Abstract

PURPOSE:To intend to reduce the construction cost of an electric power plant by utilizing an abolished underground cavity as a downward reservoir out of two reservoirs,upward one and downward one. CONSTITUTION:In an abolished underground cavity 1, a downward pond(1a) and a machinery room(1b) are formed, moreover a ground upper pond 3 and a shaft 4 are formed. When electric demand is little at night, a pump 7 is driven by surplus electric power from a transmission line 9 through a electric motor(7a) for pumping up the water of the downward pond(1a) to the upper pond 3 through a flow up pipe5. Next, when electric demand is excessive in daytime, an electric power switching device 10 is operated for connecting the transmission line 9 to a generator 8 side, and the water of the upper pond 3 is fallen to the downward pond(1a) through a flow down pipe 6 by which the generator 8 is rotated through a hydraulic turbine (8a) to generate electric power and supplies supplimental electric power to the transmission line 9. In such manner, because of utilizing abolished underground cavity to form downward reservoir, the construction cost becomes cheap and further-more an effect is also gained, to reduce water decrease due to evaporation.

。(2) Conventional technology Conventionally, this type of pumped storage power generation system involves constructing artificial reservoirs at upper and lower locations in mountain areas, and connecting upstream pipes and downstream reservoirs between the upper and lower reservoirs. A pump is connected to the upstream pipe and a water turbine of a generator is interposed in the downstream pipe near the reservoir at the lower position, so that surplus power can be used when power consumption is low at night. The water from the lower reservoir is pumped up to the upper reservoir via an upstream pipe, and when power consumption is excessive during the day, the water from the upper reservoir is pumped to the lower reservoir via a downstream pipe. The water flows down through the canal and rotates a water wheel to generate electricity.
