隨著電力系統(tǒng)中大量非線性負荷的出現(xiàn)，電能質(zhì)量不斷惡化。本文在研究電力系統(tǒng)電
能質(zhì)量指標的基礎上，針對農(nóng)村電網(wǎng)的特點，設計了一種能夠監(jiān)測和管理電能質(zhì)量指標的新型的電能質(zhì)量監(jiān)測系統(tǒng)，并詳細介紹了系統(tǒng)總體設計、監(jiān)測終端設計與實現(xiàn)的方法。

Design and implementation of power quality monitoring system for rural power grid
HUANG Xiao-hong1,2 （1, Training center of Guangdong Industry Technical College, Guangzhou Guangdong, China, 510300; 2, Department of Automation, South China University of Technology, Guangzhou Guangdong, China, 510640） Abstract: With the emergency of much non-linear load in power system, the power quality has been deteriorating. Based on an analysis of quality indexes for power system, a kind of integrated supervisor which can measure and analyze power quality issues is proposed. The total architecture design, terminal design and software design and their implementation are introduced in detail.
