Abstract

The invention relates to an intelligent substation relay protection device intelligent test method, including the following steps: a device template editing module performing editing according to a test requirement of a device under test to generate a device test template; and an automatic test module receives the device test template according to user selection, executes testing of test items in the device test template, and writes test data in a report template to form a test report. The system includes a device template editing module and an automatic test module. The intelligent substation relay protection device intelligent test method provided by the invention solves the problems that in the process of inspecting a digital protection device, technologies and modes are overdependent on personal ability, test work efficiency is low, and test data formats are nonuniform, a normalized, standardized and efficient automatic inspection method aiming at a digital protection device under test is provided, and the purposes of lowering personnel requirements, simplifying a working process and normalizing the data format are achieved.

Description

technical field [0001] The invention relates to a system and a method in the field of relay protection testing of an intelligent substation in a power system, in particular to an intelligent testing system and method for a relay protection device of an intelligent substation. Background technique [0002] my country's smart substations are developing rapidly, but the detection and debugging of intelligent protection devices still remain in the traditional protection debugging mode. Testers use digital protection testers to set parameters according to simulated faults, monitor the action of protection devices, and verify protection. Check whether the function and setting are correct, operate the protection panel at the same time, check the protection action information, and 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 digit...
