DESIGN AND CONSTRUCTION MONITORING SYSTEM PARAMETERS OF POWER QUALITY

After providing power electronic devices, power quality in the industries more and more was considered. The defined parameters and new standards for power quality, displaying and monitoring of these parameters among the topics are important and significant. The project design and construction of an example of a data acquisition system (data logger) is explained. Firstly, power quality and parameters will be introduced to it. Then the algorithm for finding the harmonic signal analysis is discussed. In this paper, a system is designed that as acceptable quality problems can be identified and measured by sensors Hall effect for sample voltages and current systems. Data acquisition for data transfers to computer and two examples of software by the Lab VIEW and C is designed and used for signal analysis. This system detects voltage and current harmonics up to 121th componentʹs and flicker on voltage detection; diagnosis and records the voltage drop as well as determines the abnormal voltage and current wave form of the harmonics in the power network.
