Abstract

The invention provides a testing system of a feeder line automatic system. The testing system comprises a plurality of sub-modules and a bus controller, wherein the transmission of a communication signal is realized between the bus controller and each sub-module through a first type of connecting line, the transmission of a control signal is realized between the bus controller and each sub-module through a second type of connecting line, and each sub-module is at least used for responding to the communication signal transmitted by the first type of connecting line, and generating and outputting at least one of an alternating current signal for one path of testing and an alternating current voltage signal for one path of testing according to the communication signal; each sub-module is at least used for responding to the control signal transmitted by the second type of connecting line, and performing running and state feedback according to the control signal.

Description

technical field [0001] The invention relates to the field of feeder automation, in particular to a test system of a feeder automation system. Background technique [0002] In the power system, the power companies all over the world generally use the FA (Feeder Automation) system, that is, the feeder automation system. When a fault occurs at a certain point in the distribution network, it will cause power outages in the same power supply area, and in severe cases, it will lead to large-scale power outages. At this time, the FA system should remove the faulty area as soon as possible, and then restore power to the non-faulty area. [0003] Before the FA system is actually put into application, various functional tests must be carried out. The test equipment is required to independently output 8-channel AC current signal and 8-channel AC voltage signal. It is required that the amplitude and phase of these signals can be independently controlled and electrically isolated from ...
