熱水蓄熱発電の特性と応用に関する研究 : 600 MW級火力発電設備と組合せた蓄熱発電プラントの貯蔵発電効率の評価

Due to the change of life style and operation of industries, the gap of electric power demands between day time and night time is increasing year by year, and some of the thermal power plants are compelled to shut down or partial load operation, with lower thermal efficiency. The pumped storage power plant is the only commercialized system to mitigate such power demand gap. However, the locations suitable for a pumped storage power plant are limited. It would not be, therefore, easy to construct new pumped storage power plants in substaintial scale. The hot water storage power plant, added on the existing thermal power station, is proposed as one of the most effective technology to solve such severe situations. This paper is a brief discussion on the feasibility of the hot water storage power plant application to the utility power generation industry.
