A New Methodology For On-Line Power Quality Asseessment
The Renewable Energies and Power Quality Journal (RE&PQJ)
The development of new methods for real time detection and evaluation of voltage events in the distribution systems is of great importance in order to prevent the impact of these disturbances on customer equipment and to evaluate the economics of power quality improvement alternatives. The main objective of this work is to introduce a new methodology of advanced power quality assessment. The introduced system is implemented using powerful software algorithms to construct a system for real time
... stem for real time detection and identification of different types of power quality disturbances. A number of disturbance events have been simulated for further processing and analysis The introduced system detects accurately any power quality disturbance event and introduces new indicative factors estimating the performance of any supply system subjected to different categories of disturbance events. Moreover, a new mitigation technique through constructing feedback correction signals for disturbance compensation is suggested. For complete automatic on-line monitoring, detection and identification system, a hardware device for disturbance simulation, and a data acquisition card for real time monitoring system were under construction.
