The nature of electric force and unsettling influences happened in power signal has gotten a significant issue between the providers & clients. For enhancing quality constant checking is required that being conveyed at client's destinations. Thusly, recognition “POWER QUALITY” aggravations, appropriate characterization D profoundly attractive. location appropriation frameworks are errands f...
It makes the topology of distribution network more complex to contain a lot of distribution generations (DGs) in it. For this reason, a fault location approach suitable to the distribution network containing DGs is proposed. Firstly, according to the results of power flow calculation, a database of voltage sag is established; then the power quality information is acquired by power quality monit...
This paper demonstrates the mitigation of power quality issues in a grid connected wind energy conversion system using UPFC. The procedure to compensate the power quality issues like voltage sag and harmonics are presented. A Frame work for 25 bus test system is developed in the ETAP & load flow analysis &harmonic analysis is performed. It is observed that the UPFC is effective in compensating ...
Pattern Recognition Methodology for Network-Based Diagnostics of Power Quality Problems
Induction generators (IGs) are becoming important day by day in wind energy conversion. As such the numbers of IGs in a power system are increasing hence posing power quality problems. When large numbers of IGs are switched on or switched off from a circuit give rise to transients in the power system. In this paper authors tried to explore the effect of machine parameters on starting transients...
This paper aims to give a full study of the dynamic behavior of a mono-phase active power filter. First, the principle of the parallel active power filter will be introduced. Then, a dimensioning procedure for all its components will be explained in detail, such as the input filter, the current and voltage controllers. This active power filter is simulated using OrCAD program showing the validi...
Variability of photovoltaic (PV) power output is a potential concern to utilities because it can lead to voltage changes on the distribution system and have other adverse impacts on power quality unless additional equipment is added or operational practices are changed to mitigate these effects. This paper develops and evaluates a simple yet novel approach for quantifying irradiance variability...
The assurance of power quality depends on factors which influence the performances of the availability: the reliability and its support – the maintenance. This paper deals with the interactions between the indicators of reliability, maintenance, availability and with the methods for the calculation of the reliability indicators. For an overhead line of 110 kV the characteristics of the reliabil...
