基于LabVIEW的微网电能质量监测评估系统

针对现阶段微网电能质量实时监测和综合评估系统软件缺失的问题,对微网电能质量合理的综合评估方法进行了研究,探讨了一种基于LabVIEW编程平台的电能质量监测评估系统的设计方案.首先,提出了一种基于改进的层次分析法（AHP）和灰色理论相结合的微网电能质量综合评估方法.然后,利用LabVIEW和Matlab Script语言混合编程优势,通过LabVIEW平台开发了一套可实现微网电能质量实时监测、合理评估和综合管理的智能系统,并利用学校的微网模型对该系统进行了测试.研究结果表明,该系统能实时监测微网各项电能质量指标,具有报警录波功能,同时可对微网的综合电能质量作出合理的评估,可生成报表以汇总微网各单项电能质量指标和综合电能质量评价结果,具有良好的工程化应用前景.

Power quality monitoring and evaluation system for micro-grid based on LabVIEW

Aiming at lack of the power quality real-time monitoring and the software of the comprehensive evaluation system for micro-grid,a reasonable method of power quality comprehensive evaluation was studied,a system for power quality monitoring and comprehensive evaluation based on LabVIEW was designed.Firstly,based on an analytic hierarchy process （AHP） method and grey theory,the power quality evaluation system was proposed.Then,based on LabVIEW,the system software for power quality monitoring,the comprehensive evaluation and intelligent management for micro-grid were developed by using hybrid programming method with LabVIEW and Matlab Script programming languages.It was simulated by the micro-grid model.The results indicate that the system software can be real-time monitoring of microgrid,recorded wave function with alarm and make a reasonable assessment of the integrated micro-grid power quality,generate a summary report for the results.A good prospect for engineering application in micro-grid projects is shown.
