【摘要】：隨著可持續(xù)發(fā)展戰(zhàn)略和建設(shè)能源節(jié)約型社會觀念的深入人心,風能和太陽能等新能源的利用規(guī)模也越來越大,特別是在我國偏遠的山區(qū)、草原以及孤島等不通市電的地區(qū)。科技的進步和人們用電要求的不斷提高,使得常用的單一提供直流電或者交流電的直流風光互補控制器和逆變器,顯然很難滿足使用安全、操作簡便、功能齊全的要求。因此,研制出一種既能供低壓直流負載和標準市電交流負載同時使用,又能改善風能和太陽能利用效率且人機交互簡便地風光互補逆控一體機,具有十分重要的市場價值和應(yīng)用前景。 本文以小功率的風光互補逆控一體機為設(shè)計目標,采用TI公司的DSP芯片TMS320F2812作為控制中心,在Altium Designer Winter09里完成逆控一體機的硬件電路設(shè)計,使用C語言在集成開發(fā)環(huán)境Code Composer Studio里進行軟件編程,實現(xiàn)對風光互補逆控一體機的控制,設(shè)計了一個體積小、直流充／放電穩(wěn)定、交流輸出波形特性好、能源利用率和安全性能高、人機交互友好的風光互補逆控一體機。 本設(shè)計首先通過對傳統(tǒng)逆控一體機涉及到的風光互補發(fā)電系統(tǒng)和逆變系統(tǒng),及二者的核心控制最大功率點跟蹤MPPT和SPWM逆變技術(shù)進行了簡單的介紹,引出了本設(shè)計逆控一體機的總體結(jié)構(gòu),并分別對構(gòu)成本設(shè)計逆控一體機的風光互補控制器和逆變器的結(jié)構(gòu)和工作原理進行了闡述,給出了本設(shè)計逆控一體機的主要外圍器部件的選型和相關(guān)參數(shù)。 其次,本文詳細論述了逆控一體機的硬件電路實現(xiàn)——主電路拓撲設(shè)計和輔助模塊化電路設(shè)計。逆控一體機的主電路設(shè)計按照電能的流動方向依次展開,逆變電路的設(shè)計放棄技術(shù)較為成熟先直流高頻升壓再逆變的逆變策略,嘗試采用低壓逆變再工頻升壓的方式。最后詳細闡述了逆控一體機中控制器的最大功率點跟蹤MPPT、電流電壓模糊自整定PID控制和逆變器中SPWM的具體實現(xiàn)方法,給出了軟件流程圖。 根據(jù)上述設(shè)計,本文進行了樣機的制作并開發(fā)了一套測試平臺對樣機進行了實際測試驗證,測試驗證結(jié)果表明,本設(shè)計的逆控一體機控制器樣機直流負載部分運行優(yōu)良,逆變器部分正弦波輸出電壓與頻率穩(wěn)定,帶載能力穩(wěn)定,達到了設(shè)計目標。顯然,應(yīng)用本設(shè)計方法,可大大降低此類設(shè)備的電路復(fù)雜度和生產(chǎn)成本,提高應(yīng)用此類設(shè)備的太陽能和風能的利用效率,解決了由風光互補控制器和逆變器二者連接應(yīng)用所帶來的使用復(fù)雜、安全性低、生產(chǎn)成本較高的問題,從而也延長了產(chǎn)品的使用壽命。
[Abstract]:With the sustainable development strategy and the idea of building energy-saving society, the scale of new energy, such as wind energy and solar energy, is becoming larger and larger, especially in the remote mountainous areas, grasslands and isolated islands in China. With the development of science and technology and the continuous improvement of people's demand for electricity, it is obviously difficult to meet the requirements of safe operation, simple operation and complete function because of the common single DC wind complementary controller and inverter which provide DC or AC power. Therefore, we have developed a new integrated wind and solar power system, which can be used for both low voltage DC load and standard AC load, and can improve the utilization efficiency of wind and solar energy. It has very important market value and application prospect. This paper takes the small power wind complementary inverse control integrated computer as the design goal, uses TI's DSP chip TMS320F2812 as the control center, and completes the hardware circuit design of the inverse control integrated computer in Altium designer Winter09. C language is used for software programming in Code composer Studio, which realizes the control of the wind complementary inverse control integrated computer. A small volume, stable DC charge / discharge and good AC output waveform characteristics are designed. High energy efficiency and safety performance, human-computer interaction friendly wind complementary inverse control integrated machine. This design first of all through the traditional inverse control system involved in the wind complementary generation system and inverter system, The MPPT and SPWM inverter technology of the core control MPPT and SPWM are introduced, and the overall structure of the integrated inverse control machine is introduced. The structure and working principle of the wind complementary controller and inverter which constitute the integrated inverse control machine are described respectively, and the selection of the main peripheral parts and the related parameters of the integrated inverse control machine are given. Secondly, This paper discusses in detail the realization of the hardware circuit of the integrated inverse control machine-the topology design of the main circuit and the design of the auxiliary modularized circuit. The main circuit design of the integrated inverter is carried out in turn according to the flow direction of the electric energy. The design of the inverter circuit gives up the technology of DC high frequency boost and then the inverter strategy, and attempts to adopt the low voltage inverter and the power frequency boost mode. At last, the realization methods of MPPTT, fuzzy self-tuning pid control of current and voltage and SPWM in inverter are described in detail, and the software flow chart is given according to the above design. In this paper, the prototype is made and a set of test platform is developed to test the prototype. The test results show that the DC load part of the prototype of the reverse control integrated controller is running well. The output voltage and frequency of partial sinusoidal wave of inverter are stable, and the load capacity of inverter is stable. Obviously, the application of this design method can greatly reduce the circuit complexity and production cost of such equipment, and improve the utilization efficiency of solar and wind energy. The problems of complex use, low safety and high production cost brought by the application of wind complementary controller and inverter are solved, thus prolonging the service life of the product.
