摘要

本文旨在設計及應用含電能管理之太陽能及風力的獨立型照明系統。系統採用太陽能及風力作為發電的來源，可提高照明系統運轉的可靠性。在發電系統設計方面，採用升壓型直流轉換器作為充電電路，並搭配最大功率追蹤之控制法則，使太陽能電池與風力發電機輸出最大功率。在照明系統的電能管理方面，根據人類夜間的作息習慣，提出區段調光曲線，作為夜間照明管理設計的準則；並藉由判斷季節以決定變流器之功率開關於各區段的導通責任週期，作為照明負載輸出功率的依據，進而達到節能及持續照明之目的。在系統整合方面，採用數位信號處理器作為發電系統及照明系統的控制核心，以簡化控制電路。由區段調光的實驗結果顯示，當蓄電池組電壓為48.8 V時，照明系統於夏秋及春冬季節之節能百分比約13.3%及16.4%，能達到節能及持續照明的要求，並符合綠色照明之實用潮流。

The design and application of a stand-alone lighting system with solar-wind hybrid energy is proposed in this paper. The solar and wind energy are adopted to increase the reliability of the lighting system. In the generation system design aspect, the DC-DC boost-type converter is used as the charging circuit with maximum power point tracking (MPPT) strategy for the solar-wind hybrid generation system. In the lighting system, we propose a time-zone dimming curve, based on people's evening activity habits, to provide guidelines for a night lighting management; we also use season's difference to determine the inverter's power switching for each time-zone's conducting duty ratio, as a guideline for each lamp's output power in each dimming time-zone, to reach the purpose of energy conservation and continuous lighting. The experiments are performed by controlling the generation and lighting system, and the whole system is executed by a digital signal processor. The experimental results from said time-zoned dimming indicate that when the battery bank voltage is 48.8 V in summer-fall and spring-winter season, the energy-conservation percentage ratio is approximately 13.3% and 16.4%, respectively. The solar-powered dimming system proposed and designed herein can meet the requirements of energy conservation and continuous lighting for the current trend of green lighting.
