Embodiment Construction

[0022] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.

[0023] The present invention provides a feeder automation function detection system. The detection system includes a distribution automation system basic data platform 1, a feeder fault simulation module 2, a feeder analysis module 3, a feeder fault simulation detection platform 4, and a distribution automation system under test 5 .

[0024] The basic data platform 1 of the distribution automation system is used to analyze the faults in the actual distribution network, summarize the signal changes on the feeder line when the fault occurs, and form a predefined fault signal generation mode.

[0025] The feeder fault simulation module 2 is configured to import a power grid model running in real time, receive the fault information in the fault concentration output by the feeder fault simulation detection p...

Abstract

The invention provides a feeder automation function detection method, which includes the following steps: analyzing typical faults in distribution networks, defining a general predefined fault signal generation mode and processing scheme; the feeder fault simulation detection platform uses a real-time power grid model, based on the preset The defined feeder fault mode generates the corresponding fault simulation signal and the corresponding fault processing plan; the distribution automation system under test receives the simulated fault signal, generates and executes the fault processing plan according to its own set strategy; the feeder fault simulation detection platform receives and communicates with the predicted Define treatments for comparison. The present invention generates a fault signal by using a predefined fault mode, and injects it into the power distribution automation system to be tested, triggering the fault processing function of the system to be tested; receiving the fault processing scheme of the system to be tested online and generating and (or ) compared with the manually set fault handling schemes, and automatically generate the detection results.

Description

technical field [0001] The invention relates to the field of power system distribution automation, in particular to a feeder automation function detection system and method. Background technique [0002] In recent years, the country has vigorously carried out the construction of distribution automation systems, and strived to improve the quality and reliability of power supply, and the feeder automation processing is an important basic functional module in the distribution automation system. The proposal and configuration of this function provide the possibility to quickly deal with the faults in the distribution automation system; with the help of this technology, the users of the distribution automation master station system can quickly complete the analysis of sudden faults and find the cause of the fault. The solution is to isolate the faulty area and restore power to the non-faulty area, so as to improve the stability and reliability of the power supply as much as possi...
