Research On The Intelligent Management System Of Electric Energy Of Dormitory

In the paper, the problems of the power quality in modern social are summarized, a new mixed signal arithmetic is introduced to aiming at the power quality problems with extensive influence, and the arithmetic is identified by expert system. Combining with the reality of the power management in students' dormitory, the author design the thought about power intelligent manager.First, the power quality problems are introduced widely, as well as the demand of the society and current situation of management at present, the power quality phenomenon and domestic and international power quality level are summarized. And the harmless brought by quality problems is introduced.It is identified by expert system. Based on comparing and analyzing NN, nearest neighbors, fuzzy decision, and expert system, according to the characters about analyse of power quality signal fault, the method rule-based expert system is analysed, and the method's characters are expanding , amending easily and high identifying rate etc.Combined with the facts about the power management in the students' apartment, a kind of Phase-angle method is introduced in the paper, compared with other arithmetic, the realization about load distinguishing system is put forward. After introducing the wavelet theory simply, the application of the Dmeyer wavelet function in load distinguishing system is illustrated.In the end of the paper, the measure for electrical parameters and recognizing the electrical appliances are summarized, and the author design the thought about power intelligent manager.
