Main distribution network accident recovery processing method based on index set weight

Abstract

The invention relates to a main distribution network accident recovery processing method based on the index set weight. The method comprises the steps of analyzing a main network power loss area according to a network topology model after receiving a fault device, analyzing all main network power restoration paths according to a layered and partitioned fault recovery method, obtaining a main network power restoration result, and sequencing the priorities of the intelligently generated plan sets according to the weights of the index sets. After the main network recovery scheme is analyzed, if a10kV bus without power recovery still exists or an out-of-limit 10kV bus exists after load flow calculation, the distribution network performs power recovery or power transfer on the capacity gap meeting the 10kV bus according to the capacity transfer gap and the radial network topology structure, and configures each weight coefficient value of each group of power recovery scheme; and priority ranking is carried out on the distribution network side schemes to form a unified and complete main distribution network power restoration path strategy. The method is helpful for knowing the safe and stable state of the power grid in time, can obtain decision support of accident handling in advance, and has important significance for improving the capacity of dispatching operation personnel for handling major faults of the power grid.

Description

technical field [0001] The application belongs to the field of electric power data processing, and in particular relates to a recovery processing method for main distribution network accidents based on index set weights. Background technique [0002] With the rapid construction and development of large urban power grids, the interdependent operating characteristics of the main and distribution networks have become increasingly prominent. The emergency response to the sudden failure of the main network urgently requires the integration of the coordination and control of the main distribution. How to take effective measures to minimize the scope of power outages, shorten the time of power outages, prevent the expansion and spread of accidents, and restore power supply as soon as possible on the basis of accurately locating power grid faults is a very important research topic in the field of dispatching automation systems. In terms of load transfer and power outage plan analysi...

Problems solved by technology

In terms of load transfer and power outage plan analysis, although the distribution network self-healing main distribution network linkage control has been realized, in the further load optimization calculation of the transfer line and the non-stop power-off loop closure calculation during the recovery process of the transport party , because a large amount of distribution network operation data cannot be easily shared with the main network system, and the relevant algorithm modules of the main network cannot be conveniently called in the distribution network system, resulting in the lack of corresponding data and application support for optimization, coordination, processing and analysis, and the functions are not practical. low accuracy
