Test method for dry contact action delay of intelligent terminal equipment

Abstract

A method for testing the action delay of a dry contact of an energy terminal device, comprising the following steps: (1) associating the site to which the smart terminal belongs with the SCD file to which the site belongs; (2) analyzing the SCD file to which the site belongs, and analyzing the Form a whole station IED list and save it in the relational database; (3) Select the intelligent terminal to be tested from the IED list; (4) Connect the dry contact of the intelligent terminal to be tested with the test equipment; (5) Set the test delay (6) Name the dry contact under test; (7) Obtain the input virtual terminal list of the intelligent terminal; (8) Determine the mapping relationship between the dry contact and the virtual terminal; (9) Perform an action delay test on the dry contact; (10) Display the mapping relationship between dry contacts and virtual terminals and the test results of each virtual terminal. The invention avoids extremely serious power system accidents caused by the fact that the action delay of the dry contact fails to meet the technical requirements.

Description

technical field [0001] The invention relates to a dry contact action test method, in particular to a dry contact action delay test method for intelligent terminal equipment, which belongs to the technical field of power system automation. Background technique [0002] At present, many electronic devices used in the power industry are controlled and operated through the opening and closing of dry contacts, and they all receive network messages of the 61850 protocol to drive dry contact actions. A key indicator of electronic equipment used in the power industry is the delay of dry contact action. The delay of dry contact action refers to the time difference between the moment when the electronic equipment receives the instruction and the moment of action of the dry contact. Time dispersion refers to the multiple measurements of the action delay of the dry contact. The difference in the results reflects the stability of the dry contact action delay. Therefore, when the electro...
