When the controller is started, the default output value of active and reactive power from the PCU is zero.
When the target value for active power is started with 1.0, the output goes from 0.0 to 1.0 in several steps, because the wind turbines stop after the short zero set point and need more time to restart. This is not good.
Is there any way to set the start value of the PCU for active power to 1.0?
Maybe the GO/TP active power start value is 0.0 and not 1.0 and that is the problem, but I tested setting udtGlobalData.GridOperator.Pcu[1].ControlObjects.Setpoints.rRawActivePower to 1.0 before activating the PCU parameters, which does not work.
Use Library Version 3.0.0 (2021.6.0) and the sample project with two PCUs as project base.
I am guessing that this question relates to the Power Control Unit app in the PLCnext Store?
If so, then I’d like to suggest that you contact the developers of that app, using the Contact button on the app page in the PLCnext Store. The developers should be able to help with questions about the app.
