摘　　要：为获得微电网中各分布式电源的各项电能质量参数,结合虚拟仪器技术、数据库技术与网络通信技术开发了微电网电能质量监测系统。该监测系统包括前置机系统、服务器系统及网络通信系统,实现了微电网内分布式电源电能质量的同步监测和数据的有效管理。最后探讨了不同电能质量参数的测量计算方法,并设计了暂态电能监测模块。试验测试证明,该监测系统测量精度较高,稳定性好,网络传输时无数据丢失。To get power quality characteristics of distributed generations in microgrid, the paper establishes power quality monitoring system based on virtual instrument, database and network communication technology. The monitoring system consists of front-end system, server system and network communication system, and also can synchronously monitor the power quality of the distributed generations in microgrid and manage amounts of data effectively. Moreover, the paper explores the calculation methods of different power quality parameters, and designs the transient power monitoring module. Finally, the test shows that the monitoring system mentioned above is of high measurement accuracy and reliability, and avoids data loss in network transmission.
