Backup Power Automatic Input Of Xie Zhuang 110kV Substation

With the accelerated pace of construction of power grids, grid ring appeared in a variety of electromagnetic problems, electromagnetic loop network problem has gradually threaten the normal operation of the grid, in order to reduce the risk of grid operation, the grid strategy progressively implemented understand ring, ring after solution corresponding power grid reliability will fall, in order to avoid new problems after the solution ring brings, it is necessary to consider the application of the grid prepared from the cast device.After the solution ring, new problems will cause a short circuit current of the power grid is increased, in addition to equipment malfunction solution ring N-1 will lead to the appropriate site after voltage stability problems arise. In BZT issues, how to perform the corresponding function module logic configuration tuning and related technology research, it will be a very important technology, which is of great significance for improving the accuracy of device operation.Device considering inputs provide power supply reliability can be greatly load the site, but the technology bottleneck problem currently facing device considering how to put to use, reasonably put to use device considering not only improve the reliability of power supply, but also to meet energy quality requirements. Based on the above background to Xie Zhuang 110kV substation for the case to conduct a study on transfer switch Xie Zhuang plant operation and operating characteristics of the status quo to start analysis, multi-function device considering logic modules to expand the research, and then to start from the perspective of protection of XIE Zhuang 110kV substation automatic switching power Automatic control Strategy. By analyzing Xie Zhuang 110kV station project, prepared from the cast of the previous system problems were analyzed, including the logical connection, and an outlet circuit protection and other aspects. Finally, the corresponding improvement strategy and operation and maintenance methods. This study for the application of equipment in 110kV substation automatic switching provides a good example for reference works.
