[[alternative]]The Study of Hybrid Wind Power and Solar Power for Water Heater

碩士電機工程學系[[abstract]]近年來，綠色能源的議題已經被人們熱烈討論，而如何以最經濟方式取得熱水，除了古老的木材燒水，目前大約可分為電熱器、瓦斯與太陽能熱水器加熱。但是木材燒水有許多不便性，瓦斯燃燒不完全會產生一氧化碳等，相較之下太陽能熱水器具備節能省碳之特性，成了未來發展之主流。 目前太陽能熱水器系統，在連續陰雨天時太陽能集熱板因無日照致無法發揮效用，於是另有加入加熱棒方式，作為輔助加熱之用。惟加熱棒的使用耗電量亦高，特別在雨季多的地方，加熱棒的耗電量不容小覷。 本研究主要在降低加熱棒的耗電量，提出以風力發電模組配合傳統太陽能熱水器，利用風力發電機轉換風能為電能，對加熱棒供給電能，以進行熱水加熱。由於風力發電模組可將大自然的風能轉變成電能對加熱器供電加熱，使加熱器加熱儲水器之儲水，實際使用熱水時不足之熱能再以市電瞬間補足，藉以降低加熱器對市電電源的依賴，減少市電的使用需求。[[abstract]]ABSTRACT In recent years, green energy related issues have been discussed for a long time. And, how to obtain hot water economically is one of the issues. Except traditional firewood method, there are electric-heater, gas, and solar water heater to obtain hot water. However, the firewood method is inconvenient; and incomplete gas heating releases carbon monoxide. Comparing with other methods, solar water heater with energy-saving and carbon reduction characteristics is therefore the mainstream of future development. The present solar water heater system can not effectively collect enough solar energy to heat water during continuous cloudy and rainy days. To solve this problem, an electric-heater stick is installed in solar water heater system to facilitate the heating. However, this increases the energy consumption from grid-source. Especially, in the rainy season, the power consumption of the heater should not be underestimated. The main purpose of this research is to apply wind power generator module to the present solar water heater. This wind power generator module supply energy to another auxiliary electric-heater to heat water in the storage-tank. While the heat is not enough, instant energy can be supplied by the electricity. This module decreases the dependence of the grid-source and reduces the demand of electricity
