted recovery time are reported to the quick response center personnel, and the quick response center personnel are responsible for timely inputting fault related information into the system.
5. Fault isolation: after the emergency repair personnel find out the cause of the fault, the fault should be isolated as soon as possible. The device belongs to equipment managed by dispatching, and a person on duty needs to be dispatched to issue a command, so that emergency repair personnel can perform switching operation and isolate faults.
6. And (4) permission work: the emergency maintenance team should fulfill the approval process according to the relevant regulations.
7. On-site first-aid repair: the emergency maintenance team handles the failure according to the relevant regulations. The simple fault is directly processed by first-aid repair first fleets; and the large-scale fault emergency repair of the distribution network is processed by informing the emergency repair second fleet by distribution network emergency repair commanders.
8. Reporting the result: after the fault is processed, rush repair personnel report to the quick response center, and the quick response center recovers to timely record information such as fault recovery power transmission time into the system.
9. And (3) power transmission recovery: for the equipment managed by the dispatching department, the dispatching is needed to issue an instruction, and the emergency repair personnel can recover the power transmission operation.
The above process can be represented by using a directed graph, and the obtained directed graph is shown in fig. 4.
Optimized point specified by actual power distribution network emergency repair work flow
According to the above department functions and the regulations of the process, it can be seen that the following points are very obvious and can be optimized in the process:
1. the number of departments involved in the process is extremely large, and although each work process is subjected to response time limitation, the number of work involved in the whole first-aid repair process is extremely large, so that the time delay between each step is long, and the work efficiency is reduced.
2. The whole fault flow lacks dynamic allocation and dynamic regulation, so that the distribution of workers is not flexible, and the phenomenon that some regions are lack of personnel, but other regions have idle personnel, can occur.
3. In the fault flow, only the first echelon and the second echelon of maintenance personnel are considered, no further optimization scheme is provided, so that a backup scheme for fault maintenance is insufficient, the capability of coping with emergency is poor, and personnel allocation problems can occur when coping with serious disasters.
Aiming at the optimizable points, the whole emergency repair process can be subjected to mathematical abstraction, the whole process is abstracted into a directed graph G, and each work is set as a uniform node piThe delay time required between every two jobs is set to ti. Wherein, tiAnd various parameters in the emergency repair work. An abstracted directed graph G is shown in fig. 5. Wherein the delay time t in FIG. 5iThe specific meanings of (A) are shown in the following Table 2,
TABLE 2
According to the above with respect to tiDefinition of (2), it can be found thatiThe calculation can be carried out by specific parameters in the emergency repair work, and expressions of ti and the parameters can be obtained as shown in table 2 (wherein the expression that Ci represents the time is not or less influenced by the outside, and is only influenced by the emergency repair sheetA constant controlled by the bit itself).
TABLE 3
As can be seen from the table, most of the delay times in the table are constant, and are specific values determined according to the unit specification and the specification, and the variable space is relatively small. The parameter which is mainly variable is t5And t10Namely, the time spent by the emergency repair team on the road and the actual repair time of the emergency repair team are variable, and the parameters become the key for optimizing the whole emergency repair process and are main optimization parameters. These two parameters will be mentioned repeatedly in the discussion that follows.
According to the technical scheme, the position relation between the emergency repair resources and the fault node can be fully considered when the corresponding emergency repair resources are distributed for the fault node, so that the emergency repair resources which are in a busy state and are close to the fault node are also distributed at a later stage, the time consumed when the target emergency repair resources move to the fault node is reduced, the time length of emergency repair work is further shortened to a certain extent, the emergency repair work efficiency is improved, and the disaster loss is reduced.
In another embodiment, the step of allocating corresponding target emergency repair resources to the failed node after the step of allocating corresponding target emergency repair resources to the failed node based on the total operation time of the critical operation path corresponding to each idle emergency repair resource includes: generating a fault node first-aid repair instruction according to the node state of the fault node and the node position of the fault node; and sending a fault node emergency repair instruction to a target emergency repair team corresponding to the fault node so as to indicate the target emergency repair team to go to the node position to carry out emergency repair operation on the fault node.
In the concrete implementation, the idle emergency repair resources are idle emergency repair teams, the server allocates corresponding target emergency repair resources for the fault node based on the total operation time of the key operation path corresponding to each idle emergency repair resource, and then the server can generate a fault node emergency repair instruction according to the node state of the fault node and the node position of the fault node. Then, the server can send the emergency repair instruction of the fault node to a target emergency repair team corresponding to the fault node so as to instruct the target emergency repair team to go to the node position to perform emergency repair operation on the fault node.
To facilitate understanding by those skilled in the art, fig. 6 also provides a rush-repair flow chart of a target rush-repair team; after receiving a fault node emergency repair instruction, a target emergency repair team marks the target emergency repair team as a busy emergency repair team by the server, meanwhile, the target emergency repair team goes to the fault node (for example, the ith node) to perform emergency repair on the ith node, and after the target emergency repair team finishes the emergency repair on the fault node, the target emergency repair team determines whether the instruction of the next fault node is received or not; and if the target rush-repair team receives the instruction of rush-repairing the next fault node, the target rush-repair team carries out rush-repair on the next fault node in front. And if the target emergency repair team does not receive the instruction of emergency repair of the next fault node, the target emergency repair team performs a standby state until receiving the command of continuing the emergency repair.
According to the technical scheme, the fault node rush-repair instruction is generated to the target rush-repair team by sending the node state based on the fault node and the node position of the fault node, and the aim of indicating the target rush-repair team to go to the node position in time to carry out rush-repair operation on the fault node is achieved.
