[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.
