Abstract
A hydroelectric power generation system includes a water turbine disposed in a channel that carries a flow of a fluid, a generator driven by the water turbine, and a controller that performs a first control. The channel includes a first channel located on an inflow side of the water turbine. The controller controls, 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.
Claims13
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,
- the first channel including a water turbine channel through which at least part of the fluid that is to flow into the water turbine flows, and a branch channel that branches from the water turbine channel,
- an outlet of the branch channel being connected to a branch reservoir, the outlet of the branch channel not being connected to a downstream 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, and
- the controller being further configured to perform the first control so that an integrated flow rate of the fluid in the branch channel approaches a target integrated flow rate.
