Electric Power Quality Measurement
The proliferation of non-linear and time-variant loads is causing a number of disturbances on the electric network, from a more and more significant distortion of both currents and voltages, to transient disturbances on the supply voltage. In this respect the electric network behaves as an "healthy carrier" of disturbances, so that a disturbance generated by one customer can be distributed to o...

متن کاملChallenges and Trends in Analyses of Electric Power Quality Measurement Data
Power quality monitoring has expanded from a means to investigate customer complaints to an integral part of power system performance assessments. Besides special purpose power quality monitors, power quality data are collected from many other monitoring devices on the system (intelligent relays, revenuemeters, digital fault recorders, etc.). The result is a tremendous volume of measurement dat...
متن کاملA New Algorithm for Reactive Electric Power Measurement
In this paper a Walsh function (WF) based new algorithm for reactive power measurement is presented. The proposed algorithm allows the convenient calculating process to obtain a reactive power from the entire instant power signal without time delay between current and voltage signal. To test the validity of the suggested approach the simulation tool has been developed by use of “Matlab 6.5” sof...
متن کاملPower Quality Impact of Electric and Plug-in Hybrid Vehicles
The continued increase of gas prices and concerns on greenhouse gas emissions in recent years have led to the steadily increasing acceptance of electric vehicles (EVs), especially the plug-in hybrid electric vehicles (PHEVs), by consumers. It seems that PHEVs are poised to become a serious contender for a noticeable share of the car market in the near future. As PHEV draws power through power e...
