DISTRIBUTION RESERVOIR WATER LEVEL SETTING DEVICE, DISTRIBUTION RESERVOIR WATER LEVEL SETTING METHOD, AND DISTRIBUTION RESERVOIR WATER LEVEL SETTING SYSTEM

摘要

This distribution reservoir water level setting device is provided with a recording unit, a simulation unit, a peak power assessment unit, and a power charge calculation unit. The recording unit records plant data and water demand data. The simulation unit calculates the amount of water sent to a distribution reservoir by a plurality of pumps on the basis of the plant data, calculates the water level of the distribution reservoir on the basis of the relationship between the amount of water sent and the water demand data, and increases or decreases the number of pumps when the water level approaches an upper or lower limit value for the distribution reservoir. The peak power assessment unit calculates a quantity of power and peak power on the basis of the amount of water sent. The power charge calculation unit calculates a power charge on the basis of the peak power and the quantity of power. The simulation unit establishes, as setting values, the upper and lower limit values for the distribution reservoir which minimize the power charge.
