【摘要】：根據(jù)游梁式抽油機(jī)的工作特點(diǎn),開發(fā)了一套抽油機(jī)變頻節(jié)能控制實(shí)驗(yàn)平臺(tái)。該實(shí)驗(yàn)平臺(tái)基于交-直-交變換主電路,以dsPIC30F4011為控制核心,采用正弦波脈寬調(diào)制控制技術(shù)實(shí)現(xiàn)抽油機(jī)軟啟停,以及根據(jù)汲油率進(jìn)行上、下沖程變頻調(diào)速控制和"倒發(fā)電"時(shí)的饋能吸收再利用,從而達(dá)到節(jié)能增效的目的。該實(shí)驗(yàn)平臺(tái)集成了開關(guān)電源、控制單元、鍵盤顯示、檢測(cè)與保護(hù)和功率模塊驅(qū)動(dòng)等功能單元,綜合應(yīng)用了電力電子、交流調(diào)速及計(jì)算機(jī)測(cè)控等相關(guān)專業(yè)知識(shí),有助于學(xué)生深入學(xué)習(xí)和理解變頻節(jié)能技術(shù)在抽油機(jī)采油中的應(yīng)用及其控制系統(tǒng)設(shè)計(jì)方法,有利于培養(yǎng)和提高學(xué)生的工程實(shí)踐能力。
[Abstract]:According to the working characteristics of beam pumping unit, a set of experimental platform of frequency conversion and energy saving control for pumping unit is developed. This experiment platform is based on the main circuit of AC-DC-AC transform, and takes dsPIC30F4011 as the control core. The sine wave pulse width modulation control technology is used to realize the soft start and stop of the pumping unit and the oil swabbing rate is used. In order to save energy and increase efficiency, the down stroke variable frequency speed control and feed-energy absorption and reuse in backward generation can be achieved. The experimental platform integrates switch power supply, control unit, keyboard display, detection and protection and power module drive, etc., and integrates relevant professional knowledge such as power electronics, AC speed regulation and computer measurement and control, etc. It is helpful for students to learn and understand the application of frequency conversion and energy saving technology in pumping unit oil recovery and the design method of control system. It is helpful to cultivate and improve the students' engineering practice ability.
