[0041] Instructions for filling database of reconstruction plan

[0042] The network reconfiguration scheme can be filled into the database one by one manually through the interface, or a complete data file can be formed, and then imported into the database by the filling program. The network reconfiguration data file consists of several fault definitions and reconfiguration scheme data blocks, and each data block is filled in the following table format. The parts inside the square brackets are used as data identifiers for the database filling program. Except for the fault identification and fault name that need to be newly defined by the user, other content is taken from the existing data and is consistent with the site.

[0043] The length of various logos supports up to 14 characters, and the length of Chinese names is limited to 14 Chinese characters. Chinese names support mixed Chinese and English, and the database filling program can automatically convert full-width En...

Abstract

The invention belongs to the field of power systems and relates to a typical fault reconstruction method capable of processing a fault of the power system. The key components of the reconstruction scheme comprises a fault definition, a control instruction and indication information; the fault definition comprises the name of the fault, an identifier of the fault and a judging condition; and during formulation of the reconstruction scheme, the influence of a running mode is considered, a running rule is obeyed, and necessary safety pre-checking is performed. Aiming at the faults on the same equipment, different running reconstruction schemes should be formulated respectively; during formulation of the reconstruction scheme, a tripping signal, a switch remote control signal and voltage / current remote sensing data are fully used so as to guarantee that the fault definition and the control instruction are correct; the fault caused by protection malfunction or failure is identified so as to prevent fault expansion, asynchronous parallel, overload of a junctor and a transformer and out-of-limit of voltage; and during execution of network reconstruction, the rule that the original backup power supply device is first is obeyed.

Description

technical field [0001] The invention belongs to the field of power systems, and relates to a typical fault reconstruction method for power system accident processing. 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...
