System and method for testing performance of alternating current sensitive components of inversion control interface card of inverter

Abstract

The invention relates to a system and a method for testing the performance of alternating current sensitive components of an inversion control interface card of an inverter. The test system comprises a pre-control device, a signal generation device, a collection control device and a collection adaptation device; the pre-control device receives different test samples and respectively analyzes the test samples to different control commands; the signal generation device receives a signal excitation command and sends a test signal to the collection control device; the collection control device receives a test control command and the test signal and sends the test signal to the collection adaptation device according to the test control command; and the collection adaptation device receives the test signal, conditions the test signal and outputs the test signal to the inversion control interface card of the inverter to test the performance of the alternating current sensitive components therein. The test system and method provided by the invention are used for solving the problem that the interior sensitive components cannot be directly measured and automatically carrying out steps that require a lot of manual operations to liberate the testing personnel.

Description

technical field [0001] The invention relates to the on-line monitoring technology of power equipment in nuclear power plants, and more specifically relates to a performance testing system and method for AC sensitive components of an inverter inverter control interface card. Background technique [0002] Now nuclear power plants generally use uninterruptible power supply to ensure the safe and stable operation of the power station. As a very important part of the uninterruptible power supply, the inverter card is an important card to ensure the normal operation of the inverter and rectifier control system of the nuclear power plant. Different types Inverter cards are available for different power supply systems. [0003] The inverter inverter control interface card is an important card in the LNG inverter system. It has the function of alarming the abnormal DC bus voltage, collecting signals and providing power output for other cards in the system. The most critical sensitiv...

AI Technical Summary

Problems solved by technology

[0004] At present, there is no targeted research on the inverter cards of nuclear power plants in China. Nuclear power plants generally use manual inspection of the relevant cabinets of the operating system and identification of the appearance of the cards to confirm whether the inverter phase comparison card is correct or not. working normally

Manual testing cannot automatically or batch power-on test and analysis of old cards, and it lacks test and analysis of sensitive components inside the cards. Moreover, the wiring of the cards is complicated during the test, which requires high operating requirements for the staff, and even some personal danger
