Abstract

The invention provides an automatic testing system and an automatic testing method for an intelligent transformer substation digital protection device. The system comprises a digital protection testing instrument and a tested digital protection device which are connected, and is characterized by also comprising an exchanger and a testing machine, the digital protection testing instrument and the tested digital protection device are connected through optical fibers, the testing machine is connected with the exchanger through a network cable, and the exchanger is respectively connected with the digital protection testing instrument and the tested digital protection device through network cables. The system and the method provided by the invention have the advantages that the problems of testing data format disunity, low testing work efficiency and excessive relying on personal ability of the technology and the mode in the digital protection device inspection process are solved, and the goals of reducing the personnel requirements, simplifying the work process and standardizing the data form are reached.

Description

technical field [0001] The invention relates to a method in the field of relay protection testing of an electric power system, in particular to an automatic testing system and method for an intelligent substation digital protection device. Background technique [0002] my country's smart substations are developing rapidly, but the detection and debugging of digital protection is still in the traditional protection debugging mode. Testers use digital protection testers to set parameters according to simulated faults, monitor the action of protection devices, verify protection functions and Whether the setting of the fixed value is correct, record the test results; or output voltage and current, check whether the sampling of the protection device is qualified. After the test is completed, manually fill in the test report. Therefore, the digital protection test method has not been standardized, the test process cannot realize automatic test, and the test report in standard form...
