小型風力供電系統設計畢業論文(已修改)

　

【正文】 （摘 要風能作為一種清潔的可再生能源越來越受到人們的重視，風力發電也逐漸成為了時下的朝陽產業。本論文詳細闡明了小型獨立風力供電系統的設計方案，對風力發電機進行了簡單的介紹和對蓄電池的充、放電做了深入的研究。本文的題目是小型風力供電系統的設計，要求是可以在連續兩天無風的情況下持續提供 10w 的 12v 的直流電，并有缺電報警和輸出保護功能。本文提出的解決方案為，風力發電機發出的電，通過 DC—DC 變換為需要的標準直流電，并且考慮到風力的不穩定性，在系統中并入蓄電池組，通過控制電路的監控實現系統的控制，保證系統在風能充足時可蓄能，在兩天無風時可以連續為負載供電。系統的運行狀況主要采用單片機控制。本論文的重點在于控制電路的設計，并對各種不同風力情況下系統的運行狀況進行了全面而嚴謹的分析。關鍵詞：發電機、DCDC 變換、蓄電池、單片機本科畢業設計說明書中 文 題 目 : 小型風力供電系統的設計AbstractAs a clean and renewable energy, Wind power has aroused more and more attention and gradually bee a sunrise industry nowadays。This paper spells out the small independent wind power system design, wind generators on a simple presentation and the battery charge and discharge depth study done。This topic is smallscale wind power system design, requirements for two consecutive days in the case of no wind continues to provide the 12v 10w DC, and lack of electricity and output protection alarms， The proposed solution, given the power of wind generator, through the DCDC conversion for the required standard DC，And taking into account the instability of the wind adding batteries in the system , control circuit monitoring and control by the control system to ensure the system can be sufficient in wind energy storage, in the days when no wind is a continuous load.。Health of the system mainly uses the microcontrollerThis paper focuses on the design of the control circuit, and a variety of wind conditions in the operational status of the system conducted a prehensive and rigorous analysis。Keywords: generator, DCDC conversion, battery, MCU目錄第一章 緒論 ..............................................................................................................................1 課題的目的和意義 ..............................................................................................................1 風力發電的優點 ..................................................1 課題的目的和意義 ................................................2 風力發電概述 ......................................................................................................................2 國外風力發展 ....................................................2 國內風力發電的基本情況 ..........................................3 風力發電的特點 ..................................................3 本文的主要研究內容 .........................................................................................................3第二章小型風力發電系統的基本組成 ....................................................................................5 風力發電機組 .....................................................................................................................5 小型風力發電機的分類 ............................................5 小型風力發電機的結構 ............................................6 整流器 .................................................................................................................................7 DCDC 變換器 ....................................................................................................................8 蓄電池 .................................................................................................................................9 蓄電池的工作原理 ................................................9 影響鉛酸蓄電池壽命的因素 .......................................11 閥控式鉛酸蓄電池的使用原則 .....................................12 鉛酸蓄電池的充電方法 ...........................................12 控制器 ...............................................................................................................................13 控制器的作用 ...................................................13 控制器的類型 ...................................................13 控制器的其他功能 ...............................................14第三章 供電系統電路的硬件設計及及軟件實現 ................................................................14 發電機、蓄電池的選擇 ...................................................................................................14 設計實例 ...........................................................................................................................15 DCDC 變換芯片及單片機的選擇 ..................................................................................16 DCDC 芯片的選擇 ...............................................16 單片機的選擇 ...................................................17 控制器電路圖的設計 .......................................................................................................21 .......................................................21 系統電路圖組成 .................................................21 統軟件的實現 ....................................................................................................................24第四章 結論 ..............................................................................
