摘要
针对油田电网中抽油机负荷特性导致的功率因数低、线损大等问题,提出了一种基于动态优化的无功补偿方案。通过分析油田电网运行负荷特点和抽油机负荷波动规律,建立了考虑经济性和安全性的无功优化数学模型。该模型以年总成本最小为目标,综合考虑了补偿设备投资、运行损耗和电压质量等因素,采用动态权重调整策略实现补偿容量的实时优化。在胜利油田S区块的应用结果表明,该方法使区域平均功率因数由0.75提升至0.92,系统线损率降低2.6百分点,年节约成本96.3万元,取得了显著的经济和社会效益。
This paper proposes a reactive power compensation scheme based on dynamic optimization.By analyzing the operational load characteristics of oilfield grids and the fluctuation patterns of pumping unit loads,a mathematical model for reactive power optimization was established.This model aims to minimize annual total costs,comprehensively evaluating factors such as compensation equipment investment,operational losses,and voltage quality.A dynamic weight adjustment strategy is employed to achieve real-time optimization of compensation capacity.Application results in Block S of Shengli Oilfield demonstrate that this method elevated the regional average power factor from 0.75 to 0.92,reduced the system line loss rate by 2.6 percentage points,and achieved annual cost savings of 963000 yuan,yielding significant economic and social benefits.
