Traditional ac motor speed control system is with the method of rotor loop series resistance change speed, low speed with load capacity, low efficiency, plex operation and have the characteristics of electrical the continuous development of power electronics technology and control theory now, the second half of the 1980 s, the developed countries such as America, Japan, Germany, England VVVF inverter has been put into market and extensive application of implementation of ac motor frequency control of motor speed, so that the ac motor have greater speed range and good performance at low speed, smooth realization of ac motor speed control, solves the problems of traditional motor speed (Programmable Logic Controller, Programmable Logic Controller) control unit can work in harsh environments to remote control of the motor, to realize intelligent control of variable frequency speed regulation system, makes the speed regulation system performance more superior, meet the needs of the modern industrial production. This topic design based on PLC can inverter threephase asynchronous motor speed control system, PLC programming language, realizes the threephase asynchronous motor and reversing is to put as a PLC controller to control frequency converter, the plete motor starting, braking, acceleration, deceleration, and other functions, this pared to previous relay control, not only fast response, high reliability, and strong adaptability, easy to modify.Key words: asynchronous motor。本課題設(shè)計(jì)了基于PLC的可逆變?nèi)喈惒诫姍C(jī)調(diào)速系統(tǒng),采用PLC編程語(yǔ)言,實(shí)現(xiàn)三相異步電動(dòng)機(jī)的正反轉(zhuǎn)控制。隨著電力電子技術(shù)及現(xiàn)在控制理論的不斷發(fā)展,20世紀(jì)80年代后半期開(kāi)始,美、日、德、英等發(fā)達(dá)國(guó)家的VVVF變頻器已投入市場(chǎng)并廣泛應(yīng)用,實(shí)現(xiàn)了對(duì)交流電動(dòng)機(jī)的變頻調(diào)速,從而使交流電機(jī)有更大的調(diào)速范圍和良好的低速性能,實(shí)現(xiàn)交流電動(dòng)機(jī)的平滑調(diào)速,解決了傳統(tǒng)電機(jī)調(diào)速的諸多問(wèn)題。從而對(duì)交流異步電動(dòng)機(jī)的速度提出了更高的要求,希望一臺(tái)電機(jī)在運(yùn)行過(guò)程中,可以實(shí)現(xiàn)運(yùn)行速度的大小,轉(zhuǎn)動(dòng)方向等調(diào)節(jié),并能快速調(diào)整,波動(dòng)小,穩(wěn)定運(yùn)行。(保密的畢業(yè)設(shè)計(jì)(論文)在解密后適用本授權(quán)書(shū)) 畢業(yè)設(shè)計(jì)(論文)作者簽名: 指導(dǎo)教師簽名:簽字日期: 年 月 日 簽字日期: 年 月 日摘要摘 要交流異步電動(dòng)機(jī)是現(xiàn)代生產(chǎn)中最重要的拖動(dòng)設(shè)備之一,因其價(jià)格低廉、經(jīng)久耐用、維修容易等優(yōu)點(diǎn)而得到了廣泛應(yīng)用。畢業(yè)設(shè)計(jì)(論文)作者簽名: 日期: 年 月 日畢業(yè)設(shè)計(jì)(論文)版權(quán)使用授權(quán)書(shū)本畢業(yè)設(shè)計(jì)(論文)作者完全了解學(xué)院有關(guān)保留、使用畢業(yè)設(shè)計(jì)(論文)的規(guī)定,同意學(xué)校保留并向國(guó)家有關(guān)部門(mén)或機(jī)構(gòu)送交設(shè)計(jì)(論文)的復(fù)印件和電子版,允許設(shè)計(jì)(論文)被查閱和借閱。對(duì)本文的研究作出重要貢獻(xiàn)的個(gè)人和集體,均已在文中以明確方式表明。華東交通大學(xué)理工學(xué)院Institute of Technology.
