摘要

台灣大樓建築的自來水供應多採用重力水塔的間接供水方式；本研究使用EPANET水力分析模式，探討配水管網中屋頂水塔與地下蓄水池的取水時間，並建立由三棟大樓組成的多個建築物的配水管網系統。本研究同時藉由用戶需求模式、基本需求量和閥門控制等設定模擬參數，建立用戶需求和供水節點之關係；本研究也使用DMA（小區計量）的概念，分析多個建築物同時進水所引起的同步現象，並從儲水設備的體積比與使用端用水模式的方向導入，分析引起同步的因素及其對管網壓力波動的影響，並定義一個評估管網中多個建築物同步取水行為的強度指標(IS)。本研究最後提出了一種閥門或水泵操作時間的演算法(OSWSSA)，可以有效避免進水同步的發生和穩定管線的供水壓力。

Water supply systems (WSS) of tall buildings in Taiwan generally adopt the gravity-tower way to supply water. In the present study, a WSS layout was created for three buildings in a multiple-unit complex by using EPANET to trace the water intake time of roof towers and underground tanks in the network. A relation was made between user demands and water supply nodes via the design parameters of user’s demand patterns, base demands, and pump controls, etc. The synchronization phenomenon caused by multiple-buildings water intakes was analyzed using the concept of DMA (District Metering Area). Besides, the factors resulting in the synchronization and its impact on the pressure fluctuation were studied based on the volume ratio of water storage equipment and the demand pattern of users. An Index of Synchronization (IS) was defined to describe the influence level of the multiple-buildings intakes. Finally, an algorithm (OSWSSA) for operating-valve (or pump) schedules was proposed to avoid the synchronization and stabilize the pipeline pressure for water supply systems.
