【正文】 el of scientific research in ascension, for wind power control research provides a new way. In this paper, aiming at these characteristics of uncertainty and randomness wind energy, we can use Siemens programmable controller S7200 to wind power control. The main contents include drawing the corresponding electrical schematic diagram and the flow chart, selecting the PLC and electrical ponents, turbine startup control, yaw control, temperature control, transformer control and so on. In this paper, it gives detailed explanation of the control principle and the function of each module and control program. Finally, it needs testing and simulation, using of STEP7Micro/WIN32 programming software for the PLC program debugging, simulation and online diagnosis and so on, so that the simulation results meet the design requirements. Key words： wind power generation。針對(duì)風(fēng)能具有隨機(jī)性、不確定性的特點(diǎn)， 本文 用西門子可編程控制器 S7200 來對(duì)風(fēng)力發(fā)電進(jìn)行控制。 涉密論文按學(xué)校規(guī)定處理。對(duì)本文的研究做出重要貢獻(xiàn)的個(gè)人和集體，均已在文中以明確方式標(biāo)明。對(duì)本研究提供過幫助和做出過貢獻(xiàn)的個(gè)人或集體，均已在文中作了明確的說明并表示了謝意。盡我所知，除文中特別加以標(biāo)注和致謝的地方外，不包含其他人或組織已經(jīng)發(fā)表或公布過的研究成果，也不包含 我為獲得 及其它教育機(jī)構(gòu)的學(xué)位或?qū)W歷而使用過的材料。除了文中特別加以標(biāo)注引用的內(nèi)容外，本論文不包含任何其他個(gè)人或集體已經(jīng)發(fā)表或撰寫的成果作品。本人授權(quán) 大學(xué)可以將本學(xué)位論文的全部或部分內(nèi)容編入有關(guān)數(shù)據(jù)庫(kù)進(jìn)行檢索，可以采用影印、縮印或掃描等復(fù)制手段保存和匯編本學(xué)位論文。隨著科技的不斷進(jìn)步 ，計(jì)算機(jī)和可編程控制的科研水平在提升， 這 對(duì)于風(fēng)電 控制 的 研究 又提供了 新的途徑。 最后進(jìn)行相關(guān)調(diào)試 和仿真， 利用 STEP7Micro/WIN32編程軟件對(duì) PLC 程序進(jìn)行調(diào)試、仿真運(yùn)行和在線診斷等，使仿真結(jié)果滿足設(shè)計(jì)要求。 temperature control IV 目 錄 國(guó)內(nèi)發(fā)展?fàn)顩r .................................................................................................................. 2 國(guó)外發(fā)展?fàn)顩r .................................................................................................................. 3 風(fēng)輪及其組件 .................................................................................................................. 6 機(jī)艙及其組件 .................................................................................................................. 7 塔架部件 .......................................................................................................................... 8 控制系統(tǒng) .......................................................................................................................... 8 風(fēng)速和風(fēng)能 ...................................................................................................................... 9 系統(tǒng)整體設(shè)計(jì) ................................................................................................................ 10 具體模塊設(shè)計(jì) .................................................................................................................11 I/0 地址分配 ................................................................................................................... 19 PLC 的選型 ..................................................................................................................... 19 其他器件的選型 ............................................................................................................ 20 PLC 的基本結(jié)構(gòu) ............................................................................................................. 22 PLC 的工作原理 ............................................................................................................. 23 PLC 的特點(diǎn) ..................................................................................................................... 23 PLC 的應(yīng)用 ..................................................................................................................... 24 發(fā)電機(jī)啟動(dòng)程序 ............................................................................................................ 24 偏航控制程序 ................................................................................................................ 26 摘 要 ........................................................................................................................................
