As the rotor offset is increased, both the UMP and the radial vibration at 0 Hz (the DC component, reflecting the mean value of the curves) and 100 Hz (the 2nd harmonic component) will be prominently magnified; see Figures 5(c) and 5(d).
Therefore, to calculate the instantaneous values of the current and voltage in the elements of the estimated model of the electric power grid, the harmonic component of the magnetizing currents [i.sub.0i](t) of the power transformer is preliminary determined [mathematical expression not reproducible] (6)
The proposed microstrip subharmonic mixer is used to downconvert a millimeter wave Ka band RF input signal ([f.sub.RF] = 39.75 GHz) to an intermediate frequency ([f.sub.IF] = 3.95 GHz), by mixing the input signal with the second harmonic component of a fundamental LO signal (fLO = 17.9 GHz).
where [U.sub.CB] is the voltage at the terminals of the CB at the industrial frequency (main harmonic voltage), in calculations it is allowed to use the nominal voltage of the CB [U.sub.nom,CB] as [U.sub.CB]; n is the number of the harmonic component; [U.sub.nCB] is the voltage of the n-th harmonic on capacitors.
where [x.sub.r,m](t) represents the m-th harmonic component of respiration with amplitude [a.sub.r,m] and angular frequency [[omega].sub.r,m] for m = 1, 2, ..., M, e.g., the original respiration component with m = 1, and [theta] denotes the total accumulated phase residual.
This term induces an important fifth harmonic component since the d[[lambda],.sub.PM,0]/d t harmonics different than the fifth and its multiples are null, as proved in Section IV.
fundamental harmonic component of the trapezoidal and the sinusoidal BEMFs is 95.88V.
In the frequency band which is lower than dozens of MHz, the electromagnetic wave in the transmission line mainly consists of the 0th harmonic component [31].
With this painting, Arias communicates that "it is necessary to realize the individuality that we represent culturally and socially, to respect and coexist with the other colors of this social rainbow, to be a single harmonic component".
Therefore, it is possible to eliminate k-1 harmonic component with SHE technique [1], [7].
For higher voltage consumers, they are required to meet the following conditions: the individual harmonic component (one per cent to three per cent), harmonic distortion (1.5 per cent to five per cent), anti-islanding (0.2 seconds for frequencies above 50.5Hz and below 47.5Hz), DC power injection (less than one per cent) and flicker (not creating objectional flicker).
In [9,10], it transforms the harmonic component to the DC component through multisynchronous rotating coordinate transformation; thus, traditional PI controller can be utilized to track the harmonics with zero steady-state error; however, it is too complicated.
