Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings.

[0044] An automatic test system for a relay protection measurement and control device, including a host computer, a relay protection measurement and control device tester, a switch and a device under test, the host computer sends test conditions and test commands to the relay protection measurement and control device tester through the switch; The protection measurement and control device tester outputs analog quantities to the tested device according to the command, drives the binary input of the tested protective device, and reads back the binary output of the tested device to feed back to the host computer; the host computer reads from the tested protective device through the switch Take the test report, compare it, record and save the test results, where the tested device is a protection device or a measurement and control device, if the tested device is a measureme...

Abstract

The invention discloses an automatic testing system and method for a relay protection measuring and controlling device. The system and the method can automatically test the flexible configuration of a use case, and can synchronously modify the fixed value of a to-be-tested device in the testing process according to the configuration of the test use case. If the to-be-tested device is in a measured and controlled state, a relay protection monitoring and controlling device tester is used for adding amount; device information is backward read through a communication interface of the to-be-tested device and is compared with that at amount adding time; a complete close loop test is conducted on the to-be-tested monitoring and controlling device. Parameters and configuration information information are sent to the relay protection monitoring and controlling device tester through an upper computer. The communication amount and the switch amount of the to-be-tested device are increased. Communication messages are uploaded to the upper computer. A series of closed loop tests are conducted. A testing report is automatically generated. The system and method have a testing precision rectifying section, improve testing precision, are wide in application range, and have good application prospects.

Description

technical field [0001] The invention relates to the technical field of relay protection, in particular to an automatic test system and method for a relay protection measurement and control device. Background technique [0002] The static test of the relay protection device mainly includes integration test and unit test. The integration test is to test the protection function of the relay protection device. The unit test is to test the characteristics of the unit (such as a relay) inside the relay protection device. To meet the static test requirements of electrical protection devices, protection equipment manufacturers generally use testers developed by themselves or third-party commercial testers. [0003] At present, there are many kinds of third-party commercial relay protection tester products at home and abroad. The working principle of the relay protection tester is roughly the same. Generally, there are upper computer and lower computer: the upper computer is controll...
