英文摘要：

In order to adapt to the development requirements of internetized and intelligent quality monitoring devices, this article designed a network electrical energy quality monitoring device based on TMS320F28335 DSP, which can be used to online monitor the quality of three-phase power supply and distribution system. The t＇unetion design, hardware design, software design and Modbus communication realization were given. The practical running results prove that the device can realize the functions of monitoring and analyzing quality indices, accomplish all the communication tasks in real time, and also gives both consideration to the performance and the cost.
