基于Labview的电能质量检测设计 【摘 要】 进入二十一世纪以来，科学技术以及社会经济迅猛发展进步，城镇居民的日常生活水平也不断提升，现代化的工厂与城镇居民对电能的不单单总量方面越来越大，同时对电能质量方面的要求也越来越多。电能作为截至目前，应用最为广泛的现代化能源，电能的运行质量将会对工业的正常生产，以及城镇居民的日常生活水平产生重大的影响，这也是电力有关部门以 及电力使用者继续处理的一个能源问题。本文目标是研制出一套基于 Labview 的电能质量在线检测系统，研究多种电能质量指标检测分析的原理，在对已有的电能质量检查方式的基础之上，选用 Labview 操作软件完成对电能质量里电流、频率、振幅以及运行稳定性等方面，进行实时检测记录，同时在线处理计算及结果，所有的设计都在在Labview环境下实现。 关键词：电能质量；在线检测；Labview  【Abstract】 With?the?rapid?change?of?technology?of?contemporary?society?and?development?of?economy,?the?living?conditions?of?the?residents?has?been?generally?improved,?demand?of?modern?factories?and?urban?and?rural?residents?for?power?has?become?more?and?more?big?and?the?requirement?for?power?quality?has?become?more?and?more?strict.?As?the?most?widely?used?modern?energy,?power?quality?issue?has?a?direct?impact?on?normal?industrial?development?and?the?safety?and?living?standard?of?the?residents,?which?is?a?problem?the?electric?power?department?and?the?users?must?take?seriously.?The?objective?of?this?paper?is?to?develop?a?set?of?On-line?detection?system?based?on?power?quality?of?Labview;?it?studies?on?relevant?theories?of?the?measurement?and?analysis?of?the?index?of?power?quality.?Based?on?the?method?of?power?quality?detection,?it?adopts?Labview?software?to?realize?real?time?detection?of?current,?voltage,?frequency,?power?harmonic,?three-phase?voltage?unbalance,?voltage?pulsation?and?flickering?in?power?quality,?and?analyzes,?calculates?and?gets?the?results?online;?All?designs?are?implemented?under?Labview?environment.
