Intelligent Distribution Network All-around One Click Transfer Supply Technology
摘要
Abstract
In extremely harsh weather or special operating conditions of the power grid,the loss of electrodes from the superior power supply can easily cause large-scale power loss in the distribution network.In the traditional fault handling mode,experienced dispatchers can restore power to more than ten distribution lines through the main station of the distribution automation system,which may take more than an hour.After research,it has been found that in the case of large-scale power loss in the distribution network,when the fault point is not on the distribution line,there are difficulties in determining the occurrence of large-scale power loss faults and difficulties in quickly and reasonably restoring power due to the large number of power loss lines and connections.In the article,by connecting the interface between the main station of the distribution automation system and the main network automation main station system,achieving the data and graphical models integration of the main network and distribution network.The full telemetry on the substation side,remote signaling information,and graphical and model parameters are connected to the real-time monitoring of the distribution main station.At the same time,a judgment logic for large-scale power loss in the distribution network is developed and deployed to the distribution main station as a condition for initiating the rapid power restoration function.After the function is activated,by monitoring and calculating the load rate of the distribution lines before power loss,the distribution main station automatically provides a power restoration plan,which can be executed with one click.Tests have shown that the self-healing strategy of this technology is simple,flexible,and easy to operate and maintain,with low investment and quick results.It has achieved a change in the load of distribution network lines from"manual transfer"to"program transfer,"and the time required for load transfer has been reduced from hour level to minute level,solving problems such as slow operation,long time consumption,and low restoration efficiency.It has improved the emergency recovery ability of the distribution network,shortened power outage time,reduced power outage losses,and minimized the scope of power outages caused by accidents or maintenance,which is of great significance for ensuring social power supply safety.关键词
