Research And Application Of Distribution Network Operation Monitoring System In Rural Areas

The from the practical work experience of describes the rural distribution network operation monitoring system on-line application, through the operation and condition monitoring and management of rural distribution network research Shanxi, Shandong and other domestic and foreign status, understand the rural distribution network operation and management current situation at home and abroad, and research purpose and significance, combined with their work and deep understanding of rural distribution network of backward technology and equipment, power supply capacity is not strong in the status quo to determine research direction. This paper tells the story of the monitoring system detailed design scheme and technical route, data sources, data formula calculation, solve the major, common technical problems and application examples, a detailed description of the system on-line operation, listed solutions through on-line system before and after contrast list management benefit, social benefit, economic benefit, for rural power network operation maintenance to provide convenient and effective management operation through the difficulties of analysis.Using acquisition system in Taiwan area monitoring data realization of rural power distribution network voltage qualification rate and the power supply reliability rate, the average load rate, loss rate of statistical analysis and query and display, rural power distribution network with changed load and three-phase unbalanced and overvoltage real-time monitoring and analysis to demonstrate.Through management Jinzhong Area monitoring system on-line operation, to solve the system on-line operation of the key and difficult problems, develop reform guiding ideology and guiding method, make the system can successfully complete the online early warning tasks.Through the "monitoring system" over load, the voltage is more limited, three-phase unbalanced case analysis, determine the direction of the system management, the system warning, detailed analysis of distribution transformer are all kinds of problems guide actual rural power grid maintenance, implementation of combining theory and practice, "monitoring system" application to the basic work of the power supply.
