<P>PROBLEM TO BE SOLVED: To plan an optimum water level while reducing an ineffective discharge flow rate. <P>SOLUTION: An operation planning system 30 reads actual values of a pondage and an inflow out of a result database 335, calculates a past ineffective discharge amount of discharge which is not used for hydraulic power generation, and calculates an upper-limit pondage (V<SB POS="POST">max,</SB><SB POS="POST">t</SB>) for each season to subtract the upper-limit pondage according to the ineffective discharge mount. The operation planning system 30 calculates a maximum operation waver level (H<SB POS="POST">max,</SB><SB POS="POST">t</SB>) from the upper-limit pondage (V<SB POS="POST">max,</SB><SB POS="POST">t</SB>) and a model (B2), acquires a predicted value of an inflow for each season (t), and varies a water level (H<SB POS="POST">t</SB>) at the start of each season (t) and a waver level (H<SB POS="POST">t+1</SB>) at the end of the season (t) within a range equal to or less than the maximum operation waver level (H<SB POS="POST">max,</SB><SB POS="POST">t</SB>) and also varies an inflow (R<SB POS="POST">t</SB>) within a predetermined range to calculate power generation electric energy by applying the varied water level (H<SB POS="POST">t</SB>, H<SB POS="POST">t+1</SB>) and varied inflow (R<SB POS="POST">t</SB>) to models (B1-B9), thereby determining a combination of water levels such that the total of power generation energy becomes maximum. <P>COPYRIGHT: (C)2012,JPO&INPIT |
