유한수원을 고려한 Advanced-Pressure Driven Analysis 모형의 개발 및 적용 = Development and Application of Advanced-Pressure Driven Analysis Model Considering Limited Reservoir

국문 초록 (Abstract)

상수도 관망해석 모형은 크게 두 가지로 구분되며, 주로 정상상황의 시스템 해석에 적용되는 Demand Driven Analysis (DDA)와, 수압이 저하되는 비정상상황 해석에 적용되는 Pressure Driven Analysis (PDA)가 있다. 하지만 DDA와 PDA의 경우, 수원이 무한한 용량을 갖는다는 가정을 포함하므로, 수원의 저류량 변화에 따른 영향을 고려하지 못하는 단점이 있다. 따라서 본 연구에서는 유한수원 개념을 도입한 Advanced-Pressure Driven Analysis (A-PDA) 기법을 제안하였으며, 가상의 상수도 관망의 해석에 적용하여 그 적합성을 검증하였다. 적용 결과 본 연구에서 제안된 A-PDA는, 수원의 시간에 따른 저류량 변화를 효과적으로 반영하여 보다 신뢰도 높은 시간 및 공간적 공급량을 산정할 수 있는 것으로 나타났다.

다국어 초록 (Multilingual Abstract)

Hydraulic analysis model of water distribution systems can be divided into two types, one is Demand Driven Analysis (DDA) which applies to a normal condition, and the other is Pressure Driven Analysis (PDA) for abnormal condition modeling with pressure deficiency. However, both of hydraulic analysis models, the storage capacity of water source is assumed as infinite, and therefore, the effect by water storage variation of source is not considered. In this study an Advanced-Pressure Driven Analysis (A-PDA) with limited reservoir concept is proposed, and it applies to hydraulic analysis of hypothetical water distribution system for verification of proposed method. The results show that, the A-PDA can effectively consider the water source storage variation over time, and it can calculate more reliable temporal and spatial water supply.
