With the rapid development of urban power grid construction, the important role played by distribution automation systems in the safe and reliable operation of power grids has become increasingly prominent. Power grid operation management departments at all levels must strengthen the construction and management of distribution automation systems through effective means. Its application ability in power production operation ensures the safe and stable operation of the power grid.
1. Accelerate the construction of distribution automation system, which is conducive to the process of building a "big operation" system.
Since the opening of the “Great Operation†system, the specialization of “integration of land and county adjustment businessâ€, “integration of land allocation and adjustment business†and “integration of battalion adjustment and adjustment business†has been gradually implemented, and the power grid dispatching automation system has been implemented. Platform construction is even more important. Especially in the process of implementing the “first-class distribution networkâ€, it is conducive to improving the standardization, specialization, leanness, and intensive management level of regional regulation, realizing the integration and integration of the system, strengthening the homogenization management of the county, and improving the reliability of power supply. Sex and voltage qualification rate, thus effectively promoting the "big operation" system construction process.
2. Accelerate the construction of distribution automation system, which is conducive to the operation and maintenance management of automation platform.
Automation platform operation and maintenance management related to the integration and transmission of grid operation related data, only timely update equipment maintenance and maintenance, improve the technical gold content, in order to monitor the accuracy of the substation automation basic data in real time, in order to strengthen the plant terminal equipment elimination management, to ensure State estimation telemetry pass rate and other automation key indicators control. At the same time, speed up the construction of distribution automation system, and provide basic conditions for defining the demarcation of distribution automation terminal management responsibilities and forming a standardized management process for terminal equipment configuration, commissioning, maintenance and defect processing.
3. Accelerate the construction of distribution automation system, which is conducive to the construction of smart grid dispatching technical support system.
The construction of smart grid is the trend of power grid development. As a professional system of power distribution automation supported by smart grid dispatching technology, it can only provide powerful technical support for smart grid dispatching through the application of high, new and sophisticated technologies. The D5000 construction of the smart grid dispatching technical support system carried out by the current power supply enterprise has promoted the transformation of the data plane dual-plane access of the substation automation business, standardized the power access management of the plant automation equipment, and better realized the substation of the region 110kV and below. The data network first and second plane secondary security equipment is fully covered.
Second, improve the power distribution automation application ability several countermeasuresTo improve the practical ability of distribution automation, expand the application scope of distribution automation system, and improve the construction level of "first-class distribution network", the following measures should be implemented in conjunction with the actual operation of the local distribution network:
1. Optimize the normal operation mode of the distribution network.
The high-quality distribution network operation mode is a reliable guarantee for the safe operation of the power grid. In the process of construction of distribution automation system, according to the actual structure of the local grid structure and the operation platform of the dispatching automation system, we should make overall plans and take into account the different network architectures of different partitions to establish a differentiated operation mode strategy, focusing on improving the reliability of power supply in the core area of ​​the city. . At the same time, through the distribution network operation monitoring workbench, timely grasp the transaction information of important indicators such as distribution network reliability and line loss, and timely adjust the distribution network operation mode to ensure the safe and economic operation of the distribution network. Thereby achieving the network advantage through the distribution network, realizing the load interconnection and mutual supply between the power supply areas during the power failure maintenance of the main network equipment, reducing the load loss caused by the maintenance of the main network equipment, and maximizing the function of the distribution automation system. .
2. Accelerate the upgrading and transformation of distribution automation equipment.
With the development of the first-class distribution network, in the process of implementing the distribution automation upgrade, it is necessary to speed up the distribution network related equipment, especially the transformation of distribution automation, increase the wireless public network access function, and realize the fast intelligent circuit breaker fault information. The collection and monitoring, improve the coverage of distribution automation, and expand the advanced application functions of the main station system. At the same time, it is necessary to elaborate the application implementation plan of the distribution automation system, strengthen the operation and maintenance of the main station and terminal equipment, and explore the automatic remote control operation after the feeder automatic startup, fully improve the fault identification ability of the automation system after the distribution network failure occurs, and reduce the power failure range. Improve power supply reliability.
3. Improve the basic management of the distribution automation main station system.
The basic management of the distribution automation master station system is related to the accuracy of a series of basic data. It is necessary to establish a coordination and coordination mechanism for the distribution equipment pattern, and to achieve the closed loop of the management process through the optimization of the interface program between the production PMS system, the distribution automation system, and the five-proof drawing management system, and to ensure the basic diagram of the distribution automation main station system. The accuracy of the model realizes the “source only†of the power distribution equipment pattern of each system, so that the basic data such as the power distribution equipment pattern is accurate and standardized.
4. Set up a distribution network repair command technology platform.
After the implementation of the "big operation" system, the distribution network repair command function is assigned to the power grid regulation department, and the application capability of the distribution automation system is enhanced. The functional departments at all levels should strengthen the coordination between the distribution network regulation and the repair and command business, accelerate the construction of the distribution network repair command platform, and realize the real-time fault judgment analysis of 95598 repair, distribution automation, dispatch automation and power consumption information collection. Especially when the power grid is faulty, the power outage user information is automatically analyzed. At the same time, the power outage range is displayed on the GIS geographic map, the precise location of the power outage range is realized, and the command efficiency of 95598 work order receiving, dispatching and repairing is improved.
