I. Introduction. With the continuous development of the power system, the importance of substation operation and maintenance technology has become increasingly prominent. As an important part of the power system, the safe and stable operation of the substation is essential to ensure the reliability of the power supply. This article will focus on the relevant issues of substation operation and maintenance technology and product selection.
Second, substation operation and maintenance technology.
1.Routine maintenance techniques.
Conventional maintenance technology is the basis for ensuring the normal operation of the substation, mainly including equipment inspection, condition monitoring and fault diagnosis. Through regular inspection, equipment abnormalities can be found in time; Condition monitoring is based on real-time data collection and analysis, and the problems that may occur in the equipment are improved; Fault diagnosis is based on the accurate location and cause analysis of the faults that have occurred.
2.Intelligent maintenance technology.
With the development of technologies such as the Internet of Things, big data and artificial intelligence, intelligent maintenance technology is becoming more and more widely used in the field of substation operation. Through the establishment of an intelligent maintenance system, the operation status of the substation can be monitored in real time, abnormalities can be automatically identified, and corresponding treatment measures can be taken. This technology not only improves maintenance efficiency, but also effectively reduces operation and maintenance costs.
3. Introduction and selection of the operation and maintenance system of Ankerui substation.
3.1 Overview.
ACRELCLOUD-1000 substation operation and maintenance cloud platform is a cloud management platform developed based on the Internet, big data, mobile communication and other technologies, which meets the needs of users or operation and maintenance companies to monitor the operation status and parameters of many substation circuits, indoor environmental temperature and humidity, cable and bus operation temperature, field equipment or environmental scenarios, etc., to achieve data centralization, centralized storage, unified management, easy to use, and support users with permissions to access through various terminal links such as computers, mobile phones, pads, etc. Receive alarms, and complete management work such as daily and regular inspection and dispatch of equipment.
3.2. Application place.
It is suitable for the new construction, expansion and reconstruction of substation and distribution operation and maintenance systems in telecommunications, finance, transportation, energy, medical and health care, culture and sports, education and scientific research, agriculture, forestry and water conservancy, commercial services, public utilities and other industries.
Fourth, system functions.
4.1. Monthly report on energy consumption.
The monthly report of energy consumption allows users to query the electricity consumption of the managed stations according to the total electricity consumption, substation name, substation number, etc., and the query span can be set to month.
4.2. Site monitoring.
Site monitoring includes overview, operation status, event records of the day, hourly electricity consumption curves of the day, and electricity consumption overview.
4.3. Transformer status.
The transformer status supports users to query the transformer power, load rate, and other operating status data of all or a certain station, and supports ranking in ascending and descending order according to load rate and power.
4.4. O&M.
O&M displays the location and total amount of substation location on the map managed by the current user.
4.5 power distribution diagram.
The power distribution diagram displays the power distribution information of the selected substation, and the power distribution diagram displays the operation status and information such as switching status and current of each circuit, and supports the query of detailed operating parameters such as voltage, current, and power.
4.6** Monitoring.
*The monitoring shows the current real-time screen (**live broadcast), select a substation, and you can view the ** information in the substation station.
4.7. Power operation report.
The power operation report displays the real-time value and average value of the specified collection interval of each circuit of the selected station, the selected equipment, the operation parameters and the electric energy meter reading.
4.8. Alarm information.
Analyze all alarm information on the platform.
4.9. Task management.
On the task management page, you can publish inspection or defect elimination tasks, view the status and completion status of inspection or defect elimination tasks, and click View Tasks to view specific inspection information.
4.10 User Reports.
The user report page is mainly used to automatically summarize the operation data of the selected substation for one month, statistically analyze the transformer load, power consumption of the distribution circuit, power factor, alarm events, etc., and list the various defects found during the inspection and the treatment status during the inspection.
4.11 APP monitoring.
The power operation and maintenance mobile phone supports seven modules: "monitoring system", "equipment file", "to-do list", "inspection record", "defect record", "document management" and "user report", and supports a map, demand, power consumption, curve, temperature and humidity, year-on-year, ring comparison, power quality, various event alarm query, equipment file query, to-do event processing, inspection record query, user report, document management, etc.
5. System hardware configuration.
VI. Conclusions. Substation operation and maintenance technology is the key to ensure the safety and stability of the power system, and reasonable product selection is an important prerequisite for efficient operation and maintenance. In the future development, it is necessary to further increase the research on substation operation and maintenance technology, and promote the development of intelligent operation and maintenance technology to improve the overall operation level of the power system.
