基于智能开关的配网电能质量监测及其分布式治理技术研究

介绍了一种多功能的智能开关设备,其将线路通断、数据采集、数据识别、数据发送等功能进行集成融合,并配置边缘计算网关,可用于实现配电线路节点的智能化。基于该智能开关,建设含10 kV配变、框架断路器、入户断路器/开关的三级结点智能化配电网络,并通过对用电数据的监测和分析,重点评估台区用电质量,包括功率因数和总谐波畸变率。以具体配电台区为研究对象,验证了电能质量监测与分布式治理方法。

Research on Power Quality Monitoring and Distributed Governance Technology of Distribution Network Based on Intelligent Switch

This paper introduces a multi-functional intelligent switchgear,which integrates the functions of line on-off,data acquisition,data recognition,data transmission,and configures an edge computing gateway,which can be used to realize the intellectualization of distribution line nodes.Based on the intelligent switch,a three-level node intelligent distribution network including 10 kV distribution transformer,frame circuit breaker and in door circuit breaker/switch is constructed.Through the monitoring and analysis of power consumption data,the power consumption quality of substation area is mainly evaluated,including power factor and total harmonic distortion rate.Taking the specific distribution area as the research object,the method of power quality monitoring and distributed governance is verified.
