Problems solved by technology

Because it is necessary to test the compatibility and performance between the 2M optical interface board and the protection equipment of any manufacturer, using the existing test method to continuously replace the protection equipment in the test system, the test efficiency is low, and a single test cannot guarantee the consistency of the test environment sex, low accuracy
[0010] To sum up, in the prior art, there is still a lack of an effective solution to the problem of low efficiency and accuracy of the test method for the compatibility and performance between the 2M optical interface board and the protection equipment of any manufacturer.

Abstract

The invention relates to a joint test system and method based on a 2M optical interface protection device. The system is based on a pair of transmission devices configured with 2M optical interface boards in communication connection. The system is characterized by comprising point-to-point test longitudinal channels which are respectively connected with 2M optical interface boards of transmissiondevices at two ends and are sequentially connected with a real-time digital simulation system and a power amplifier, and a plurality of corresponding protection devices are sequentially connected in the two test longitudinal channels in parallel for joint test. According to the invention, the efficiency and accuracy of the test system of the 2M optical interface protection device are effectively improved, and the method has a great practical value for the next step of line performance test and popularization.

Description

technical field [0001] The invention belongs to the technical field of substation relay protection, and in particular relates to a joint test system and method based on a 2M optical interface protection device. Background technique [0002] At present, the scale of the power system is increasing with the development of the economy, and the structure is becoming more and more complex. The operation must be safe and reliable, with high power quality and good economy. However, due to the influence of natural conditions, equipment and artificial factors, various failures and abnormal operating conditions may occur. The most common and most harmful faults are various types of short circuits. Faults or abnormal operating conditions may lead to accidents if they are not dealt with in a timely manner. In order to deal with faults and abnormal operating conditions correctly in time and avoid accidents, relay protection is produced. Relay protection mainly uses the change of elect...
