Turbine Trip
a turbine trip is when the turbine stops, which means we are no longer receiving water and lose the ability to cool.
this can be identified by these conditions:
- the current flow rate is 0 mB/t and it should not be
- can initially catch this by detecting a 0 flow rate with a non-zero input rate, but eventually the steam will fill up
- can later identified by presence of steam in tank with a 0 flow rate

Generator Trip
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
in this case we just:
- check if internal power storage of turbine is increasing
that means there is no external load and there will be a turbine trip soon if this is not resolved
