Embedded test method for in-situ relay protection with switchable protection function

Abstract

The disclosure relates to an in-situ relay protection embedded test method with switchable protection functions. The method includes: constructing an in-situ protection model of a substation according to the distribution network structure; importing the SCD file of the substation into the model for processing, and determining the operation configuration files and prediction results of a plurality of in-situ relay protection devices in the substation; Download the in-situ protection model and operation configuration file to the in-situ relay protection test device to generate multiple simulated in-situ relay protection devices; carry out functional tests on the target simulated in-situ relay protection device, and obtain Test results; according to the test results and prediction results, a test report of the in-situ relay protection device is generated. The embodiments of the present disclosure can quickly perform device and system fault test verification in real time without being limited by the site and test environment, improve the response speed, data accuracy, and adaptability of the device, and can ensure the safe, stable and reliable operation of the distribution network.

Description

technical field [0001] The disclosure relates to the technical field of electric power engineering, in particular to an embedded test method for in-situ relay protection with switchable protection functions. Background technique [0002] With the development of computer and communication technology, various types of digital on-site relay protection devices have emerged as the times require, which has greatly improved the safe and stable operation level of the power system, but the functions, algorithms and communication methods of the protection devices are different for each The development mode of separate design of hardware and software for type protection is inefficient, difficult to maintain, and not suitable for the development of new situations. In this case, the development model based on common platform technology has been used, which not only improves the efficiency of development, but also shortens the development cycle of new products. Practice has proved that t...
