Vestas 850 kW 50 Hz LVRT Undervoltage Trip

I am performing dynamic simulation with several Vestas 850 kW WTG Units. I keep on receiving an error "LVRT Undervoltage trip at time 0.1917 s". This is just after initialization. The parameters of the vestas dynamic model is based on the model documentation. The load flow conditions are ok: terminal voltage at the WTG bus is within the nominal value.

What could be the reason for this error?

This sounds like a question to ask Vestas.

It's very difficult to answer a question such as yours without having access to your files to replicate the issue. Vestas are usually quite helpful if you're working on one of their projects.

Do you have a channel with the terminal voltage? Does the voltage decrease in the simulation or is it constant? What are the settings for the undervoltage relay?
