Research on the Key Technology of Urban Distribution Network Scheduling Support System

Under the background of the rapid development of the distribution grid, the original dispatching support system cannot meet the requirements of power supply reliability. For this reason, the key technology of the urban distribution network dispatching support system was proposed and studied. Introduced the map mode data system and the power grid database management system, combined with the server and workstation configuration to complete the design of the urban distribution network scheduling support system. Based on the system structure, the three parts of graph and mode integration, distribution network topology design and system risk assessment were studied as key technologies. The layout structure of electrical components was optimized by drawing and modeling integrated system. A method of automatic conversion of electrical topology to power flow topology was proposed to optimize the topology of distribution network. Data clustering analysis was used to help complete the system risk assessment, and the construction of urban distribution network dispatching support system was realized by integrating key technology analysis. By comparing the changes of the key indicators before and after the implementation of the system, all the indicators have been improved, and after comparing with the traditional system, the power supply reliability after the optimization of the system has been greatly improved, reaching about 95%, which provides a theoretical basis for the effective application of the urban distribution network dispatching support system.
