Problems solved by technology

However, in the operation of distribution automation, it is found that there are still problems such as system instability, poor practicality, high equipment defect rate, and low fault location accuracy.
However, the existing automated test technology for feeders generally uses multiple relays to complete simple functional inspections with the support of terminals, master stations and other equipment and equipment suppliers, but the functional inspections in this way ignore fault information and interference data. , the test accuracy is biased, and it is inefficient

Abstract

The invention discloses a feeder automation test system which comprises a control unit, a power amplifier and an interference generator. The control unit is used for completing analog quantity output amplitude and angle control, analog quantity output recovery correction and communication control, and carrying out feeder automation testing; and the power amplifier is used for amplifying a weak voltage signal into an alternating current signal and an alternating voltage signal and outputting the alternating current signal and the alternating voltage signal through the analog quantity output module, and the interference generator analyzes and interferes the signal input into the control unit through the digital quantity input module and sends out a control signal of the control unit through the communication control module. Analog quantity output amplitude and angle control, analog quantity output recovery correction and communication control are completed through the control unit, comprehensive and wide feeder automation testing is carried out, fault information and interference data are input through the interference generator, real-time parameter configuration and operation state monitoring are achieved, and a testing result is more accurate.

Description

technical field [0001] The invention relates to the technical field of feeder testing, in particular to a feeder automatic testing system. Background technique [0002] The construction of distribution automation system is being further developed, and has achieved good construction and application results. However, in the operation of distribution automation, it is found that there are still problems such as system instability, poor practicality, high equipment defect rate, and low fault location accuracy. However, the existing automated test technology for feeders generally uses multiple relays to complete simple functional inspections with the support of terminals, master stations and other equipment and equipment suppliers, but the functional inspections in this way ignore fault information and interference data. , the test accuracy is biased and inefficient. Contents of the invention [0003] The purpose of this section is to outline some aspects of embodiments of th...
