Research and practice on the scheme of automatic testing of power protection device security

In order to improve production efficiency and reduce production costs of relay protection device, according to the test process and the existing technical conditions, this paper proposes an efficient automatic test scheme. Based on the existing protection device test cases and the computer technology, it sums up the automatic test categories; based on the basic idea about reusable test cases, it proposes the compiling method of reusable test cases using the mapping mode of tagged word. It realizes the automation for the functional test of the protection device with the cooperation of tester and IO card. Implementation results show that the scheme proposed greatly improves the test efficiency and realizes the basic needs of repetitive work automation processing. At the same time, it automatically generates test reports for the filing management and improves the electronic level of management and the management quality.
