摘要:
基于CPS（信息物理系统)理论，对地铁供电智能运维系统中设备的三相电压进行监测，并实现三相电压不平衡度的实时计算。将专家经验法及深度残差收缩网络法相结合得到合理阈值，并提出了三相电压不平衡度的预警方案。在此基础上，对三相电压不平衡度的单指标评估模式进行优化，提出了基于熵值法的电能质量多指标评分模型。将三相电压不平衡度阈值优化的方法应用于电能质量阈值确定,最终提供了阈值预警、评分矩阵映射预警、预警等级迁移预警3个层次的预警方案。
Abstracts:
Based on the Cyber Physical System (CPS) theory, the three-phase voltage of the equipment in the intelligent operation and maintenance system of metro power supply is monitored, and real-time calculation of three-phase voltage unbalance is realized. A reasonable threshold is obtained by combining the expert experience method and the deep residual shrinkage network method, and an early-warning scheme of three-phase voltage unbalance is proposed. On this basis, the single-index evaluation model of three-phase voltage unbalance is optimized, and a multi-index scoring model of power quality based on entropy method is proposed. The three-phase voltage unbalance threshold optimization method is applied to the determination of power quality threshold. Finally, three levels of early-warning schemes are provided: threshold early-warning, scoring matrix mapping early-warning, and early-warning level migration early-warning.
