Abstract

The application discloses a method and system for controlling switching on and off of reclosing gates in a distribution network. The method includes: establishing a reclosing switch on and off fixed value table in the on and off management system, and setting a distribution network switch in the reclosing switch on and off fixed value table. The initial switching status of the reclosing switch; according to the remote signaling value of the charging completion signal of the reclosing switch, the actual switching status of the distribution network reclosing switch is obtained; judging whether the actual switching status is consistent with the initial switching status, and the consistency judgment result is obtained; When the consistency judgment result is inconsistent, the remote control operation pop-up window is loaded, so that the dispatcher can input adjustment instructions in the remote control operation pop-up window according to the operation period of the reclosing switch; adjust the actual switching status according to the adjustment command, and realize the reclosing of the distribution network The whole-process control solves the technical problems of the large number of reclosing switches in the existing distribution network, resulting in heavy workload, long time-consuming and poor timeliness, which greatly reduces the power supply reliability of the line.

Description

technical field [0001] The present application relates to the technical field of distribution network automation, and in particular to a method and system for controlling switching on and off of distribution network reclosing switches. Background technique [0002] The distribution network reclosing switch can automatically reclose the switch in a short time after the distribution network switch trips when the distribution network line equipment fails, so that the line can automatically restore power supply. With the large-scale operation of distribution network automation, higher requirements are put forward for power supply reliability and customer satisfaction. [0003] In the prior art, the control of the reclosing switch of the distribution network is controlled manually, so it is unavoidable that there will be missed switching or failure to switch after timeout. The scheduling operation ticket can prevent the above situation from happening, but it is still necessary t...
