STAND-ALONE STREETLIGHT FOR DISPLAY OF GENERATION INFORMATION OF WIND TURBINE AND SOLAR POWER SYSTEM

摘要

PURPOSE: A stand-alone streetlight is provided to calculate a power generation quantity and a carbon dioxide reduction quantity by adopting a wind power generator and a solar power system in the stand-alone streetlight and to simultaneously store generated power while displaying a temperature. CONSTITUTION: A stand-alone streetlight for displaying power generation quantity information includes a streetlight structure, a lamp, the wind power generator, the solar power system, a secondary battery(600), a first current sensing device(110), a second current sensing device(120), a temperature measuring device(130), a solar radiation quantity measuring device(140), an individual power generation quantity calculating unit(160), an accumulated power generation quantity calculating unit(170), a carbon dioxide reduction quantity calculating unit(180), and a main control unit(100). The secondary battery stores the electricity generated in the wind power generator and the solar power system. The first current sensing device measures a current value from a power generation quantity of the solar power system. The second current sensing device measures the current value from a power generation quantity of the wind power generator. The temperature measuring device measures a temperature of a solar cell and a surrounding temperature. The solar radiation quantity measuring device measures a solar radiation quantity. The individual power generation quantity calculating unit calculates each power generation quantity using the current value of the first and second current sensing devices. The accumulated power generation quantity calculating unit calculates an accumulated power generation quantity. The carbon dioxide reduction quantity calculating unit calculates a carbon dioxide reduction quantity. The main control unit performs control by obtaining a power generation quantity value, an accumulated power generation quantity value, a measured temperature value, and a solar radiation quantity value.
