摘要

本論文主要對本CCT實驗室與宇春綠能源科技股份有限公司合作開發之道路廢能儲存與發電系統之油壓發電研究。本系統以回收車輛在減速路段所損耗之能量，將其收集並儲存後轉換為可使用之電能，系統主要由受壓塊、位能槽及發電裝置等組成，其中，受壓塊係以數個小型活塞缸，利用車輛行經減速路段時壓縮流體至位能槽後，再釋放能量以驅動發電裝置。本論文針對使用不同之氣、液流體搭配不同之氣、液壓引動器進行技術探討，本研究中所建構之小型氣壓發電系統在使用90596.5cm^3之儲氣槽壓力範圍為1∼8kg/cm^2、搭配直徑為12.5cm之氣壓
缸驅動發電機，而且發電機負載為20歐姆之水泥電阻時，得到在氣體壓力為1.5kg/cm^2時，發電效率達8.26%為最高。另外，小型油壓發電系統以直接驅動發電機的方式進行實驗，在壓力範圍為4∼8kg/cm^2、搭配每轉25c.c.之液壓馬達時發電效率最高達10.34%。進一步修改後，大型油壓發電系統使用效率較高之液壓缸搭配曲軸連桿機構，位能槽重物重量可由500kg增加到1960kg，輸出液壓之壓
力最高為3.56kg/cm^2，負載使用14顆60W鎢絲燈泡組，最高可構成840W之負載。結果顯示，本大型油壓發電系統支初步效率達31.09%。

This article is focused on studying the electric generation using hydraulic pressure for the roadway system of waste energy storage and electric generation developed by CCT Laboratory in cooperation with Yeuchun green energy technology incorporated company. This system captures the waste energy of vehicles in the braking sections and stores in the energy storage system for electric generation. The system mainly consists of the piston plate, the potential energy storage, and the electricity generating apparatus, where the piston plate is built in multiple piston cylinders, which are pressed by vehicles in the braking sections to transfer and store the driving fluid in the potential energy storage. The high pressure fluid in the potential energy storage is further discharged for electric generation. This article technically discusses air and hydraulic electric generating systems integrated with different actuators. The applied air reservoir is 90596.5cm^3 and stored air pressure range 1∼8kg/cm^2, integrated with piston cylinder of piston diameter 12.5cm for electric generation and 20Omega adjustable resistance. The results show that the largest working efficiency of ca. 8.26% in the system appears at the air pressure of ca. 1.5kg/cm^2. Moreover, the small hydraulic electric generating system directly drives generator under pressure range of 4∼8kg/cm^2 integrated with hydraulic motor
of 25c.c./rev and receives the maximum working efficiency of 10.34%. The improved big hydraulic electric generating system uses the hydraulic cylinder with higher working efficiency integrated with the crank shaft. The heavy on the potential energy storage is changeable from 500kgto 1960kg. The output hydraulic pressure is 3.56kg/cm^2 and the circuit load has maximum valve of 840W combined with 14x60W light bulbs. The results show that the big hydraulic electric generating system has the preliminary working efficiency of 31.09%.
