Description

Technical Field

[0001] The present invention belongs to the technical field of reducing power outages in power distribution network lines, and specifically relates to a power distribution network line fault query and early warning system based on the OMS platform. Background Art

[0002] With the continuous improvement of the high-quality service requirements within the State Grid system, for the power dispatching center, high-quality service means no power outages, or minimizing power outage time, or having different response plans for the number of power outages of different lines, and when a certain line fails or there is a power outage requirement, accurate data of that line can be provided as soon as possible.

[0003] Currently, planned power outages, fault power outages, and emergency repair power outages are not in the same system. Planned power outages are in the OMS system, fault power outages are in the form of offline Excel spreadsheets, and emergency repair power outages are in the dispatching log. If you need to understand the overall power outage situation, you need to export and summarize the above three items from different systems for analysis. The data volume is large during annual statistics, wasting a lot of manpower and material resources, and the work is inconvenient and inefficient. To solve the above problems, it is necessary to develop a power distribution network line fault query and early warning system based on the OMS platform. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a power distribution network line fault query and early warning system based on the OMS platform with high work efficiency and more reasonable power outage plan arrangements, which can effectively improve the power supply reliability of the power distribution network.

[0005] The purpose of the present invention is achieved as follows: A power distribution network line fault query and early warning system based on the OMS platform, including the OMS platform, characterized in that: it further includes

[0006] A database module for storing relevant data of planned power outages, fault power outages, and emergency repair power outages, including occurrence time, line name, voltage level, affiliated substation, power outage type, and power outage reason;

[0007] A security authentication module for providing security guarantee for accessing the database module;

[0008] A fault query module for querying the fault statistics of the same line according to the query needs, and the specific query situation is as follows:

[0009] Line Name Voltage Level Substation to Which It Belongs Power Outage Type Power Outage Reason Number of Recent Power Outages

[0010] A fault warning module, which is used to determine whether to conduct a power outage color warning for the queried line according to the fault query result and conduct a power outage color warning according to preset requirements, and automatically display it to the query result when there is a power outage color warning. Specifically, when the number of power outages within 60 days is once, it is marked yellow, and when it is two or more times, it is marked red.

[0011] A planned maintenance module, which is used to automatically generate a power outage maintenance plan according to the fault query result and automatically send it to the relevant responsible person when there is a power outage color warning. Specifically, when there is a yellow warning, a power outage warning plan is generated, and when there is a red warning, a power outage maintenance plan is generated.

[0012] A plan approval module, which is used for the relevant responsible person to quickly complete the approval work of the power outage maintenance plan by directly viewing the fault query result.

[0013] A man-machine interaction module, including a user interface located at the WWW browser end and a management interface located at the server end.

[0014] Preferably, when the power outage type is planned power outage, the reason for the power outage is filled with the work task; when the power outage type is fault power outage, the reason for the power outage is filled with the action situation, the disconnection position and the fault point; when the power outage type is emergency repair power outage, the reason for the power outage is filled with the disconnection switch position and the emergency repair content.

[0015] Preferably, according to the query needs, through the user interface, the recent power outage times of the same line within different time ranges can be queried, including the total power outage times, planned power outage times, fault power outage times and emergency repair power outage times.

[0016] Preferably, the different time ranges are one day, one month, two months, six months or one year.

[0017] Preferably, the fault query work can be triggered actively by humans or automatically by the system according to preset requirements.

[0019] Preferably, the database module uses an Oracle relational database to conduct integrated management of data from different sources.

[0020] Due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows: On the basis of the existing OMS platform, by integrating a database module, a security authentication module, a fault query module, a fault warning module, a planned maintenance module, a planned approval module, and a human-computer interaction module, it is convenient for each department to quickly obtain the recent power outage times and outage reasons of planned power outages, fault power outages, and emergency repair power outages on the same page of the OMS system. At the same time, when the recent power outage of a line exceeds a certain range, it will automatically send a warning in a text message, and when conducting planned approval, this system can be directly used as a basis. If it is found that the number of trips exceeds 2 times within 60 days, it can be directly marked, avoiding frequent and repeated planned power outages of the line, facilitating each department to promptly initiate relevant work, reasonably arrange the line power outage plan, and effectively improve the quality service level of the power grid; Generally, the present invention has the advantages of high work efficiency and more reasonable power outage plan arrangement, effectively improving the power supply reliability of the distribution network, and having positive social and economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 It is the system working flowchart of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solution of the present invention will be further specifically described below through embodiments and in combination with the drawings.

[0023] As Figure 1 shown, the present invention provides a distribution network line fault query and warning system based on the OMS platform, including the OMS platform and its database module, security authentication module, fault query module, fault warning module, planned maintenance module, planned approval module, and human-computer interaction module.

[0024] Among them, the OMS platform is the full name of the State Grid Intelligent Dispatching Management System (Outage Management System), which is the core platform of the State Grid Corporation for power system dispatching management. It mainly has core functions such as planned power outage management, fault power outage management, real-time data monitoring, and customer service support. By integrating data in each link of the power grid, it realizes intelligent dispatching and operation and maintenance management, and is the key technical support platform for improving power supply reliability and service level. The present invention is based on the existing OMS platform and adds the following modules to enhance the fault power outage management function of the OMS platform.

[0025] Among them, the database module is used to store relevant data of planned power outages, fault power outages, and emergency repair power outages, including occurrence time, line name, voltage level, affiliated substation, power outage type, and power outage reason.

[0026] Specifically, the database module uses an Oracle relational database to perform fusion management on data from different sources. The Oracle relational database management system has a large storage capacity, is easy to use, has high security, strong readability, and its encryption management meets the growing demand for stronger security of information in the data center. The program code is independent of the database, facilitating data transplantation and program maintenance.

[0027] Among them, the security authentication module is used to provide security guarantees for accessing the database module.

[0028] Among them, the fault query module is used to query the fault statistics of the same line according to the query requirements.

[0029] Taking the 10 kV distribution network line as an example, the power outage types are divided into three categories: planned power outage, fault power outage, and emergency repair power outage. After integrating the three types of power outages into the database, the historical fault conditions of each line can be specifically queried according to the following table for later analysis and decision-making:

[0030] Line Name Voltage Level Substation to Which It Belongs Power Outage Type Power Outage Reason Number of Recent Power Outages

[0031] Specifically, when the power outage type is a planned power outage, the reason for the power outage is filled with the work task; when the power outage type is a fault power outage, the reason for the power outage is filled with the action situation, disconnection location, and fault point; when the power outage type is an emergency repair power outage, the reason for the power outage is filled with the disconnection switch location and the emergency repair content.

[0032] Among them, the planned power outage is directly synchronized from the OMS planned maintenance management module, and the lines with the daily plan already executed are synchronized to this module. The fault power outage and the emergency repair power outage are manually entered into this module by the dispatcher, and after entry, this module automatically synchronizes to the dispatching log.

[0033] Among them, the fault warning module is used to judge whether to conduct a power outage color warning for the queried line according to the fault query result and conduct a power outage color warning according to the preset requirements, and automatically display it to the query result when there is a power outage color warning.

[0034] Specifically, according to the power outage situation within 60 days, when the number of power outages within 60 days is once, it is automatically marked as yellow, and when it is two or more times, it is automatically marked as red.

[0035] Among them, the planned maintenance module is used to automatically generate a power outage maintenance plan according to the fault query result when there is a power outage color warning, and automatically send it to the relevant responsible persons. Specifically, a power outage warning plan is generated when there is a yellow warning, and a power outage maintenance plan is generated when there is a red warning.

[0036] Specifically, the power outage maintenance plan has a higher priority than the power outage warning plan.

[0037] Among them, the plan approval module enables relevant responsible persons to quickly complete the approval of power outage maintenance plans by directly viewing the fault query results.

[0038] Among them, the human-computer interaction module includes a user interface located at the WWW browser end and a management interface located at the server end.

[0039] Specifically, according to the query needs, through the user interface, the recent power outage times of the same line within different time ranges such as one day, one month, two months, six months, or one year can be queried, including the total power outage times, planned power outage times, fault power outage times, and emergency repair power outage times.

[0040] Specifically, the fault query work can be triggered manually by humans, which is applicable to the regular maintenance plan every year, or can be automatically triggered by the system according to preset requirements, which is applicable to situations such as high fault occurrence, peak power consumption, or automatic warning.

[0041] Specifically, the database module, security authentication module, fault query module, fault warning module, planned maintenance module, and plan approval module are uniformly configured on the remote server side.

[0042] To follow the principles of practicality and reliability, this system adopts the B / S mode, which has the advantages of strong data processing ability, good interactivity, and high security. By using VNC server software, files are shared on the Internet to enable the client to directly read data from the ORACLE database. The software settings are simple, the functions are powerful, and the performance is stable. The WEB browser is the main application software on the client side. This mode unifies the client side and centralizes the core part of the system function implementation on the server, simplifying the development, maintenance, and use of the system. As long as a browser is installed on the client, data interaction with the database can be carried out through the Web Server.

[0043] In summary, the power distribution network line fault query and warning function provided by the present invention based on the OMS platform enables the line fault information to be clearly visible in this system, facilitating the management of power distribution network lines. And when approving the power outage plan, the power outage situation of this line can be directly seen. If it is found that the number of trips exceeds 2 times within 60 days, an early warning can be directly given to avoid frequent power outages in the line plan, facilitate the reasonable arrangement of power outage plans, minimize repeated power outages, and provide high-quality power services.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that modifications or equivalent replacements can still be made to the specific implementation manners of the present invention. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered by the scope of the claims of the present invention.
