FIG. 4.25 Performed waveform analyses by designed PLC modems for measured, modulated,
demodulated and calibrated data.

waveforms stand for the measured voltage, current and power values of WECS
and solar plants, respectively. Modulated wind measurement, demodulated
wind measurement and calibrated wind measurement are shown in third,
fourth and fifth waveform of Fig. 4.25, respectively. In addition, these trans-
actions are also realized for the solar plant system in a similar way. Modulated
measurement of solar plant, demodulated measurement of solar plant and cal-
ibrated measurement of solar plant are illustrated in sixth, seventh and eighth
waveform of Fig. 4.25, respectively. By employing various carriers with dif-
ferent frequencies, modulated data of solar plant are combined with modulated
WECS data.
The presented analyses for the second case study clearly show that designed
monitoring system can be efficiently used to track different parameters of sev-
eral energy sources. Furthermore, the presented multi-channel PLC system can
be simply arranged to monitor much more parameters of energy generation and
distribution systems. Moreover, this system can be also exploited as a control
system by sending any control data from grid side to energy source side.
