DAQ and Power Quality Analysis of Electrical Parameters in Romanian Schools

In Romania, schools are some of the largest power consumers, accounting for about 25% of public power-consuming institutions. Considering the common energy profile, which represents the vast majority of consumer cases of the same type existing in classrooms, in laboratories, in heating and lighting systems, the monitoring and analysis of electrical energy parameters, may be extremely important. Based on the data obtained from the data acquisition system, becomes possible to develop advanced algorithms for modeling a school-type consumer and finally to improve the power quality. Also, the energy parameters are compared to those established by international standards to do the power quality analysis. The presentation of the data acquisition system, the results obtained and the analysis of the electrical energy parameters for an example of a school-type consumer are the basic topics of this article.
