Differ ent turbine types have quite different efficiency profiles when the turbine discharge deviates from the optimal value (see Figure ). adapted to the duration curve of the inflow. This does not mean that the flow rate is m 3 /s for 60% of the time, but that the flow is equalled or exceeded for 60% of the time, so basically the flow is at this flow or at a higher flow for 60% of the time. This is now a Flow Duration Curve. If you look at the flow value at '60% exceedence' you will see that it is m 3 /s. The view defaults to the last 90 days . The Power Duration Curve is your best effort power (in Watts) at any given duration (up to five hours) that you’ve done over the defined period of time.
