摘要
在智能变电站系统中,直流系统是核心结构,也是继电保护、照明等工作的重要支撑。在实践中,直流系统一旦出现接地故障,就很容易诱发设备保护误动作,导致电网出现多种故障。文章通过查阅相关文献,简要阐述了智能变电站直流系统接地故障的相关内容,综合分析并研究智能变电站直流系统接地故障的预测策略,得出并验证预测方法具有一定的可行性与应用价值。
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.
