Design of distributed power quality monitoring system for distribution house

The construction of smart grid puts forward higher requirements for power quality. As the key node of power distribution system, power quality monitoring of distribution room has always been the weak link of power operation and maintenance. This paper presents a distributed power quality monitoring system for distribution room, which includes hardware design and software design. It has the functions of acquisition, analysis, display and communication. It can complete distributed power quality monitoring for multiple outgoing branches of distribution room. The application of this system can provide data support for power quality analysis and management of low-voltage distribution system.
