摘要/Abstract

摘要： “双碳”目标下，中国石油在“三北”地区开展“风光气储一体化”大基地布局，推动天然气与新能源融合发展，油田电网改造面临一系列难题和挑战。新能源电力逐步接入油田内部电网，电力系统平衡难度加大，并网电压稳定性、电网频率稳定性等受到影响，现有油田电网难以保障系统安全可靠经济运行。文章对新能源接入Q油田的电网调度自动化系统、电力智能管控平台、新能源接入适应性仿真分析等进行探索。通过完善电力调度自动化系统，实现电力系统状态估计、市场交易等功能。应用智能电力管控平台对BW区域清洁能源替代进行分析，每年可节省电费296万元，降低CO₂排放量500t。新能源接入适应性仿真分析结果说明，当新能源占比小于75%，系统电网在振荡后能够稳定状态，且燃气轮机并网点应靠近中心点母线，以防止系统电压过低及长线路所造成的振荡。

Abstract: Under the carbon peaking and carbon neutrality goals, CNPC is implementing a large layout of “wind, solar, hydro and storage integration”base in Three North Regions, promoting the integrated development of natural gas and renewables. The transformation of oilfield power grids faced a series of bottlenecks and challenges. As electricity generated by renewables gradually accesses to the internal power grid of oilfields, the difficulty of power system balance increases. Issues such as grid voltage stability and frequency stability are affected, and existing oilfield power grids struggle to ensure the safe, reliable, and economically efficient operation of the system. The article explored the grid scheduling automation system, the power intelligent control platform, and the adaptive simulation analysis of new energy integration for the Q oilfield. Through the improvement of the power scheduling automation system, functions such as power system state estimation and market transaction are achieved. The substitution of clean energy in the BW region was analyze by the application of intelligent electric power control platform. The results showed that 2.96 million yuan in electricity costs annually and 500 tons CO₂ emissions reduction can be saved. The results of the adaptive simulation analysis of new energy integration indicated that when the proportion of new energy is less than 75%, the system power grid can be stabilized after oscillation. The connection point of gas turbines to the grid should be close to the central bus to prevent low system voltage and oscillation caused by long transmission lines.
