大港油田人工岛能源综合利用方案

Energy Comprehensive Utilization Scheme of the Artificial Island in Dagang Oilfield

在分析滩海油田人工岛自然资源条件和能耗情况的基础上,构建了以能源综合利用为目标的新能源微电网。在该微电网系统中,实现自发电自用,余电上网。由风力发电承担微电网内基荷,微燃机根据热负荷情况调整运行状态,储能系统平抑风力发电波动并保证重要负荷持续运行。将微电网的运行控制分为四个阶段并设计了控制策略,实现并网、离网运行及切换。人工岛新能源微电网充分利用可再生能源,实现能源的综合利用,降低油气生产能耗。

On the basis of analyzing the natural resources conditions and energy consumption of beach oilfield artificial islands,a new energy micro-grid is constructed with the purpose of energy comprehensive utilization.In the micro-grid system,self-use of self-generating electricity and transmitting residual electricity to the network can be realized.The wind power generation shoulders the base-load of the micro-grid,the micro gas turbine adjusts the operating state according to the heat load condition,and the energy storage system reduces the fluctuation of wind power and ensures the continuous operation of the important load.The operation control of micro grid is divided into four stages and the control strategy is designed,and paralleled and off-grid operation and switching are realized.The new energy micro grid of artificial islands makes full use of renewable energy,realizing the comprehensive utilization of energy and reducing energy consumption of oil and gas production.
