Main and distribution network intelligent linkage system and fault full-stop full-transfer implementation method

Abstract

The invention discloses a main distribution network intelligent linkage system and a fault full-stop full-rotation realization method, and the system comprises an intelligent linkage device which is connected with a bus and is used for collecting a bus signal, carrying out the charging and discharging operation, and judging whether the bus has a fault or not; and the scheduling module is connected with the intelligent linkage device and is used for executing load transfer and / or reverse delivery operation according to the data provided by the intelligent linkage device. The method is used for intelligently identifying the fault type, calculating the load capacity to be transferred in real time and accurately switching and transferring loads in the whole network range in combination with the transfer channel limit when the transformer substation is fully stopped due to the main network fault or the 10kV bus in the transformer substation loses power and the spare power automatic switching failure occurs, and the fault recovery time is shortened.

Description

technical field [0001] The invention relates to the field of power grid fault processing, in particular to an intelligent linkage system of a main distribution network and a method for realizing full stop and full rotation due to faults. Background technique [0002] With the rapid development of local economy and urban and rural construction, the risk of power grid is increasing day by day, and the number of six-level risk warning orders of power grid throughout the year has increased significantly. The measures taken by traditional substations to prevent total shutdown of the power grid risk often adopt strengthened equipment inspections, and the technical measures on the 10 kV side stay in the use of backup and automatic switching in the station. The load restores the 10 kV bus voltage, and the emergency treatment usually takes a long time. The reasons for the existing technology deficiencies, combined with the current processing methods, when the on-duty monitor finds a...
