[Abstract]:With the increasingly serious problems of water resources and traditional energy, it is imperative to develop new energy for high energy consumption industry. Seawater desalination technology is the key to solve the problem of water resources at present, and wind energy is also one of the core of new energy industry. To develop wind energy in seawater desalination can be used as an important means to deal with the crisis of water resources and traditional energy. Based on the National Science and Technology support Program of Ministry of Science and Technology, the project of 200 tons / day wind desalination in Tongzhou Bay, Nantong, Jiangsu Province, this paper analyzes and studies the seawater desalination system directly used by wind power, including the following contents: 1. It is shown that the wind net complementary energy supply module can adjust the output power according to the external wind speed in real time, and the integrated unit of pressurization and energy recovery can produce fresh water through reverse osmosis membrane. On this basis, the wind net complementary energy supply module is put forward in this paper. The wind water desalination system is composed of an integrated unit of pressurization and energy recovery, and the principle and structure of the system are studied. In view of the unstable phenomenon of the pressure and energy recovery integrated device caused by the excessive wind speed, this paper analyzes the characteristics of the hydraulic system of the pressure and energy recovery integrated device, and establishes the mathematical model. Based on fuzzy PID control theory, the solution of instability is proposed, and its simulation model is built by AMESim environment. The simulation results of hydraulic system under different control strategies are compared, and the feasibility and effectiveness of the proposed scheme are verified. 3. Based on the WinCC configuration software, this paper designs the SCADA wind power direct seawater desalination system, and analyzes in detail the structure of local microcomputer monitoring and GPRS wireless remote monitoring in the central control room, which provides an effective guarantee for the field equipment data monitoring.
