Excitation type
Example of the importance of lower and upper limits for setpoints
4 mA is set as the initial value for the active power limitation setpoint and 16 mA is set as the end
value for the active power limitation setpoint. If the grid operator sends a signal of 3.5 mA to the
Cluster Controller, the Cluster Controller then classifies this signal as 4 mA because the value of
4 mA is set as the lower limit for the active power limitation setpoint. If the grid operator sends a
signal of 17 mA to the Cluster Controller, the Cluster Controller then classifies this signal as 16 mA
because the value of 16 mA is set as the upper limit for the active power limitation setpoint.
