Prediction and Analysis of Grounding Fault in Direct Current System of Smart Substation
In the intelligent substation system,the direct current system is the core structure and an important support for relay protection,lighting and other work.In practice,once a grounding fault occurs in a direct current system,it is easy to induce equipment protection misoperation,leading to various faults in the power grid.The article briefly elaborates on the relevant content of grounding faults in the direct current system of intelligent substations by consulting relevant literature,comprehensively analyzes and studies the prediction strategy of grounding faults in the direct current system of intelligent substations,and obtains and verifies the feasibility and application value of the prediction method.
