Abstract

The invention discloses a power distribution automation three-remote function closed-loop test system and method. The system comprises a three-remote test workstation, a three-remote tester, a power distribution automation terminal and a power distribution network automation master station, wherein the three-remote test workstation is used for acquiring three-remote configuration parameter information from the power distribution network automation master station and transmitting generated three-remote test case parameter information to the three-remote tester, the three-remote tester is used for transmitting on-off state information and analog quantity to the power distribution automation terminal, the power distribution automation terminal generates SOE (sequence of event) information after operation, transmits the SOE information to the power distribution network automation master station, the power distribution network automation master station transmits the SOE information to the three-remote test workstation, the power distribution automation terminal transmits the SOE information to the three-remote tester, the three-remote tester transmits the SOE information to the three-remote test workstation, and finally, the three-remote test workstation generates a three-remote test report. Technical requirements for on-site constructors are reduced, on-site installation and commissioning workload is greatly relieved, and maintenance efficiency is improved.

Description

technical field [0001] The invention relates to distribution network testing, in particular to a distribution automation three-remote function closed-loop testing system and method. Background technique [0002] The smooth implementation of the distribution automation system depends on a large number of distribution automation terminals installed on site, which mainly have the functions of analog quantity acquisition, digital quantity acquisition and control quantity output, referred to as telemetry, remote signaling and remote control (three remote) functions. Whether the functions and performance of the three remotes of the distribution automation terminal can meet the technical standards is the key to the success of the distribution automation project. Before the distribution automation system is officially put into operation, all distribution automation terminals need to be tested on the network. After that, random inspections will be carried out during the installation ...
