Radiation emission test system and radiation emission test method

Abstract

The invention provides a radiation emission test system and a radiation emission test method, and relates to the technical field of electromagnetic compatibility test. The radiation emission test system includes a control device, a signal source, a receiver, a radio communication tester, a radiofrequency signal processor, a filter, a radiofrequency cable, a general purpose interface bus (GIPB) cable, an electric wave darkroom, a preamplifier, a measuring antenna, an antenna tower, an antenna cable, a test rotary table, a radio communication tester antenna and a pre-embedded cable. The preamplifier, the measuring antenna, the antenna tower, the test rotary table and the radio communication tester antenna are arranged in the electric wave darkroom; and the pre-embedded cable is embedded in the wall of the electric wave darkroom or under the ground. By establishing a mathematical model of the electric field intensity for the radiation emission test system and analyzing various uncertain source components of the radiation emission test system, the expanded uncertainty of the radiation emission test system can be determined so that a test result can be revised, and the accuracy and the reliability of a final test result can be raised.

Description

technical field [0001] The present invention relates to the technical field of electromagnetic compatibility testing, in particular to a radiation emission testing system and method. Background technique [0002] In the power field, it is usually necessary to conduct electromagnetic compatibility tests on smart substation equipment to determine whether the smart substation equipment can operate normally in a complex electromagnetic environment. [0003] At present, the electromagnetic compatibility test for smart substation equipment must build a radiation test system in accordance with the corresponding national standards. The specific technical content involved is as follows: [0004] 1. When the device under test is a non-wireless communication device, the radiation emission test system needs to be designed according to the standard GB9254-2008, and when the device under test is a wireless communication device, the radiation emission test system needs to be designed accor...

AI Technical Summary

Problems solved by technology

[0010] At present, the radiation emission test system built for the electromagnetic compatibility test of smart substation equipment is uneven, and the influence factors of the radiation emission test system itself on the uncertainty of the electromagnetic compatibility test are not considered, and the accuracy of the final test results is also low. not high enough
