The Theory and Practice of Optimal Operation and Scheme Evaluation Technology for Water Supply System Based on Heuristic Algorithm

In this article, the evaluation technology is proposed for optimal operation scheme based on safety water supply, in order to verify the security and economy of the optimal operation scheme and provide the evidence for optimal operation decision-making. Four evaluation indices, named flow coincidence, pressure coincidence, pump efficiency and direct power consumption respectively, are established. Meanwhile, the online optimal operation model of water supply system is established and solved by heuristic algorithm. On this basis, the corresponding computer program is developed using Visual C++ 6.0 for the implementation of the optimal operation and scheme evaluation technology. In addition, the established model and four evaluation indices are applied in one southern city of China practically, and achieve good effect. At the same time, the practical application value of the technology is verified on the aspects of ensuring safety water supply and reducing energy consumption.
