[0023] 1 fault definition table

[0024] Table name: fault

[0025]

[0026] 【Example of filling in the form】

[0027] For the tripping fault of the main transformer #1 of the peace transformer, it is assumed that the fault ID is hpfxf1, the station ID is heping (consistent with the st table of the system library), and the corresponding strategy ID is hppxf1.

Abstract

The invention belongs to the field of power systems, and provides a method for constructing a network reconfiguration (FDIR (Fault Detection Isolation Recovery)) database. The network reconfiguration database (fdirdb) comprises a fault definition list, a trip signal list, a remote signaling condition list, a remote metering condition list, an alarm queue list, a strategy list, an instruction list, a global variable list and the like. Discrimination conditions of faults and specific contents of a control strategy are expressed by means of a relation list. Display information of a key frame is provided by the global variable list. In order to accurately express discrimination conditions of various faults and the specific contents of the control strategy, a plurality of relation lists such as fault-trip, fault-remote metering, strategy-instruction and the like are established, a fault-trip device, a fault-remote signaling device, a fault-remote metering device and a self-switching device in the relation lists correspond one to one, and a strategy-instruction relation is a corresponding instruction generated for realizing a reconfiguration scheme. When a database is designed and accessed, the problem of concurrent database reading of an upstream program and a downstream program is avoided, and integrity of original data is ensured.

Description

technical field [0001] The invention belongs to the field of power systems and provides a method for constructing a network reconstruction (FDIR) database. Background technique [0002] In the operation of modern power systems, large-scale power outages in power systems are issues that require great attention. In recent years, there have been many large-scale power outages due to the stability of the domestic and foreign power systems, which have caused great damage to the national economy and greatly affected the society and people's lives. Ensuring the safe and stable operation of the power system and preventing large-scale power outages is an urgent and important task facing the modern power system. On the other hand, once an accident occurs in the power system, how to take correct and effective measures to minimize the scope of power outage, shorten the time of power outage, and restore power supply as soon as possible becomes an issue that is as important as preventing...
