Power quality (PQ), acquisition card, measurement system (MS), measurement of harmonics, measurement of flickers In this paper is presented an approach in development of measurement system (MS) for analyzing the power quality (PQ). The main aim of this paper is to present procedures of PQ measurements according to the strictest norms and standards and to develop a system for measuring specific indicators of PQ. The developed MS is implemented on several examples. In this paper is presented an example of implementing the MS in analyzing the loads mode of an apartment with appliances of new generation (energyefficient appliances). In the paper is also explored the problem of implementation of universal acquisition cards for their application in analyzing PQ. The main focus of conclusions in this paper is comparison of present and future systems for monitoring the PQ. |
