[0002] The transmission network is a power transmission network that connects power plants, substations or substations, and is mainly responsible for the transmission of electric energy. According to the transmission voltage, it can be divided into high-voltage transmission network, extra-high-voltage transmission network and ultra-high-voltage transmission network;

[0003] The transmission network is composed of transmission equipment and substation equipment. The transmission equipment mainly includes transmission lines, towers, insulator strings, empty lines, etc. The substation equipment mainly includes transformers, reactors, capacitors, circuit breakers, grounding switches, lightning arresters, voltage transformers, current transformers, as well as power protection, monitoring, control, and communication systems.

[0004] In recent years, due to the aging of power supply lines and equipment, busbar tripping accidents have occurred from time to time in transmission lines, resulting in a greater risk to the quality of power supply services. When a customer loses power, the existing power supply system is not fast enough to obtain power outage information, and each professional and level needs to be notified by telephone step by step. The information exchange takes a long time and may cause information backflow. In addition, the logic for judging customer power outages is single and has low accuracy. Summary of the invention

[0055] In one embodiment, an emergency fault response is initiated based on the customer classification level, the full factor database, and the customer's power usage status, including:

[0056] When the customer's power status is power outage and the customer's customer classification level is an important customer, the message data is obtained, and a preliminary disposal group and an analysis and judgment command group are established based on the full-factor database, and the relevant staff are automatically notified by phone and text message to carry out preliminary disposal and analysis work;

[0057] When the customer's power consumption status is power outage, and the customer's customer classification level is not an important customer, the message data is obtained and pushed to the corresponding regional power outage handling group and the corresponding power supply station power outage handling group based on the full-factor database, and the relevant staff are automatically notified by phone and SMS to carry out fault handling work, and the top level of the fault is defined according to the number of power outage households and the number of frequent power outages, and a customer list of the customer classification level involved is automatically pushed;

[0058] The working principle and beneficial effects of the above technical solution are as follows: according to the importance of the customer, establish the standards for initiating emergency and fault response; divide the customer power outage response into four stages: initiating consultation, consultation and analysis, response disposal, and response review; in the initiating consultation stage, if the customer's power status is a power outage and the customer's customer classification level is an important customer, RPA automatically captures the message data and triggers the establishment of a group, that is, an early disposal group and an analysis and judgment command group are established based on the full-factor database, and automatically notifies relevant staff by phone and text message to carry out early disposal and analysis work. At the same time, it automatically pushes a list of four types of customers and a one-household-one-policy emergency protection plan; and when the customer's power status is a power outage and the customer classification level is not When it is an important customer, RPA automatically captures message data and pushes it to the group. Based on the full-factor database, it pushes it to the corresponding regional power outage handling group and the corresponding power supply station power outage handling group, automatically notifies relevant staff by phone and text message to carry out fault handling work, and defines the top level of faults according to the number of power outages and the number of frequent power outages, and automatically pushes a list of customers involved in the customer classification level; subsequent consultation and judgment, response and handling, and response review are generally conducted by staff in the consultation and judgment stage, holding a telephone conference, verifying the incident situation, and proposing response classification suggestions. After approval by the commander-in-chief, the fault response is initiated, and the initial information reporting caliber is determined; in the response and handling stage, standard terms and push materials within the group are sorted out in advance, and work tasks are assigned. During the response review stage, improvement measures are proposed to optimize processes and fill in missing links in multiple dimensions such as power grid planning, fault repair, and customer service. Each stage will be different and can be carried out according to the execution standards set in advance for each classification level. For example, the consultation and assessment of important customers is to hold a telephone conference through iState Grid to verify the incident situation, put forward response classification suggestions, and initiate fault response after approval by the commander-in-chief; determine the scope of initial information reporting, and the company leaders and professional departments shall report to the counterparts according to the division of responsibilities; response and disposal is to establish a professional disposal group and assign tasks; each professional department shall promptly feedback the situation to the group; guide customers to start the second power supply or self-provided emergency power supply to provide grid services and stability maintenance in accordance with the division of tasks; response review is to optimize processes and fill in missing links in multiple dimensions such as power grid planning, fault repair, and customer service; dual power supplies are used at the same site for important customers; among them, the customer classification level list is established when the customer classification level is divided.

[0059] In one embodiment, digital intelligence support is strengthened to establish a customer electricity monitoring platform. Based on the energy big data application support platform, combined with business professional platforms such as the power grid map, PMS3.0, procurement system, marketing service system, and dispatching system, digital tools such as process robots, measurement centers, and data middle platforms are used to establish a panoramic display platform for electricity monitoring visualization. The customer's power supply voltage, current and other information are displayed in real time, and early warning reminders are issued for power failures; at the same time, the power-on and power-off events, equipment operating status, and power outage repair work order information are connected to display the progress stage of power outage disposal, helping monitoring personnel to understand the customer's electricity usage.
