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
