Development and Application of Intelligent Remote Closing Device for Substation Considering Multiple Emergency Scenarios

With the construction of new power systems continue to promote, substation digitalization of primary and secondary equipment in recent years has been intelligently transformed and upgraded. However, intelligent algorithmic programs, devices and switching drive machinery in the operation process is prone to program necrosis, jams and interruptions faults, in the daily operation of the reverse gate, equipment maintenance process there are often operational interruptions, not only seriously affects the normal action of the protection of the traditional maintenance personnel to deal with the process and method of artificial not only time-consuming and laborious, and on-site processing affects the power grid outage and transmission time, causing a bad impact on the society. The society is badly affected. Text consider substation 35 kV and below switchgear, 110 kV and above button primary switch gate knife equipment abnormalities and failures, and can not field in situ split scene for problem traceability analysis, develop a trajectory based on adaptive tracking, RF linkage method of substation switches, isolation switches remote intelligent tap and close device, can be realized that the device in the specified trajectory process for push-in and push-out, so that the The switch and isolation switch can be quickly opened or closed to realize efficient and accurate isolation of abnormalities and faults. Tests have proved that the use of the device after the switchgear type of opening and closing scenarios to improve the efficiency of 96.5%, button primary equipment emergency disposal scenarios to improve the efficiency of 75.8%, at the same time, to protect the personal safety of the field operators, for the safe and stable operation of the grid to provide security, intelligence, high efficiency protection support.
