[Abstract]:Distribution automation system uses modern communication technology, computer and network technology to integrate real-time information of distribution network, grid structure parameters, geographic information and so on. It forms a complete automation management system to realize the monitoring, protection, control and distribution management of normal operation and accident of distribution system. As the most important and complex part of the power grid, the district distribution network is the most important and complex part. It is very important for the users to improve the stability and reliability of the power supply system.
According to statistics, 80%~95% of the blackouts of ordinary residents are caused by distribution network faults. Therefore, in order to solve the blackouts of residents caused by distribution network faults and further improve the reliability of distribution network power supply, various methods such as strengthening the construction of distribution network, researching the automation of distribution network, realizing the rapid location of power grid faults, etc. are combined with marketing department. The horizontal integration between the national grid GIS system and the rush-repair production system can realize the quick and accurate acquisition of the geographical position information of the users, the detailed location of the distribution network faults, the rush-repair dispatch sheet information of the power enterprises, greatly improve the rush-repair timeliness, customer service satisfaction and standardize the management level of the power distribution network. The specific research work is as follows:
(1) Aiming at the problem that there is no reasonable and unified evaluation model for distribution networks with different reliability levels, a comprehensive quantitative model and evaluation criteria for distribution networks are proposed. The numerical normalization scale system converts the actual value of a certain index into the evaluation of the corresponding work level, and establishes an effective index evaluation system, which is comparatively systematic and complete.
(2) Aiming at the problem that the multi-information systems of the power grid can't operate independently and can't carry out the comprehensive analysis and application of a certain business of the distribution network well, the information fusion goal with production as the core is put forward. System data form a virtual large system; do not repeat the maintenance of data, according to different types of data reasonably demarcated boundaries, professional system maintenance professional data, through the macro-unified modeling, to achieve seamless integration of information; to achieve production-oriented marketing, distribution information and business integration.
(3) Distribution automation system is integrated based on distribution information fusion. Aiming at the problem of independent operation of the systems among different services, the evaluation criteria and the establishment of information fusion objectives are put forward from the aspects of operation and maintenance capacity building, operation and management methods of distribution automation system, combined with the comprehensive quantitative model of distribution network, and the establishment of evaluation criteria and information fusion objectives. On the basis of integrated architecture and information interactive bus design and information fusion, an automatic command and repair platform system for distribution production is established to realize the comprehensive application of distribution production and repair.
(4) Through the application of the production and emergency repair command platform of distribution network, the validity of the unified expression of marketing, distribution and other data and the sharing of information with the GIS geographic information system as the "tie" and the IEB as the information exchange bus are verified, and the close vertical and horizontal information integration among the various application systems is realized to serve the customers. It provides a good communication platform between emergency repair personnel and repair personnel, and meets the actual requirements of integration of production and emergency repair command of urban distribution network and improving high reliability of power supply.
