Background
Norwegian hydropower plants are operated
with an increasing number of start-stop
operations, and variation of produced power.
In addition, large hydropower pumped
storage projects may be constructed in the
near future.
To enable more flexible operation of the
power plant, surge tanks may be constructed.
The surge tank enables more rapid changes of
the produced power, and reduces the pressure
forces occuring during such maneuvers. The
surge tank is also beneficial for regulation stability in large hydropower plants.
This PhD project seeks to investigate the optimum design of surge tanks, mainly focusing on
the air cushion surge tank.
