Embodiment Construction

[0008] The present invention will be further described below in conjunction with accompanying drawing:

[0009] As shown in the figure, when testing smart substation equipment, the high-voltage side and low-voltage side of the transformer S are respectively equipped with a special tester 1 and a special tester 2, and the current output and voltage output of the two special testers are connected to each side The current input terminal of the intelligent terminal is connected to the voltage input terminal; the switch input and output terminals of each special tester are respectively connected to the merging unit on each side; the optical fiber communication terminals of each special tester are respectively connected to the intelligent terminal and the The spare optical fiber for the communication of the transformer protection device is connected to the computer at the transformer protection device. When testing, connect the timing terminal of each special tester to the timing si...

Abstract

The invention discloses a testing method of intelligent transformer station network digitization equipment, which is characterized by comprising the steps that a high voltage side and a low voltage side of a transformer are connected with special testers respectively; optical fiber communication ends of the special tester are connected into intelligent terminals and a standby optical fiber communicated with a transformer protection device; and the standby optical fiber is connected into a computer on one side of the transformer protection device. According to the testing method, more than two special testers, the computer, and the standby optical fiber of an intelligent transformer station are utilized, so that all-project non-intervention automatic testing of an intelligent terminal-merging unit-protection device function of the intelligent transformer station can be achieved.

Description

technical field [0001] The invention relates to a test and analysis method, in particular to a test method for digital equipment of an intelligent substation network. Background technique [0002] The smart substation is based on networking and digitalization, and adopts the IEC61850 system architecture to realize the interconnection of IED equipment. In the acceptance, operation and maintenance of smart substations, for protection devices that need to use multiple sets of AC (current, voltage), especially when the locations of each AC are far apart, the existing test equipment cannot The overall protection test is carried out using analog quantities, but only single-device tests can be performed on each device, that is, the functions of smart terminals, merging units, protection devices, etc. are tested separately, the cooperation between these devices and the smart terminal There is no comprehensive, effective and intuitive test method for the correctness of secondary sys...
