Abstract
A power generation system (10) according to the present disclosure includes: the first underground structure (121) provided in an underground (A) and defining an internal space (IS) ; a water discharge controller (123) that controls discharge of water (wt) retained in the internal space (IS) ; and a power generation unit (124) disposed at a position where the water (wt) is retained in the internal space (IS) or a pipeline (127) communicating with the internal space (IS), the power generation unit (124) generates electric energy from hydraulic energy generated by discharge of the water (wt).
Claims10
A power generation system comprising:
- a first underground structure provided in an underground and defining an internal space;
- a water discharge controller configured to control discharge of water retained in the internal space;
- and
- a power generation device disposed at a position where the water is retained in the internal space or a pipeline communicating with the internal space, the power generation device configured to generate electric energy from hydraulic energy generated by discharge of the water.
A power generation method comprising:
- a water level detection device that detects water level and determines the water level is equal to or higher than a water level threshold;
- a drainage control device drains the water if the water level is higher than the water level threshold;
- a power generation device generates electrical energy from hydroelectric energy accumulated in association with the drained water;
- and
- an operation instruction device determines amount of electrical energy being generated by the power generation device is decreasing or increasing and stops water drainage if the amount of electrical energy being generated is decreasing.
