Abstract

The invention discloses an intelligent substation intelligent terminal switching-in action voltage automatic test method and system. The method comprises the steps: making a direct-current power supply introduced into a tested device, controlling closing of a switching-out contact to realize automatic switching in / out and switching of the direct-current power supply, realizing a GOOSE message output by the tested device, monitoring signal change of the GOOSE message, and judging whether a switching-in action voltage threshold of the tested device meets the standard requirement or not. According to the intelligent substation intelligent terminal switching-in action voltage automatic test method and system, the switching-in action voltage can be automatically tested, a closed-loop test can be carried out, meanwhile, a test result can be automatically stored, a detection report can be automatically generated, manual operation is avoided, the working efficiency is improved, and the test period is shortened. Meanwhile, the method is already applied to intelligent terminal device testing of the state grid and the southern grid, and through testing verification, the testing efficiency isimproved, the testing period is shortened, and the quality and operation reliability of field products are improved.

Description

technical field [0001] The invention relates to the field of automatic voltage testing of smart terminals in smart substations, in particular to a method and system for automatically testing voltages of smart terminals in smart substations. Background technique [0002] The smart terminal device of the smart substation (abbreviation: smart terminal or device under test) is a key device that collects the status of the primary equipment and controls the action of the primary equipment. At the same time, the smart terminal is also a key part of the primary and secondary linkage, and is an important component of the secondary system of the smart substation. Therefore, the quality and reliability of smart terminals directly affect the safe and stable operation of the entire smart substation. At present, in order to ensure the safety and reliability of network equipment, power users rely on professional testing agencies to strengthen the testing of smart terminals and strictly co...
