Embodiment Construction

[0038] 1.1 General principles for formulating a reconstruction plan

[0039] 1. The components of the reconstruction plan include fault definition, control instructions and prompt information. The fault definition is composed of specific content such as fault name, fault identification, and judgment conditions.

[0040] 2. When formulating the reconstruction plan, the impact of the operation mode should be considered, the operation rules should be followed, and the necessary safety pre-verification should be carried out. For the failure of the same equipment, reconstruction schemes corresponding to different operation modes can be formulated respectively.

[0041] 3. When formulating the reconstruction plan, it is necessary to make full use of the trip signal (including: protection action / switch displacement / failure signal of standby automatic switch), switch remote signal, voltage / current telemetry data to ensure that the fault definition and control instructions are accurate...

Abstract

The invention relates to a network reconfiguration system (Failure Detection, Isolation, and Recovery FDIR) based on CC-2000, belonging to the field of automatic control on electrical power systems. The network reconfiguration system comprises an electrical power system fault diagnosis module, an electric power system recovery control module, a data input and output module, a human-computer interface display module and a network reconfiguration database. The network reconfiguration system is characterized in that the electrical power system fault diagnosis module is used for analyzing a collected telecommanded and telemetered signal and diagnosing a fault; the electric power system recovery control module is used for taking a control strategy for the diagnosed fault; and the data input and output module is used for issuing a control instruction to the electrical power system so that the electrical power system rapidly recovers to supply power. By adopting a shortest path searching method of combining breadth-first and depth-first, rapid recovery for electric power shutdown load is realized through protection action.

Description

technical field [0001] The invention belongs to the field of power system automation, and in particular relates to a CC-2000-based network reconfiguration system (FDIR). 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 blackouts are urgent and important tasks 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 p...
