Background
In the Norwegian power market, reversible
pump turbines (RPT) for the most part change
from pump to turbine mode of operation on a
seasonal basis. In the future power market, the
RPT are often given the role of balancing the
power production.
This will require more frequent and faster
changes between the operational modes. The
machines experience higher loads in off-design
and start and stop operations.
Through laboratory experiments, the objective
of this work is to investigate the rapid change
from pump to turbine mode of operation. And
especially look at the characteristics, loads and
stability concerns in this fast change from pump
to turbine.
