[0003] First, the basic data of the production system and the marketing system do not correspond to each other, and there is a lack of a data sharing platform: when a regional power outage occurs, it is necessary to manually match the name of the substation according to the power outage area displayed by the main station of the distribution automation system, and then notify the emergency repair personnel to repair the household; when a single substation fails and the power outage occurs, the power outage information can only be obtained through the repair work order or the feedback from the on-site power supply station, and there is no channel to prompt the monitoring and command personnel in real time;

[0004] Second, the collection of power outage data currently relies on marketing metering devices, and there is no overall analysis and management platform for the entire network. In particular, the analysis of frequent power outages needs to be carried out manually, which is inefficient.

[0005] Third, there is a lack of developmental analysis and utilization of distribution network operation data, making it difficult to cope with changes in load demand and adjustments in energy structure.

[0006] Therefore, there is an urgent need for a distribution network active repair system based on the integration of operation, distribution and dispatching to solve the above problems. Real-time monitoring of the operating conditions of the residents, substations and lines is carried out to achieve the integration of operation, distribution and dispatching in business, thereby improving the efficiency of active repair and power grid operation.

[0043] Example:

[0044] like Figure 1-2 As shown, this embodiment provides a distribution network active repair system based on the integration of operation, distribution and dispatching, including:

[0045] The power outage real-time monitoring module is used to: monitor power outages of lines, substations and users in real time and display power outage information. When a power outage occurs, it can locate the fault point, pop up a power outage event reminder, and publish power outage information and emergency repair work orders;

[0047] The voltage anomaly analysis model is used to: collect the distribution network line topology and line voltage data in real time, and promptly detect and pop up windows to remind you to deal with overvoltage and low voltage situations;

[0048] The grid open capacity calculation module is used to: collect transformer and line operation data in real time, automatically calculate the distribution network open capacity, and use the calculation results to support the construction of new energy in the distribution network and adapt to changes in load demand and energy structure adjustments.

[0049] Carry out data governance and data synchronization, synchronize line information, substation ledgers, substation transformer operation data, user ledgers and user smart meter operation data to the distribution network proactive repair system, and match the basic information of the production system and the marketing system. At the same time, the distribution automation system fault information is synchronized to the distribution network proactive repair system.

[0050] The substation ledger parameters include but are not limited to the distribution name, ID, the distribution line, the affiliated unit, etc. At the same time, the substation manager information is added and maintained by each power supply center, mainly including name and contact number for SMS notification; the user ledger parameters include user name, contact information, substation, etc., which are maintained by each power supply center and used for power outage statistics; based on the substation information and user information, matching mapping of distribution and users is performed.

[0051] Real-time power outage monitoring section: conduct real-time monitoring of power outages for lines, substations, and users and display power outage information; when a power outage occurs, automatically locate the fault point, pop up a power outage reminder, and publish power outage information and emergency repair work orders at the same time; can be displayed according to line power outages, substation power outages, and user power outages. Click on a power outage event to view the details of the power outage event and the scope of the power outage.

[0052] The details of the power outage event include the location of the fault point, the power outage equipment, the power outage recovery status, the duration of the equipment power outage, etc.; the scope of the power outage includes the power outage area, the number of private / public transformers affected by the power outage, the details and the list of affected users, marking of important and sensitive users, frequent power outage equipment and user conditions, etc.

[0053] In the real-time power outage monitoring section, when a power outage occurs, the distribution automation system senses the power outage and conducts fault section analysis.

Pop-up reminders are displayed for abnormal data in areas with frequent power outages.

[0060] The frequent power outage warning and analysis section supports multi-dimensional analysis of power outages in substations and users based on fixed cycles such as days, weeks, months, and years, or customized cycles, including responsible units, causes of power outages, repeated power outages, year-on-year and month-on-month conditions, etc., providing data support and decision-making basis for professional management and grassroots power supply units.

[0061] Voltage anomaly analysis section: Real-time collection of distribution network line topology and line voltage data, timely detection and pop-up reminder to deal with overvoltage and low voltage situations, and prevent risk complaints in advance.

[0062] The voltage anomaly analysis section focuses on monitoring users or substations with abnormal voltage for ≥2 days in urban areas, ≥3 days in rural areas, and ≥5 days in special remote areas in the past three months. When abnormal voltage data is detected, a pop-up window will be displayed to remind you to deal with the abnormal voltage situation and prevent risk complaints.

[0063] Grid open capacity calculation section: Real-time collection of transformer and line operation data can automatically calculate the open capacity of the distribution network. The calculation results are used to support the construction of new energy in the distribution network and adapt to changes in load demand and adjustments in energy structure.

[0064] The open capacity calculation section of the power grid needs to collect the allowable current carrying capacity, annual maximum current consumption and power capacity to be connected of the distribution network trunk lines, and the platform can automatically calculate the open capacity of the distribution network.
