Street Lamp

This research proposes a simple but very effective method to determine faulty street lamps by utilizing a microcontroller associated with relay control technique to analyze the current consumption of the lamps. With such approach, the lighting system can automatically report the number and the position of the faulty street lamp to the operator in the control room. As a consequence, the faulty street lamp can be quickly repaired. The user interface and controller are programmed in LabVIEW software. The result is verified by modeling street light system using five 100 watts incandescent light bulbs connected in parallel. The results of this research can be applied to improve the existing street light system especially in Thailand. Furthermore, equipment used in this research is cost effective.

The static and dynamic reserve of voltage in input of voltage autonomous inverter being a component of parallel power active compensator on the physical realizability of inactive current components with the determined response, pulsations amplitude and commutation frequency of invertor switches was considered. Invariance of closed system of automated power quality regulation with relay control to the parametric and external disturbances is provided by the dynamic voltage reserve calculated from the obtained expressions. Special attention is given to the possibility of using this system in mining. Proposed approaches also can be used in the training of engineers in the electrical and mining industries.
