Abstract

The invention relates to a safety assessment method of an IT grounding system, a control device and a storage medium. The method is applied to an IT grounding system, the IT grounding system comprises a plurality of devices connected to the same DC bus, and the IT grounding system safety evaluation method comprises the steps of determining a first fault probability corresponding to each target device in a working state, the target devices being at least two of the plurality of devices; determining the system fault probability of the IT grounding system according to the first fault probability corresponding to each target device; the safety risk of the IT grounding system is determined according to the system fault probability, and the lower the system fault probability is, the lower the safety risk of the IT grounding system is. The safety assessment method of the IT grounding system can assess the safety risk of the IT grounding system.

Description

technical field [0001] The present application relates to the technical field of civil power supply, in particular to a method, device, equipment and storage medium for safety assessment of an IT grounding system. Background technique [0002] With the development of power electronics technology and the continuous access of new energy sources (such as photovoltaics and energy storage), a low-voltage DC power supply system has emerged in the field of civil power supply. The low-voltage DC power supply system has the characteristics of safety, reliability and economy. The common low-voltage DC power supply system in the current civilian 220V AC system is the IT grounding system. [0003] However, there are some safety risks of faults in the IT grounding system, so there is an urgent need for a means to assess the safety risks of the IT grounding system. Contents of the invention [0004] Based on this, it is necessary to provide a security assessment method, device, equipme...
