【摘要】：閘門啟閉機(jī)對(duì)水庫排水蓄水有著重要作用,但其啟停機(jī)運(yùn)行一般需要電力驅(qū)動(dòng),這給閘門啟閉機(jī)的使用帶來了一定的限制,如對(duì)某些區(qū)域無電網(wǎng),架設(shè)電力線路成本昂貴的情況,而太陽能資源豐富,具有無污染、無區(qū)域限制等優(yōu)點(diǎn)。因此,如將太陽能作為閘門啟閉機(jī)驅(qū)動(dòng)能源,不僅可以解決閘門啟閉機(jī)在無市電供應(yīng)的情況下的供電問題,而且有利于擴(kuò)大啟閉機(jī)在水利方面的使用范圍,提高水利資源的利用率。本文通過對(duì)太陽能閘門啟閉機(jī)系統(tǒng)的功能要求和控制機(jī)理分析,在現(xiàn)有研究成果的基礎(chǔ)上,對(duì)閘門啟閉機(jī)驅(qū)動(dòng)系統(tǒng)總體方案、中小型閘門啟閉機(jī)參數(shù)要求、太陽能電池的輸出功率影響因素、優(yōu)化MPPT控制策略、無刷直流電機(jī)驅(qū)動(dòng)控制策略等進(jìn)行了系統(tǒng)研究。首先建立了太陽能電池輸出特性數(shù)學(xué)模型,對(duì)各種傳統(tǒng)最大功率點(diǎn)跟蹤方法進(jìn)行了分析,提出基于數(shù)據(jù)采集的變步長(zhǎng)增量電導(dǎo)法,并進(jìn)行仿真驗(yàn)證控制算法的可行性和有效性。然后選定具有功率密度大、效率高、調(diào)速性能和起動(dòng)性能優(yōu)良的永磁無刷直流電機(jī)作為太陽能閘門啟閉機(jī)的驅(qū)動(dòng)電機(jī)。為實(shí)現(xiàn)永磁無刷直流電機(jī)定子繞組正確換相,采用改進(jìn)型線反電勢(shì)過零檢測(cè)技術(shù)。同時(shí)為解決功率器件產(chǎn)生高頻干擾的問題,選用二階有源濾波電路進(jìn)行濾波處理。最后為驗(yàn)證無位置傳感器控制算法控制效果,用數(shù)字信號(hào)處理器TMS320F2812作為電機(jī)驅(qū)動(dòng)控制芯片,進(jìn)行硬件電路設(shè)計(jì),建立無刷直流電機(jī)驅(qū)動(dòng)控制系統(tǒng),實(shí)現(xiàn)電機(jī)速度、電流雙閉環(huán)控制,實(shí)驗(yàn)表明:本文采用的線電勢(shì)過零檢測(cè)技術(shù),使無刷直流電機(jī)具有良好的運(yùn)行性能。
[Abstract]:Gate hoist plays an important role in reservoir drainage and storage, but its start-up and shutdown generally need to be driven by electric power, which brings some restrictions to the use of gate hoist, such as no power grid in some areas. It is very expensive to set up power lines, but solar energy is abundant, no pollution, no area restriction and so on. Therefore, for example, solar energy is used as the driving energy of gate hoist. It can not only solve the power supply problem of gate hoist without electricity supply, but also expand the scope of application of the hoist in water conservancy. Through the analysis of the function requirements and control mechanism of the solar gate hoist system, based on the existing research results, the overall scheme of the gate hoist drive system is proposed. The parameters of the middle and small gate hoist are required, the output power of the solar cell is affected by the factors, and the MPPT control strategy is optimized. The drive and control strategies of brushless DC motor are systematically studied. Firstly, the mathematical model of solar cell output characteristics is established, and the traditional maximum power point tracking methods are analyzed. A variable step size incremental conductance method based on data acquisition is proposed, and the feasibility and effectiveness of the control algorithm are verified by simulation. Then, the method with high power density and high efficiency is selected. The permanent magnet brushless DC motor with excellent speed regulation and starting performance is used as the driving motor of the solar gate hoist. In order to realize the correct commutation of the stator winding of the permanent magnet brushless DC motor. In order to solve the problem of high frequency interference of power devices, an improved line back EMF detection technique is adopted. In order to verify the control effect of the sensorless control algorithm, the digital signal processor (TMS320F2812) is used as the motor drive control chip. Hardware circuit design, the establishment of brushless DC motor drive control system, the motor speed and current double closed loop control, experimental results show that: the linear potential zero detection technology adopted in this paper. Brushless DC motor has good performance.
