Example 2:
in this embodiment, the theoretical line loss management method in embodiment 1 is implemented and verified by using eastern electric power company of mongolia in the national grid as an example, and specifically includes the following steps:
the theoretical line loss management work covers all voltage levels of 500kV, 220kV, 110kV, 66kV, 35kV, 10kV, 380V and the like of eastern electric power limited company (hereinafter referred to as Mongolian company) of Mongolia in China, is led by the administration department, is organized and implemented by Mongolian electric academy (hereinafter referred to as electric academy), and comprises work contents such as software platform maintenance, technical support, actual measurement of daily representative load, data entry, work content summary report analysis and the like.
As an important supporting unit, the electric academy undertakes the work of theoretical calculation and analysis of main line loss of 220kV and above, and simultaneously takes charge of the management work of theoretical line loss of each voltage class, so that the electric academy needs to be connected with each professional department of city companies and county companies and also needs to provide technical support for each voltage class project group, and the electric academy is under the main pressure from the aspects of wide service coverage, large workload, heavy task, low communication efficiency and the like.
In the traditional management mode, as shown in fig. 1, each unit and department is directly connected with the electric academy in addition to the upper and lower management mechanisms, the management mode has complex structure and large information flow, and has the problems of redundant information, multiple repetitive support work, low efficiency and the like, and management innovation is urgently needed to adapt to the new theoretical line loss management work situation. Based on the method, the electric academy is innovated and applied to a theoretical line loss management system based on the hub and spoke model, information resources can be effectively integrated, information redundancy is reduced, repetitive work is reduced, work efficiency is improved, complex management work of theoretical line loss is effectively solved, and efficient completion of a task of successfully assisting theoretical line loss management is successfully completed.
As shown in fig. 2, the hub and spoke theory is a model proposed by Morton E.O' kelly, state university, ohio, for site selection and network design of network hub facilities, originally used in the air transportation route planning of research america; with the continuous and deep research of the spoke-axis theory, the theory has been applied to many fields such as regional development strategy, business trade and the like; the structure of the wheel consists of a shaft and spokes, and is a space form similar to a wheel; the axis refers to a hub in the network and is responsible for transferring and distributing most of resources in the whole network; the spokes are the routes between the hub to each end node.
Monte electric academy refers to the management mode, and introduces an axis node (electric academy management axis) on the basis, and applies the axis node to theoretical line loss management work, thereby driving the efficient flow of information flow, data flow and service network flow, and playing the roles of optimizing a management system and reducing the total management cost.
As shown in fig. 3, the area of the district of the monndon company is large, 4 prefectural companies are administered, 41 flag-county companies are counted, the service covers all voltage levels of 400V-500 kV, and the theoretical line loss management work relates to many departments from top to bottom, including departments of planning, scheduling, electric academy (project group), scheduling of four prefecture companies, overhauling of each flag county, marketing and the like. According to the hub-spoke theory, Mongolian electric academy is selected as the axis, companies in Chifeng, Tongliao, Xingan and Relunbel Sidi city are selected as hub nodes, and power supply stations and teams and groups governed by various flag county units are selected as non-hub nodes. The axle center node information is directly fed back to a company planning and scheduling department, the management demand information is released to a hub node (four cities) in a radiation mode, and the hub node flows to a linked non-hub node to form the shunting of axle center management work to a terminal node.
The dotted line part represents a data platform used by each unit node in the transverse direction, data flow is formed in the longitudinal direction, the axis points to the terminal node as the information issuing direction to form information flow, and the terminal node points to the axis as the service summarizing direction to form service flow.
Aiming at the minimum total management cost Z, the management cost of the axial electric department to the city is set as A, and A is set asElectric academy → prefecture iRepresents the management cost of the electric academy of sciences to the city of land i, AElectric academy → flag county ijThe cost of managing or technically supporting the prefecture j of the prefecture i by the electric academy of sciences is represented by AElectric academy → electric power station/team ijkThe cost of managing or technically supporting a team k belonging to a flag county j belonging to a prefecture i by the electric academy of sciences, the management cost of the flag county of the prefecture is B, and B is usedPrefecture i → Qin county ijThe management cost of the local city i directly to the flag county ij in the district is shown, the management cost of the flag county to the power supply station/team is C, and C is usedFlag county ij → power supply station/team ijkThe management cost of flag county ij directly to the power supply station/team ijk under the jurisdiction of flag county ij is represented, and the minimum total management cost Z is taken as a target function, so that the following relationship is satisfied:
wherein:the generation of training for electric department to the city of the hub nodeThen, the process is carried out;
the above formula can be processed to obtain:
(Aelectric academy → prefecture i+BPrefecture i → Qin county ij+CFlag county ij → power supply station/team ijk)<(AElectric academy → prefecture i+AElectric academy → flag county ij+CElectric academy → electric power station/team ijk)。
Compared with the cost brought by the fact that the electric academy needs to directly manage or technically support each department participating in line loss management in the traditional mode, the hub and spoke type management mode can obviously reduce the management cost, and the cost required by training the electric academy on the hub node city i needs to be pointed outThe value of the management system is constant, and the management system only needs a single training to enable companies in various cities to adapt to a hub and spoke type management mode, so that the management system belongs to one-time cost, and the hub and spoke type management mode emphasizes the enhancement of the service capability of the hub node, so that the cost is not included in the subsequent management years.
It should be noted that, in the previous mode of performing management according to voltage class, the management cost required by the electric academy for directly managing data of different voltage classes in the jurisdiction is equivalent to the management cost required by the electric academy for directly managing or technically supporting the voltage class responsible unit, and as can be found by comparing fig. 1 and fig. 3, the management branch of the latter is reduced by 50% compared with the former, so that the hub and spoke type management mode can simplify the management process and effectively reduce the management cost while improving the management efficiency.
In the theoretical line loss management work, the process of summarizing results by different voltage level management departments is a refining process of information clusters which are mutually connected and interacted. Practice shows that under the constraint of timeliness and accuracy, each management department (node) on the hub-and-spoke branch can actively adapt to the management mode according to the self condition, further define self positioning, quickly improve the refinement and specialization level of the self service by taking the basic service of the branch as a work key point, form a good service distribution relation with upstream and downstream nodes, enhance the service level of the branch below the hub node, enhance the management capability of the hub node by the axis, finally make the management vein clear, and form a reasonable management structure of 'axis radiation and branch centripetal'.
For theoretical line loss management, the hub and spoke management system is a network management structure formed by the combined action of a hub node and a city hub node. Isolated management nodes are connected to provide a hub management connection point, distributed management nodes (flag county, power supply station and team group) are brought into a network, so that the network nodes are more reasonably connected, the flow of management information is more efficient, the one-time distribution of the axis node of a service to the hub node is realized, the one-to-one management of the hub node to a non-hub node is realized, one-to-many management branches of an axis management department (electric academy) are omitted, the management flow is simplified, and the joint action of the axis node and the hub node is more efficient than the centralized assignment of management tasks to each node by the axis node. Due to the fact that the management branch is 'slim', management costs of time, manpower and the like caused by communication congestion are correspondingly reduced.
From the view of the regional management range, the establishment of the hub node gets rid of the geographical position limitation, the rapid 'digestion and absorption' of information is facilitated, the single information flow and the task release are more accurate and timely, and the time cost is greatly saved, so that the hub and spoke type management system is particularly suitable for Mongolian companies with large scope of jurisdiction, multiple voltage levels, wide distribution of transformer stations and multiple line loss management work participation departments.
The national grid Monte electric academy adopts a radial organization management structure in 2019 theoretical line loss management, and the following remarkable effects are achieved:
firstly, theoretical line loss management work efficiency is improved, compared with a traditional management mode, a hub and spoke type management mode is adopted to realize one-time distribution of service axis nodes to hub nodes, management procedures are greatly simplified, repeated work is avoided, and management implementation efficiency is obviously improved. Fig. 4 shows the number of links in which the line loss theoretical calculation work information is transmitted in 2018 and 2019.
As can be seen from fig. 4, the average history link of the theoretical calculation of the line loss in 2018 is 24, the spoke type management model is adopted in 2019, the average history link is shortened to 12, and the application of the spoke type organization structure greatly simplifies the management process and effectively improves the working efficiency.
Secondly, the efficient utilization of human resources is realized, and the hub-and-spoke type management system is a network management structure formed by the combined action of the overall management (electric academy) and the regional management (city hub), so that the total output of management results is enlarged, and the efficient utilization of the human resources is realized. Table 1 shows statistics of line loss theoretical calculation work participants and task completion conditions of the national grid monndon company in 2018 and 2019.
TABLE 1 line loss theoretical calculation of participants and completion statistics
As can be seen from table 1, the number of participants in the line loss theoretical calculation in 2019 is reduced by 31.09% compared with that in 2018, the task completion amount is increased by 33.65%, which indicates that efficient utilization of human resources can be realized by using a hub and spoke type organization structure for management.
Thirdly, the overall quality of theoretical line loss management is enhanced, management departments on the hub-and-spoke type branches concentrate strength to develop basic service of the branches on which the management departments are located according to self conditions, the service level is enhanced, and the accuracy and the specialty of task execution are guaranteed. With the full score of each index of 10 as a standard, fig. 5 shows the comparison condition of the completion quality of the line loss theoretical calculation in 2018 and 2019 in the aspects of data accuracy, report speciality and conclusion reliability.
As can be seen from fig. 5, in 2019, by using the hub and spoke type management mode, the data accuracy, the report specialty, and the conclusion reliability are all significantly improved, which indicates that the mode effectively enhances the overall quality of theoretical line loss management.
