| With the rapid development of the Chinese economy, electric power consumption also rises fleetly. In recent years, the rising speed of electric power consumption is higher than that of economy development remarkably. Electric power resource has become very scanty. Hence, how to economize energy sources and reduce wastage has become a hot problem researched in recent years.The main feature is combining the SCR Power Conversion and Intelligent Control System modules, the Power modules isolate high-voltage and low-voltage using Substation Converter Reactance, getting the first winding of Reactor (high-voltage) and street lamp in series, increasing the second winding (low-voltage) in the reactor. The secondary coil ,the SCR and the control systems of fuzzy control algorithms are associateing together, it alter the low-voltage to control its high voltage windings changes, thus reach the terminal of changing the street lamp's voltage signal, to carry out energy-saving and Soft Start.In this thesis, the intelligent system of energy-saving and controling street lamp which based on fuzzy control algorithm has been analysed and researched deeply. We discuss the concept of the intelligent system of energy-saving and controling street lamp, and introduce, the system design of the installation, operation. we detailed analysis the hardware circuit design with a control unit of 80c51, and its electrical connection. Against a street lamp voltage control it design software, using the fuzzy control thought. We simulate the system, and simulation results show the feasibility of the program. Thereby we establish a real system through system test, and get the results.Experiments show that the intelligent system of energy-saving and controling street lamp can significantly improved the street lamps' electricity efficiency and improve the rate factor in energy.Nowadays, while is conservation and rational utilization of power resources, the device has a very broad social and business prospects. |
