要約(英語): Pumps are commonly used to supply and distribute water as the basic facilities in domestic water and sewage service businesses, which have aging facilities, have a shortage of experienced technical personnel, are experincing a dire financial situation, and so on. Since pump failure has a significant impact on plant operation, online monitoring technology is expected to improve the efficiency of diagnosis and inspection. This paper proposes a method for quantifying pump performance to monitor pump degradation by using online monitoring data accumulated with a supervisory control and data acquisition (SCADA) system. The proposed method estimates the performance of each pump from the measured values at the confluence of pipes with the least-squares method and respective on-off signals. From the viewpoint of practicality, the accuracy and usefulness of the proposed method were evaluated by the data acquired from the actual water supply system and the results generated by computational simulation.
