【 摘 要 】

Okutataragi Power Station is located in Tataragi, Asago City Hyogo Prefecture, Japan. The maximum total output is 1932 MW. It is the largest capacity commissioned hydropower station in Japan. In order to reduce the fossil fuel cost and improve the efficiency of generation in partial load, KEPCO decided to enlarge the LFC (Load Frequency Control : This control changes the generation output at intervals of several minutes to 10 minutes in order to compensate the load change and maintain the grid frequency.) capacity by the renovation of existing pumped-storage power station from fixed speed to adjustable speed. Now, the commissioning test of the first unit was finished and the installation of the second unit is proceeding.
