Claim 12:
13. A hydroelectric power generation system comprising:
a water turbine disposed in a channel configured to carry a flow of a fluid therethrough;
a generator configured to be driven by the water turbine; and
a controller configured to perform a first control,
the channel including a first channel located on an inflow side of the water turbine, and
the controller being configured to control, in the first control, a flow rate or a head of the water turbine so that any one of
a pressure of the fluid in the first channel,
a flow rate of the fluid in the first channel, and
a liquid level of the fluid in a first reservoir from which the fluid flows out to the first channel

approaches a first target value,
the first channel including
a water turbine channel configured to carry flow of at least part of the fluid that is to flow into the water turbine therethrough, and
a branch channel that branches from the water turbine channel,

the branch channel being provided with an adjustment mechanism configured to adjust a flow rate or a pressure of the fluid, and
the controller being further configured to control, in the first control, the flow rate or the head of the water turbine so that a pressure of the fluid near an inlet of the adjustment mechanism approaches the first target value.
