Problems solved by technology

In view of the large-scale distribution network, the large number of lines, and the remote location of some lines, this method is unrealistic. Therefore, a portable feeder automation function test system is designed to be used in cities, counties, companies or engineering sites. Testing the distribution automation terminal in the laboratory environment is of positive significance for verifying its feeder automation function logic and improving its fault handling capability

Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] In view of the existing technology, it is impossible to realize synchronous waveform inversion for multiple distribution automation terminals, and it is impossible to accurately and maximize the simulation of the real fault environment of the distribution network, so as to improve the logic verification ability of feeder automation. At the same time, problems such as testing of distribution automation terminals must be carried out in a non-laboratory env...

Abstract

The invention provides a feeder automation function testing device which comprises a main controller, a real-time digital simulator and a plurality of power distribution terminal testers. The main controller is connected with the real-time digital simulator and connected with the plurality of power distribution terminal testers through a wireless network. Each power distribution terminal tester isconnected with a tested power distribution automation terminal. The main controller is used for building a power distribution network real-time digital simulation model according to the power distribution network frame structure of a tested feeder automation configuration region and an operation mode of the power distribution network frame structure. The real-time digital simulator is used for carrying out real-time simulation according to the power distribution network real-time digital simulation model and generating waveform files of different network nodes on the same section. The feederautomation function testing device provided by the invention can test the power distribution automation terminal in a non-laboratory environment, and has a positive significance for popularization offeeder automation function testing.

Description

technical field [0001] The invention relates to the field of electric power industry, belongs to the technical field of feeder automation function testing, and in particular relates to a feeder automation function testing device. Background technique [0002] Feeder automation is an important part of distribution automation system, which mainly realizes the location, isolation and recovery of distribution network faults. Feeder automation is mainly divided into centralized, local recloser, intelligent distributed and other types. Due to the complex structure and various operation modes of the distribution network, the logic and parameters of different feeder automation are different. In order to ensure that feeder automation can effectively deal with distribution network faults and shorten the recovery time of distribution network faults, it is necessary to perform a functional test on feeder automation before it is put into operation. [0003] In the prior art, it is unre...
