【摘要】：现阶段的油田用电的来源,基本都源于大电网,油田微电网的设计开发还有极大的潜力,微电网是解决分布式发电并网和偏远地区或海岛供电的有效途径,具有广阔的应用前景。微电网是为整合分布式发电的优势,削弱分布式发电对电网的冲击和负面影响而提出的一种新的分布式能源组织方式和结构。它通过整合分布式发电单元与配电网,在一个局部区域内直接将分布式发电单元、电力网络和终端用户联系在一起,可以方便地进行结构和配置的优化。而且能够提高能源的利用效率,促进电网向绿色、环保、节能方向发展。综合大电网的不足以及微电网的优势,在边远油田开发设计微电源具有极高的现实价值。所以说,微电网运行将成为边远油田的有力补充和有效支撑,是未来油田电力系统的发展趋势之一。本文所设计的边远油田微电网是一类与大电网脱离孤立运行的风光柴发电的小功率微电网。根据设计的需要,之后详述了各个微电源,包括光伏电池,风力发电机,柴油发电机的基本原理,并且对各个微电源模型的数学原理进行了分析。利用它们的数学模型,用Matlab中的Simulink进行建模仿真。再根据边远油田负载的特点,选择合适的负荷,最后设计出一个结构合理,贴合实际的边远油田微电网。并对微电网的整体模型进行了仿真分析。仿真结果表明,本文所设计的微电网可以合理可靠地运行。
[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.
