ENERGY SELF-SUFFICIENT STREET LIGHTS (ESUS)
KOMUNALNA ENERGETIKA / POWER ENGINERING, 25
Within diploma work "The impact of street lights on energy transmission losses and possibility for realization of energy self-sufficient street lighting" were constructed two examples of energy self-sufficient street lights (ESUS). The lamp is not connected to the electricity grid and for its normal operation use energy from the wind and sun. At the top of the street pole is mounted vertical axis wind generator, which begins to operate at very low wind speeds (2-3 m/s). On the circumference of the pole is installed thin film solar panel that generate solar energy throughout the day. Possibility of installed passive infrared motion sensors and GSM monitoring and management system results as reducing electricity consumption of street lamp up to 80 percent.
