Low Voltage Ride Through

[petrovich]

Can anyone help me with the concept of Low Voltage Ride Through?

My understanding is that in solar farms we do not want to trip the system when a transient fault happens on the line but I am not sure how this is accomplished(probably via protection settings) and how it affects inverters?

It is a very interesting issue, indeed. But if you intend to go deeply see:
