摘要
针对油气田采气井场供电中的电池寿命短、管理不足、数据不稳及运维成本高等问题,提出构建高可靠、智能运维的独立供电系统,以提升稳定性与智能化水平。研制了一种基于磷酸铁锂电池与远程管理平台的离网式智能光储微电网系统,集成太阳能组件、储能单元与智能监控平台。通过优化光伏发电与储能模块,系统实现发电、储能与负载的协同控制,并通过智能监控平台实时监测电池状态,支持远程数据上传与故障诊断,确保系统长期稳定高效运行。现场试验结果表明,优化系统后数据综合上线率由84.9%提升至99.2%,提高14.3个百分点;充电效率由70%提升至85%,提高15个百分点;故障响应时间由100 ms缩短至20 ms,响应时间缩短了80%,系统安全性进一步增强;备用供电时间由24 h延长至48 h,实现稳定持续供电保障;系统年均维护成本由1.5万元降低至1.275万元,降低15%。前人在光储控制与电池管理方面取得进展,但仍难满足油气井场长期稳定运行需求。本系统提升供电可靠性与智能运维能力,具备推广价值。
To address the challenges of short battery lifespan,inadequate remote management capability,unstable data transmission,and high maintenance costs in the power supply systems of gas production well sites in remote oilfields,a high-reliability off-grid intelligent photovoltaic-storage microgrid system based on lithium iron phosphate batteries and a remote management platform was developed.The system integrates solar modules,energy storage units,and an intelligent monitoring platform,and achieves coordinated control of power generation,storage,and load through the optimization of photovoltaic and battery configurations.Realtime battery status monitoring,remote data transmission,and automated fault diagnosis functions are enabled to ensure stable longterm operation under unattended field conditions.Field tests confirmed significant performance improvements after system optimization:the data connectivity rate increased from 84.9%to 99.2%(a 14.3 percentage rise),charging efficiency improved from 70%to 85%(a 15 percentage increment),fault response time was reduced from 100 ms to 20 ms(a 80%reduction),backup power duration was extended from 24 h to 48 h,and annual maintenance costs decreased by 15%from 15000 CNY to 12750 CNY.Although previous studies have advanced photovoltaic-storage control strategies and battery management techniques,most existing systems still fall short of supporting long-term reliable operation in the harsh and unattended conditions of oilfield well sites.The proposed system significantly enhances power supply reliability,operational intelligence,and economic efficiency,demonstrating strong potential for engineering application and future deployment in remote energy infrastructures.
