Generator Trip Generator Trip
a generator trip is when a generator suddenly and unexpectedly loses it's external load a generator trip is when a generator suddenly and unexpectedly loses it's external load
oftentimes this is when a power plant is disconnected from the grid for one reason or another oftentimes this is when a power plant is disconnected from the grid for one reason or another
in this case we just: in this case we:
- check if internal power storage of turbine is increasing - check if internal power storage of turbine is increasing
- check that there is at least 5% energy fill, preventing false trips with periodic power extraction
that means there is no external load and there will be a turbine trip soon if this is not resolved that means there is no external load and there will be a turbine trip soon if this is not resolved
