Distribution-automation distributed type FA (feeder automation) linkage test method and system

Abstract

The invention relates to a distribution-automation distributed type FA (feeder automation) linkage test method. The method comprises the following steps of enabling a main station to send configuration parameters of a relay protection tester, and enabling the relay protection tester to send voltage and current signals to a distributed type FA terminal to be collected; starting to test, and enabling the distributed type FA terminal to judge the faults after the load change of the abnormal current is detected, and report a telemetering and telesignaling value to the main station; after the main station receives the abnormal telemetering and telesignaling value, controlling the relay protection tester to send a remote control signal to a switch simulation device which is used for simulating a switch on a column; and after the switch simulation device acts according to the received remote control signal, feeding the processed information back to the main station by the distributed FA terminal. The invention also discloses a distribution-automation distributed type FA linkage test system. The method and the system have the advantage that the power off of a line is not required, the fault simulation signal is directly provided for the FA equipment, the influence on the safe and normal running of primary equipment in the debugging process of the distribution-automation system is avoided, and the test process is more concise and quicker.

Description

technical field [0001] The invention relates to the field of distribution network testing, in particular to a distribution automation distributed FA linkage testing method and system. Background technique [0002] In distribution automation equipment, the test of terminal equipment such as distributed FA (Feeder Automation-feeder automation) is a crucial technical task with a huge workload. After the installation and commissioning of the intelligent distributed FA project is completed, the fault handling function of the FA needs to be further tested to verify the correctness of the configuration parameters. The current general test method is: power off the primary line of the FA power supply loop, load the simulated fault current to the corresponding measurement point with the relay protection device, and synchronize the personnel at each point with the walkie-talkie when the fault current is loaded. The advantage of this traditional method is that it can directly operate t...

But the disadvantages are also obvious. During the test process, the line needs to be powered off, and the loading current needs to be synchronized by manual shouting. It is difficult to guarantee the success rate of the one-time test, and there is no intuitive display of the test process.
