【摘要】：現(xiàn)階段的油田用電的來源,基本都源于大電網(wǎng),油田微電網(wǎng)的設(shè)計開發(fā)還有極大的潛力,微電網(wǎng)是解決分布式發(fā)電并網(wǎng)和偏遠地區(qū)或海島供電的有效途徑,具有廣闊的應(yīng)用前景。微電網(wǎng)是為整合分布式發(fā)電的優(yōu)勢,削弱分布式發(fā)電對電網(wǎng)的沖擊和負面影響而提出的一種新的分布式能源組織方式和結(jié)構(gòu)。它通過整合分布式發(fā)電單元與配電網(wǎng),在一個局部區(qū)域內(nèi)直接將分布式發(fā)電單元、電力網(wǎng)絡(luò)和終端用戶聯(lián)系在一起,可以方便地進行結(jié)構(gòu)和配置的優(yōu)化。而且能夠提高能源的利用效率,促進電網(wǎng)向綠色、環(huán)保、節(jié)能方向發(fā)展。綜合大電網(wǎng)的不足以及微電網(wǎng)的優(yōu)勢,在邊遠油田開發(fā)設(shè)計微電源具有極高的現(xiàn)實價值。所以說,微電網(wǎng)運行將成為邊遠油田的有力補充和有效支撐,是未來油田電力系統(tǒng)的發(fā)展趨勢之一。本文所設(shè)計的邊遠油田微電網(wǎng)是一類與大電網(wǎng)脫離孤立運行的風光柴發(fā)電的小功率微電網(wǎng)。根據(jù)設(shè)計的需要,之后詳述了各個微電源,包括光伏電池,風力發(fā)電機,柴油發(fā)電機的基本原理,并且對各個微電源模型的數(shù)學原理進行了分析。利用它們的數(shù)學模型,用Matlab中的Simulink進行建模仿真。再根據(jù)邊遠油田負載的特點,選擇合適的負荷,最后設(shè)計出一個結(jié)構(gòu)合理,貼合實際的邊遠油田微電網(wǎng)。并對微電網(wǎng)的整體模型進行了仿真分析。仿真結(jié)果表明,本文所設(shè)計的微電網(wǎng)可以合理可靠地運行。
[Abstract]:At this stage, the sources of electric power in oil fields are basically from large power grids, and the design and development of oil field microgrid has great potential. Microgrid is an effective way to solve the problem of distributed generation and power supply in remote areas or islands. Microgrid is the advantage of integrating distributed generation. This paper proposes a new distributed energy organization method and structure which weakens the impact and negative effects of distributed generation on the power grid. It integrates distributed generation units with distribution networks and directly integrates distributed generation units in a local area. Connected with end users, the power network can easily optimize the structure and configuration. It can also improve the efficiency of energy use, promote the grid to green, environmental protection, The development of energy saving. With the shortage of large power grid and the advantages of microgrid, it is of great practical value to develop and design micro power supply in remote oil fields. Therefore, the operation of microgrid will become a powerful supplement and effective support for remote oil fields. The remote oil field microgrid designed in this paper is a kind of small power microgrid which can operate independently from the large power grid. According to the need of the design, the microgrid is described in detail. Including the basic principles of photovoltaic cells, wind turbines and diesel generators, and the mathematical principles of each micro-power model are analyzed. The Simulink in Matlab is used for modeling and simulation. According to the characteristics of remote oil field load, the appropriate load is selected, and a reasonable structure is designed. The whole model of microgrid is simulated and analyzed. The simulation results show that the microgrid designed in this paper can operate reasonably and reliably.
