智能变电站直流馈线故障监测系统研究

Research on Fault Monitoring System of DC Feeder in Smart Substation

电力设施是国家经济发展的重要基础,社会发展导致用电负荷不断增加,对电网系统的可靠性要求越来越高。在电网系统中,直流馈线的故障率较高,对电网运行的稳定性有直接的影响。因此,需了解智能变电站直流系统的特点和常见故障,采用智能化技术实现对直流馈线的故障定位,快速隔离故障、及时修复并恢复供电,提升电网运行管理水平。

Power facilities are an important foundation for the country’s economic development.Social development has led to a continuous increase in power consumption,which puts higher and higher requirements on the reliability of the power grid system.In the power grid system,the DC feeder has a high failure rate,which has a direct impact on the stability of the grid operation.Therefore,it is necessary to understand the characteristics and common faults of the DC system in smart substations,adopt intelligent technology to locate faults on DC feeders,quickly isolate faults,timely repair and restore power supply,and improve the level of power grid operation and management.
