In this mode the reactive power output of the machine is adjusted as the real power output fluctuates
(Q = f(P)).
A filter time constant setting is available for the measured power level. The characteristic curve is
specified by up to 10 points relating desired Q output to exported power. Perform linear interpolation
between the points. The active power coordinate for each point may range from 10% to 100% active
power and the range for the reactive power level must conform to Figure 10-10, below. Above 20% active
power, the reactive power range should be -0.33 to 0.33 per unit reactive power.
