  • Detail

With the rapid development of urban power construction, distribution automation system plays an increasingly important role in the safe and reliable operation of electricity. Power operation management departments at all levels must strengthen the construction and management of distribution automation system through effective means, constantly improve its application ability in power production and operation, and ensure the safe and stable operation of electricity

1. Accelerating the construction of distribution automation system is conducive to promoting the construction process of "big operation" system

since the "big operation" system was launched in the national power system, special work such as "integration of prefecture and county dispatching business", "integration of prefecture and county dispatching business", "integration of business distribution and dispatching" has been gradually implemented, and the construction of power dispatching automation system platform is more important. Especially in the process of implementing the construction of "first-class power distribution", it is conducive to improving the standardized, professional, lean and intensive management level of regional regulation, realizing the system from integration to integration, strengthening the homogeneous management of county distribution and dispatching, and improving the reliability of power supply and voltage qualification rate, so as to effectively promote the construction process of "big operation" system

2. Accelerate the construction of distribution automation system, which is conducive to the operation, maintenance and management of automation platform

the operation and maintenance management of the automation platform is related to the integration and transmission of data related to electrical operation. Only by timely accelerating the update and maintenance of equipment and improving the gold content of technology, can we monitor the accuracy of the basic data of substation automation in real time, strengthen the defect elimination management of plant and station equipment, and ensure the control of key automation indicators such as the qualification rate of state estimation telemetry. At the same time, accelerate the construction of distribution automation system, and provide basic conditions for clarifying the division of distribution automation terminal management responsibilities and forming a standardized management process for terminal equipment configuration, operation, maintenance and defect treatment

3. Accelerating the construction of distribution automation system is conducive to promoting the construction of intelligent power dispatching technical support system

intelligent power construction is the general trend of power development, and the distribution automation professional system, as the technical support of intelligent power dispatching, can provide powerful technical support for intelligent power dispatching only through the application of high, new and advanced technologies. At present, the construction of intelligent power dispatching technical support system D5000 carried out by power supply enterprises has promoted the transformation of data biplane access of substation automation business, standardized the power access management of plant and station automation equipment, and better achieved the full coverage of secondary security equipment in the first and second planes of substation data of 110kV and below in the region

II. Several countermeasures to improve the application ability of distribution automation

to improve the practical ability of distribution automation, expand the application scope of distribution automation system, and improve the construction level of "first-class distribution", the following countermeasures should be implemented in combination with the actual operation of local distribution:

1 Optimize the normal operation mode of power distribution

this ensures the rapid utilization of Raymond's low-cost carbon fiber and the high-quality power distribution operation mode, which is a reliable guarantee for the safe operation of electricity. During the construction of distribution automation system, it is necessary to make overall consideration according to the local frame structure and the actual operation platform of dispatching automation system, establish differentiated operation mode strategies in combination with the network architecture of different zones, and focus on improving the power supply reliability of urban core areas. At the same time, through the distribution operation monitoring workbench, timely grasp the abnormal information of important indicators such as distribution reliability and line loss, and timely adjust the distribution operation mode to ensure the safe and economic operation of power distribution. Thus, the network advantage of power distribution can be achieved to realize the interconnection and mutual supply of loads between power supply areas during the outage and maintenance of main equipment, reduce the load loss caused by the maintenance of main equipment, and maximize the function of distribution automation system

2. Accelerate the upgrading and transformation of distribution automation equipment

with the development of first-class distribution construction, it is necessary to speed up the distribution of relevant equipment during the implementation of distribution automation upgrading, "Solvay polymers is committed to providing automotive manufacturers with the most extensive high-performance automotive polymers in the industry, especially the transformation of power distribution automation, increasing the wireless public access function, realizing the collection and monitoring of fault information of fast intelligent circuit breakers, improving the coverage of power distribution automation, and expanding the advanced application functions of the master station system. At the same time, it is necessary to carefully prepare the application and implementation scheme of power distribution automation system, and strengthen the master station and terminal The operation and maintenance of the equipment, explore the automatic remote control operation after the feeder automation is started, comprehensively improve the fault discrimination ability of the automation system after the distribution failure, reduce the scope of power failure, and improve the reliability of power supply, which has become one of the most troubled industries

3. Improve the basic management of distribution automation master station system

the basic management of distribution automation master station system is related to the accuracy of a series of basic data. It is necessary to establish a coordination and linkage mechanism for the updating of distribution equipment drawings and models. Through the production of PMS systems and the optimization of interface programs between test automation systems, five prevention drawing management systems and other systems with finished products, the closed-loop management process is achieved, the accuracy of the basic drawings and models of the distribution automation master station system is guaranteed, the "source end uniqueness" of the distribution equipment drawings and models of each system is realized, and the basic data such as distribution equipment drawings and models are accurate and standardized

4. Build a technical platform for emergency repair command

after the implementation of the "big operation" system, the command function of distribution and emergency repair is assigned to the power regulation department, and the application ability of distribution automation system is improved. Functional departments at all levels should strengthen the coordination between distribution regulation and emergency repair command business, speed up the construction of distribution and emergency repair command platform, and realize the real-time fault determination and analysis of 95598 repair application, distribution automation, dispatching automation and power consumption information collection. Especially in case of power failure, the power failure user information is automatically analyzed, and the power failure range is displayed on the GIS geographical map, so as to realize the accurate positioning of the power failure range and improve the efficiency of 95598 work order receiving, dispatching and emergency repair command
