Obtaining Feasibility of Power Flows in the Deregulated Electricity Market Environment
Published by Mariusz DRABECKI, Eugeniusz TOCZYŁOWSKI,Warsaw University of Technology, Institute of Control and Computation Engineering Abstract. In this paper we analyse a power dispatch method for obtaining feasible power flows, both active and reactive power, in terms of satisfying the transmission, voltage level and voltage angles’ constraints, under assumption that supply of electric power isContinue reading “Obtaining Feasibility of Power Flows in the Deregulated Electricity Market Environment”
Steps to Find the Source of Harmonics
Published by David Horning, November 2014. Power Monitors, Inc., White Paper: Steps to Find the Source of Harmonics Abstract. Harmonics are “Non-Linear” current or voltage in an electrical system. Any waveform that deviates from a perfect sine wave has harmonics. Any nonlinear load draws harmonic currents and therefore produces harmonic voltage distortion, by producing non-sinusoidalContinue reading “Steps to Find the Source of Harmonics”

Combining Waveforms in a Power System to Cancel Harmonic Components
Published by Alex Roderick, EE Power – Technical Articles: Combining Waveforms in a Power System to Cancel Harmonic Components, August 23, 2021. Harmonics can cause transformers to fail, motors to burn out, circuit breakers to trip (nuisance tripping), and neutral conductors and other parts of a power distribution system to overheat. Severe overheating leads to electricalContinue reading “Combining Waveforms in a Power System to Cancel Harmonic Components”
Electric Power Quality Measurement
Published by Alessandro Ferrero, Dipartimento di Elettrotecnica – Politecnico di Milano – Piazza Leonardo da Vinci 32 – 20133 Milano – Italy Abstract – 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 transientContinue reading “Electric Power Quality Measurement”
