Water supply system is a complex system. Aimed at the puzzle of being very heavy in energy consumption of system control and being not better in water supply quality resulted from being inappropriate in control strategy, The paper researched on the energy conservation strategy and control mechanism of water supply system. It discussed the cybernetics characteristic of water supply process, proposed the intelligence based fusion control strategy and the energy conservation executing strategy, and analyzed the control model of water supply purifying process and the control algorithm of constant pressure control system. Based on the comparative study of simulation experiment, the display of response curve demonstrated that the intelligence based control strategy would be better than conventional PID control method. The simulation results show that the proposed strategy combined intelligence based fusion control with speed control by frequency variation has better application prospect in water supply system.

Supply Systems

Water supply systems are dynamic in nature, owing to the effect of climate change and consumer demand uncertainties. The operation of such a system must be managed effectively to meet up with the uncertainties, thus posing a key challenge. Unfortunately, previous information and communication technology (ICT) solutions could not provide the necessary support for applications to deal with the dynamics of the changing physical environment. Nevertheless, tremendous growth in technology offers better possibilities to enhance water supply systems’ operations. As a result, development in technology in sensing and instrumentation, communication and networking, computing and control is now jointly integrated with water supply system infrastructures to enhance the water system operations. One such technological paradigm shift is the cyber-physical system (CPS). In this paper, we present the concept of the CPS in the water system context and investigate the CPS applications to water supply system monitoring. Also, the various applications of CPSs and the application domain requirements are outlined. More importantly, research studies on its application to water system monitoring are scrutinized. As such, key challenges sounding the applications in WSSs are identified. We then outline the areas of improvement for further studies.
