The power supply fault simulation device comprises an upper computer, an excitation power supply and fault injection equipment. A main power supply for supplying power to a power supply network and the excitation power supply are connected with the power supply network through the fault injection equipment. The excitation power supply and the fault injection equipment are connected with the upper computer. The upper computer transmits the voltage parameter to the excitation power supply. The upper computer transmits the connection parameter to the fault injection equipment. The excitation power supply outputs voltage according to the voltage parameter. The fault injection equipment controls the connection between the excitation power supply and the power supply network according to the connection parameter and controls the connection between the main power supply and the power supply network according to the connection parameter. The voltage is outputted according to the voltage parameter through the excitation power supply, and the fault injection equipment controls the connection between the excitation power supply and the power supply network according to the connection parameter and simulates the possible fault in the power supply process through cooperation with the main power supply so that the reliability of the power supply network under various faults can be detected.

Description

technical field [0001] The invention relates to the field of power supply, in particular to a power supply failure simulation device and a power supply failure simulation method. Background technique [0002] An important criterion for determining the stability of the power supply network is the fault tolerance of the power supply network. The fault tolerance of the power supply network needs to be detected by testing the power supply network. [0003] The existing test method for the power supply network is to perform a stress test on the power supply network, that is, supply power at a fixed voltage for a fixed time, and test the stability of the power supply system under the condition of long-term power supply. [0004] As the complexity of the power supply network increases, different faults will occur in the power supply network during use, and with the improvement of the performance requirements of the power supply network, the power supply network is required to be ab...
