Development of computational algorithms for pump operations and their applications to the system dynamics modelling of a water supply system. Issue 2 (3rd April 2017) - Park, Suwan
ABSTRACT: In this study, computational algorithms for the simulations of the operations of pumps for water distribution storage tanks were developed. The developed algorithms include pump operating rules for different electricity price schemes and operating situations such as normal and emergency conditions. The algorithms were programmed into System Dynamics modelling modules that can be used as basic building blocks when an SD model is constructed for the simulations of complex real-world water supply systems. Based on the basic SD modelling modules, a dynamic computer simulation model was developed for the simulations of the water supply system in Young-Jong island in South Korea where multiple local water sources are to be utilised. The developed model dynamically simulated the water levels in the water distribution storage tanks and estimated the pumping costs of the system according to the normal and emergency operational scenarios. During the emergency situation it was assumed that the local water sources will not be able to supply the assigned portion of demand. STELLA system dynamics modelling software was used for the modelling.
