The Design And Research On Automatic Control System For Three Gorges Permanent Water Plant

Water supply is concerned with the national economy and the people's living. With the improvement of people's live condition, the enhancement of labor productivity and the realization of building a well-off society in all-round way, the requirement for qualified water is more and more strict. As an effective method to ensure safety, continuous and high quality water supply, computer automatic control system is widely prospected in water plant.Based on the actual control system of the under-constructing Three Gorge permanent water plant and the technique of water purification, and combine with the water characteristic of the Yangtse River, the function and geographic location of the plant, this paper describes the design of the automatic control system of this work. In detail and, in the light of many prospects such as the usage, the peculiarity and the operation environment of this plant, this paper also illustrates the chemical dosing system, analyses the on-site test. The performance of the system ensure the safety and optimization operation of the water plant.Furthermore, the application of low voltage transducer in water work in the aspect of energy-saving and dose-consumption is also discussed in this paper...
