摘要

本文係針對混合型再生能源應用於LED 路燈整合管理系統做為研究主軸，改
善以往系統之不足。過去再生能源系統存在三大問題：規劃時多為單一能源設計，
氣候條件差時無法維持穩定供電；電池放電若不經任何管理，長時間過放將嚴重
影響電池效能及壽命；LED 路燈佈光範圍不足，面對橫幅較寬道路光源無法擴及
內車道。
因此，本研究分別從發電端、蓄電端及應用端進行分析並開發解決方案。結
合兩種再生能源混合發電，利用氣候互補特性，讓系統具完整的供電調度，建立
發電監控及微型氣象站，瞭解混合型系統實際的發電效益；利用LED 晶粒可序列
控制之特性，開發PWM 電池管理系統，依據當天發電量多寡，調度市電及電池的
輸出比例，減少電池循環次數實現智慧型放電，藉以延長電池使用壽命；改善舊
有LED 路燈照明情況，基於LED 路燈為面光源特性，提出雙負載LED 路燈配置，
以光學模擬(DiaLux)將改善效果視覺化，達成兼顧照明與節能之雙贏，建置完成後
驗證其照明效果。
經六個月統計結果分析，發電量與氣候條件呈正比關係，太陽能發電仍比風
能穩定許多，額定430W 再生能源系統平均日發電量為0.386kWh；PWM 電池管
理系統約可延長2 倍電池使用壽命，並具LED 調光功能；雙配置LED 路燈完成安
裝後，內外車道照明不均的問題有顯著改善，平均照度及照明均勻度分別提升65%
及10%，改善後照明滿意度達96%，整套系統配合尖離峰時間控制，總節能率可
達74.4%。

This research was focused on the LED street light, which use hybrid renewable
energy integration management system. To modify the weakness of the system. There
are three problems in traditional renewable energy system: traditional system is
designed for single energy source. Therefore, its power supply is unstable when the
weather condition is not allowed. After the battery has been discharging without any
management for a period of time, not only its performance will be reduced, but also its
capacity and life will be damaged seriously. LED street lights have higher beam
intensity, which is more difficult to extended lighting area to inside lanes.
Therefore, research analyzes and develops solutions from the power generation
aspect, the battery aspect and application aspect. Combine two kinds of renewable
energy sources to supply the electricity and use their characters of weather
complementary to make the system owns the ability to switch power supplies.
Building generator monitor and a micro-meteorological station to find out the generate
efficiency of the hybrid system. Use the serializability of the LED grain to development
PWM battery management system. Schedule the output ratio of grid power and battery
base on the generated power in the day. Reduce the battery cycling times to achieve
intelligent discharge in order to extend the battery life. In order to improve traditional
LED street lights lighting conditions, by using an area of LED light source and set a
dual-load LED Street lights to improve the effect of visualization with optical
simulation (DiaLux,). To achieve the goal of lighting and energy saving solution, and
verify its lighting condition and energy using condition after the equipment are set.
After six months statistics analysis, generating power is proportional to the weather
iii
conditions. Solar power is more stable than the wind power. The total rated 430W
renewable energy systems generated average 0.386kWh power per day; PWM battery
management system able to extended approximately 2 times of the battery life, and
capable for light intensity adjustment. After dual-load LED street lights setup completed,
lighting uneven between each lane had significant improvement. The average
illuminance and uniformity-of- illumination increase of 65% and 10%. Survey shows
that satisfaction up to 96% after lighting improvement. Entire system with peak and
nonpeak time control, total energy saving efficiency can be up to 74.4%.
