【摘要】：隨著能源危機(jī)和環(huán)境危機(jī)的日益加劇,世界各國(guó)都開(kāi)始關(guān)注清潔能源的發(fā)展和可再生能源的利用,以風(fēng)能和太陽(yáng)能為代表的分布式能源已逐漸成為學(xué)術(shù)界和工業(yè)界的研究熱點(diǎn)[1-2]。 但由于分布式發(fā)電空間分布的廣泛性和時(shí)間分布的隨機(jī)性,當(dāng)分布式發(fā)電滲透率逐漸升高時(shí),現(xiàn)有的電力系統(tǒng)在結(jié)構(gòu)和設(shè)計(jì)理念上都面臨著很大的挑戰(zhàn)。為解決這一實(shí)際問(wèn)題,美國(guó)學(xué)者于本世紀(jì)初首先提出了微網(wǎng)的概念。近年來(lái),對(duì)微網(wǎng)的研究已成為國(guó)內(nèi)外電氣工程領(lǐng)域的一個(gè)熱點(diǎn)問(wèn)題[3-5]。本論文基于直流架構(gòu)的微網(wǎng)系統(tǒng),主要研究用于直流微網(wǎng)系統(tǒng)的全功率風(fēng)力發(fā)電控制策略、高增益光伏接入拓?fù)湟约跋到y(tǒng)控制與能量管理機(jī)制。 1.在直流微網(wǎng)系統(tǒng)風(fēng)力發(fā)電單元,本論文利用反電勢(shì)估算法原理,實(shí)現(xiàn)了基于內(nèi)置觀測(cè)器的永磁電機(jī)位置估測(cè)矢量控制策略。在此基礎(chǔ)上采用風(fēng)機(jī)內(nèi)在功率特性MPPT策略,實(shí)現(xiàn)了最大風(fēng)能捕獲和功率管理,并利用李雅普諾夫第一定理證明了這種策略在整個(gè)工作范圍內(nèi)的穩(wěn)定性。同時(shí),搭建了一套5kW永磁電機(jī)實(shí)驗(yàn)測(cè)試平臺(tái),對(duì)此控制策略的有效性進(jìn)行了實(shí)驗(yàn)驗(yàn)證。 2.在直流微網(wǎng)系統(tǒng)光伏發(fā)電單元,在總結(jié)現(xiàn)有高增益光伏接入拓?fù)涞幕A(chǔ)之上,提出了一種基于耦合電感倍壓結(jié)構(gòu)的有源箝位Boost高增益變流器拓?fù)浣Y(jié)構(gòu)。利用耦合電感倍壓結(jié)構(gòu)引入了一個(gè)新的升壓控制自由度,實(shí)現(xiàn)了在常規(guī)占空比條件下的高升壓。同時(shí),又利用耦合電感中的原邊漏感實(shí)現(xiàn)了主開(kāi)關(guān)管的ZVS軟開(kāi)通。實(shí)現(xiàn)了將光伏組件輸出的較低直流電壓高效率地提升至滿足并網(wǎng)單元需求的直流母線電壓的轉(zhuǎn)換任務(wù)。在實(shí)驗(yàn)室制作了一臺(tái)實(shí)驗(yàn)樣機(jī),驗(yàn)證了此新型變流器在光伏發(fā)電應(yīng)用場(chǎng)合的有效性。 3.根據(jù)直流微網(wǎng)系統(tǒng)的控制要求,本論文選擇層次控制為整個(gè)系統(tǒng)的控制架構(gòu)方案,并相應(yīng)提出了變流器控制層,母線控制層以及調(diào)度管理層的層次控制結(jié)構(gòu)。在變流器控制層中,為各變流器建立了簡(jiǎn)化模型。在母線控制層中,介紹了系統(tǒng)中各個(gè)單元模塊的控制算法,以及根據(jù)母線電壓協(xié)調(diào)各單元運(yùn)行的機(jī)制,保證系統(tǒng)穩(wěn)定運(yùn)行。最后,在實(shí)驗(yàn)室搭建了一套直流微網(wǎng)測(cè)試平臺(tái),通過(guò)多組實(shí)驗(yàn)驗(yàn)證了理論分析的正確性和可靠性。
[Abstract]:With the increasing of energy crisis and environmental crisis, countries all over the world begin to pay attention to the development of clean energy and the use of renewable energy. Distributed energy, represented by wind and solar energy, has gradually become a hot research topic in academia and industry. [1-2]. However, due to the spatial distribution of distributed generation and the randomness of time distribution, when the permeability of distributed generation increases gradually. The existing power system is facing great challenges in structure and design concept. In order to solve this practical problem, American scholars first put forward the concept of microgrid at the beginning of this century. The research of microgrid has become a hot issue in the field of electrical engineering at home and abroad
[In this thesis, the full power wind power generation control strategy, high gain photovoltaic access topology, system control and energy management mechanism for DC microgrid systems are studied. 1. In the wind power generation unit of DC microgrid system, the principle of inverse EMF estimation is used in this paper. The position estimation vector control strategy of permanent magnet motor based on built-in observer is realized, and based on this, the maximum wind energy capture and power management are realized by adopting the inherent power characteristic of fan MPPT strategy. The stability of the strategy in the whole work range is proved by using Lyapunov's first principle. At the same time, a test platform of 5kW permanent magnet motor is built. The effectiveness of the control strategy is verified experimentally. 2. On the basis of summarizing the existing high gain photovoltaic access topology in DC microgrid system photovoltaic power generation unit. An active clamped Boost high gain converter topology based on coupled inductance doubling structure is proposed. A new boost control degree of freedom is introduced by using the coupled inductance double voltage structure. At the same time, the high voltage booster is realized under the condition of normal duty cycle. The ZVS soft switch of the main switch is realized by using the original side leakage inductance in the coupling inductor, and the conversion of the lower DC voltage output from the photovoltaic module to the DC bus voltage which meets the needs of the grid-connected unit is realized with high efficiency. A prototype was made in the laboratory. The validity of the new converter in photovoltaic applications is verified. 3. According to the control requirements of DC microgrid system, this paper selects hierarchical control as the control architecture of the whole system, and puts forward the converter control layer accordingly. In the converter control layer, a simplified model is established for each converter. In the bus control layer, the control algorithm of each unit module in the system is introduced. And according to the bus voltage coordination of each unit operation mechanism to ensure the stable operation of the system. Finally, a set of DC microgrid test platform is built in the laboratory. The correctness and reliability of the theoretical analysis are verified by many experiments.
