Impact of Distance on the Harmonic Active Power and Energy Metering at the Load

摘要

A nonlinear load connected to the system draws non-sinusoidal currents, leading to generation of harmonics of nth order. The active power developed by the load, combines with the fundamental active power being consumed by the load and effectively reduces the overall value of active power. When this active power is measured by the energy meter over time, there would be loss to the power distribution company and unplanned power deficiency in the system. The effect of the factors like electrical distance from the source, the type and combination of linear and nonlinear loads is studied in this paper. MATLAB-based simulation is executed on a three-phase system using Thyristor and IGBT-based switches and the results shall be analyzed.
