Definition: Energy over one Power Cycle trajectory divided by the Cycle trajectory time. [kW]
Notes:
Figure 1: The figure shows the instantaneous electrical power measured at the generator/motor of the AWES for a ground wind speed of 6 m/s (normally a wind speed given at pattern trajectory height would be better).
The blue areas indicate the reel out phase of the cycles (positive power) while the red areas indicate the reel-in phase of the pumping cycles. The average cycle power is indicated in the figure by the horizontal dashed line.
Figure 2: The figure shows the instantaneous mechanical power for an arbitrary 150 kW system during one pumping cycle.
