Abstract

The invention relates to a safety assessment method of a TN grounding system, a control device and a storage medium. The safety assessment method of the TN grounding system comprises the following steps: determining a device fault probability corresponding to each target device in a working state, wherein the target devices are at least two of a plurality of devices; determining the system fault probability of the TN grounding system according to the equipment fault probability corresponding to each piece of equipment; the safety risk of the TN grounding system is determined according to the system fault probability, and the higher the system fault probability is, the higher the safety risk of the TN grounding system is. The safety assessment method of the TN grounding system can assess the safety risk of the TN grounding system.

Description

technical field [0001] The present application relates to the technical field of low-voltage DC power supply, in particular to a safety assessment method, control device and storage medium of a TN 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 TN grounding system. [0003] However, there are some safety risks of faults in the TN grounding system, so a method that can evaluate the safety risks of the TN grounding system is urgently needed. Contents of the invention [0004] Based on this, it is necessary to provide a safety assessment method, a control device...
