Abstract：A simple type of electrical appliance category and working status recognition device is designed to address the low testing accuracyof the market electrical appliance analysis and detection devices.The active power calculationand eigenvalue extraction judgment methodsbased on Fourieranalysisareadopted，combined with positioning recognition algorithms，is proposedto identify the typeand number ofconnected electricalappliances. Firstly，theactive powerand powerfactoroftheelectrical appliancearecalculated，andthentheharmonic powerof eachorderisobtainedthroughFourier analysis.Finally，byusing fourparameters includingactivepoweras similarityindicators，the templatematchingalgorithmisused to learnandrecognizethecategoriesand statesof electricalappliances.After testing，thedevicehasalearning functionandcanaccurately identifythestatusand category of electrical appliances.Its testing accuracy forthe typesandnumbers of electrical appliances reaches （204号 100% ，indicating certain application value.

Key words ： electrical appliance analysis;； Fourier analysis；active power; location recognition method; similarity

0引言

目前，实际应用中的校园供电系统基本采用功率判断模式，通过监测功率简单判断用户的供电情况，该方法存在诸多缺点，不能实现电力资源的合理有效利用。（剩余4461字）
