摘要
随着智能电网建设的快速发展,变电站自动化水平不断提高,对站用电源系统的可靠性和智能化程度提出了更高要求。基于此,文章基于数字化控制对变电站交直流电源系统进行设计,并对该系统进行了仿真验证。仿真验证结果表明,电源切换时间为12.3 ms,故障诊断准确率为96.2%,各项性能指标均满足设计要求,为变电站数字化转型提供了可靠保障。
With the rapid development of smart grid construction and the continuous improvement in substation's automation level,higher requirements are put forward for the reliability and intelligence of station power supply system.Based on this,this paper designs the AC/DC power supply system for substations based on digital control,and simulates and verifies the system.The simulation results show that the power switching time is 12.3 ms,the accuracy of fault diagnosis is 96.2%,and all performance indexes meet the design requirements,which provides a reliable guarantee for the digital transformation of substations.
