Design Of Control System For Double Pick Type Hydro Turbine Based On Plc

Hydropower station's monitoring system is the foundation of hydropower station's integrated automation and it is the precondition to realize the unattended mode too. Along with the speed development of computer technology and electronic technology, the hydropower station's monitoring system with advanced technical functions and the advantage of stable and reliable running is used widely. For small hydropower station is to improve the operation of the automation degree and to reduce the investment, the small hydropower station is an important principle. While the computer monitor PLC is hydropower station is an important part of, is suitable for industrial site control equipment, computer monitoring system is the core of hydropower station, the direct components determines the whole performance of the working performance of the monitoring system..This topic is a small hydropower station for research object, detailed introduces the design of the monitoring system of power and composition. Small hydropower station, the paper analyses the development process monitoring technology. According to the specific parameters of the power unit of the selection and speed control system based on the structure and investment saving and new technology, new equipment, "the spirit of the double pick type selection, equipment selection digital programmable torque motor speed. Expounds the design requirements of hydropower monitoring system, analyzes the small hydropower station is applicable to the monitoring system of the structure and the structure of the monitoring stations, the integral design of the system, the control structure, functional unit centralize control of the module, etc. The fourth chapter of this software design, system of PLC using mature technology of PLC controller FX2N mitsubishi series, as to the turbine units start and stop, adjusting etc. Function. The fifth chapter is touch screen production process, the design process of hydro-generating human-machine interface. Finally objectively evaluate all aspects of the system performance and the insufficiency, and the future development was prospected.System screen as centralize control unit of man-machine interface, and according to the function of various picture done configuration, including the problem. an control interface, temperature monitoring interface, remote sensing etc. The control system has been successfully operation, the actual operation results show the system can meet the requirement of practical application, and reach the expected goal. The system performance is superior to power, and brings great economic benefits and realize the real meaning of "the unattended mode".
