Figure 10-11. Q(P) Characteristic Curve Example
The network operator defines the characteristic curve during network planning. Remote setpoint
adjustment is not provided. However, it is possible to switch from this mode to another reactive power
control mode at any time through logic. Logic can also be set to switch reactive power control modes
upon a remote communications failure. Figure 10-12 illustrates the LVRT Mode Select logic element. See
the BESTlogicPlus section for details.
