Description

Technical Field

[0001] The present invention relates to the technical field of substation monitoring and management, and in particular to an online real-time monitoring and management method and system for substation personnel. Background Art

[0002] A substation is a place in the power system that transforms voltage and current, receives and distributes electric energy. Substations use transformers and other equipment to convert high-voltage electricity into low-voltage electricity suitable for use in homes and businesses, or convert low-voltage electricity into high-voltage electricity for long-distance transmission; they transmit the electric energy in the power system to every corner of the power grid, and can be understood as the "node" of the power system; they mainly include electrical equipment such as transformers, circuit breakers, grounding switches and electric energy metering devices.

[0003] Substations can be divided into different types according to their voltage level and function, such as step-up substations and step-down substations. Step-up substations are mainly used to step up the voltage of the power generated by the generator and feed it into the high-voltage power grid, while step-down substations are responsible for reducing the high-voltage electricity to a voltage suitable for users. A 500kV substation refers to a substation with a maximum voltage level of 500kV, and its input and output voltages are 500kV and 220kV respectively.

[0004] With the continuous progress and development of science and technology, it is very necessary to monitor transformers. The main reasons include ensuring the safe operation of the power grid, preventing electrical fires, and timely discovering and repairing potential faults; ensuring the safe operation of the power grid is one of the important reasons for monitoring transformers. Through the intelligent monitoring system of the distribution room, the status and operating parameters of the transformer and its related equipment can be monitored in real time, including changes in current, load and power. These monitoring data can help analyze whether the line is overloaded or the power exceeds the limit, and whether the transformer is overloaded, so as to determine whether the working state of the transformer is reasonable and whether it conforms to the current operation mode. During peak load periods, seasonal changes, major political activities, important power supply periods, special meteorological periods and other extraordinary periods, it is particularly important to strengthen operation monitoring in order to promptly detect changes in operating parameters or load anomalies to ensure the safe and stable operation of the power grid.

[0005] For example, the application number is 202110984811.X, which is a method and system for intelligent safety management of substations based on big data. By real-time collection of the status and parameters of each device in the substation and real-time analysis, it is easy to find and deal with abnormalities in the equipment in time, and prevent them from further expanding and forming accidents. At the same time, combined with the real-time collection of equipment operation data and monitoring screens, it can manage and control each area in the substation and the equipment in each area in real time, so as to achieve the effect of timely discovery of equipment abnormalities, timely resolution and prevention. However, the system still has certain defects;

[0006] It is limited to fault monitoring and alarm of substation equipment, but it is unable to record and store fault information. When substation equipment fails, the staff cannot quickly understand whether the cause of the equipment failure is the first or multiple times, which reduces the staff's efficiency in troubleshooting substation equipment failures and cannot quickly evaluate the service life of substation equipment.

[0007] Therefore, we propose an online real-time monitoring management method and system for substation personnel in order to solve the above-mentioned problems. Summary of the invention

[0008] The purpose of the present invention is to provide a method and system for online real-time monitoring and management of substation personnel, so as to solve the problem raised by the above background technology that the substation monitoring system on the market is heavy and limited to fault monitoring and alarm of substation equipment, but cannot record and store fault information. When the substation equipment fails, the staff cannot quickly understand whether the cause of the equipment failure is the first or multiple times, thereby reducing the staff's efficiency in troubleshooting substation equipment failures and unable to quickly evaluate the service life of the substation equipment.

[0009] To achieve the above object, the present invention provides the following technical solution: a method and system for online real-time monitoring and management of substation personnel, the method comprising the following steps:

[0010] Step (a): Substation personnel can monitor the real-time images and conditions of the substation through the video monitoring system. Multiple camera components are installed in the substation. The camera components can record the real-time images and conditions of the substation and transmit them to the cloud server, and then transmit them to the terminal of the substation personnel, so as to facilitate real-time monitoring by the substation personnel;

[0011] Step (ii): Monitor the temperature, humidity, air quality, smoke, and water leakage in the substation through the remote sensing means of the environmental data detection system. When it is detected that there is a lot of smoke in the substation, the alarm system can be triggered. The alarm system is connected to the fire protection system. The alarm system can trigger the fire protection system to realize the automatic fire protection function while the alarm is sounded;

[0012] Step (III): Substation personnel can operate the substation equipment through the remote control system, and can adjust the parameters of the air-conditioning equipment, ventilation equipment and water pump equipment in the substation according to the operating status of the substation, so that the operating parameters of the air-conditioning equipment, ventilation equipment and water pump equipment can ensure that the substation is always in the best operating state; at the same time, the substation equipment is operated through the remote terminal, including switch equipment and adjustment parameters;

[0013] Step (IV): During the operation of substation equipment, substation personnel can use the status assessment system to periodically assess substation equipment and transmit the assessment data to the data analysis system. The data analysis system analyzes and processes the data, extracts useful information and identifies potential problems and risks in the substation. Based on predefined rules and thresholds, the status assessment system can send real-time early warning notifications and generate reports to facilitate trend analysis and decision support for substation equipment status.

[0014] Step (five): When a substation equipment fails, the fault information of the equipment is identified and recorded through the fault warning system, and the information is transmitted to the cloud server through the fault warning system, and then transmitted to the staff terminal through the cloud server. At the same time, the fault information can be broadcasted through the artificial intelligence voice system, and the fault information is recorded and stored.

[0017] Preferably, in step (iii), the auxiliary equipment in the substation is controlled by a remote control system without manual fixed-point control, which can greatly reduce personnel scheduling and improve the operating efficiency of the equipment in the substation.

[0018] Preferably, in step (iv), custom rules and thresholds are set in the status assessment system, such as the temperature and noise generated during the operation of the substation, and the data are set in a standard floating range to automatically assess the status of the substation.

[0019] Preferably, in the step (five), the fault information of the substation is stored and a fault report is generated. When the fault information of the substation is consistent with the cause of the previous fault information, the fault warning system can transmit the alarm record of the repeated cause of the fault information to the staff terminal while sending the alarm information, so as to facilitate the staff to quickly troubleshoot and repair the equipment fault. At the same time, the fault warning system of the fault-reporting equipment can view the historical fault information of this equipment, thereby improving the staff's judgment on the service life of equipment faults.
