Abstract
An electric power measuring system wherein the watt-hour measurements are adjusted to account for the economic effects of harmonic currents and voltages. Well known techniques are used to acquire frequency spectra that represent the voltages and currents present at the measuring point. These spectra are used to calculate power flow direction and magnitude at various frequencies. Weighting functions are applied to power flows at frequencies other than the fundamental frequency. The weighted power flow is used to calculate an harmonic-adjusted watt measurement, which is then accumulated to form a harmonic-adjusted watt-hour measurement. The weighting functions can be selected to provide an economic incentive for a power consumer to consume power in a way that matches the goals of the power provider.
