Transmitter test system and method based on real-time digital-analog simulation system

Abstract

The invention discloses a transmitter test system and method based on a real-time digital-analog simulation system. The system comprises a tested transmitter, an information feedback device and the real-time digital-analog simulation system, wherein a transmitter test simulation model is established by the real-time digital-analog simulation system according to test parameters required by the tested transmitter, and a current and / or voltage signal is outputted in a small power signal mode to the tested transmitter; in combination with an electrical signal outputted by the tested transmitter and set values of the corresponding tested parameters, whether the electrical signal at an output end of the tested transmitter meets the excessive logic test condition is detected by the information feedback device according to excessive logic test pressure plates, whether the electrical signal at the output end of the tested transmitter meets the under-logic test condition is detected by the information feedback device according to under-logic test pressure plates, and the detection result is fed back to the real-time digital-analog simulation system in the form of a contact signal; whether the test result is correct is determined by the real-time digital-analog simulation system according to the received contact signal. The system is advantaged in that test efficiency of the transmitter can be greatly improved.

Description

technical field [0001] The invention relates to a transmitter testing system and method based on a real-time digital simulation system, belonging to the technical field of power systems. Background technique [0002] Transmitters are widely used in power systems, especially in power plants. Voltage transmitters and current transmitters that respond to excitation voltage and excitation current are more widely used, but there is a lack of effective means for testing transmitters, especially in power plants. The transient characteristic test of the transmitter is difficult to achieve with a static tester, such as the ripple characteristic response of the harmonic content, the excitation system failure or the sudden drop of the excitation voltage at the abnormal time, and the sudden rise of the excitation voltage during the forced excitation process etc. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, p...
