System and method for monitoring power supply performance of nuclear power station inverter power source card

Abstract

The invention relates to a system and a method for monitoring power supply performance of a nuclear power station inverter power source card. The system comprises a front machine, a DC adjustable power source, an acquisition control device and an acquisition adaptation device, wherein a test case is received by the front machine and is analyzed to acquire a power source excitation configuration command, a sequential control command and a signal acquisition command which are then sent outside, the DC adjustable power source is used for providing a DC voltage and further outputting a power source excitation test signal according to the power source excitation configuration command, the acquisition control device is used for controlling the power source excitation test signal for accessing to the acquisition adaptation device according to the sequential control command, the acquisition adaptation device is used for inputting the conditioned power source excitation test signal to a to-be-detected inverter power source card responding pin to be a DC excitation voltage provided for the inverter power source card, and the acquisition adaptation device is used for acquiring a responding signal outputted by the to-be-detected inverter power source card according to the signal acquisition command and uploading the responding signal to the front machine. The system employs an automatic, intelligent and integrated online monitoring mode and realizes automatic tests and aging analysis on the card.

Description

technical field [0001] The invention relates to a technology for monitoring the power supply performance of an inverter power card of a nuclear power plant, and more specifically relates to a monitoring system and a monitoring method for the power supply performance of an inverter power card of a nuclear power plant. Background technique [0002] The nuclear power plant inverter power card in the related art is an important card for inverter input power regulation, and is mainly used in the inverter system of the nuclear power grid to provide working power for other cards to ensure that the chips of other cards can work normally. It is the primary link to ensure the normal operation of the inverter power module of the nuclear power plant. The mains power in the grid has fluctuations and noises and cannot be directly used for other important components of the inverter. The normal operation of the power card ensures the normal start-up of the inverter, its later operation, and...
