摘要
针对油田计量间屋顶结构多样、环境恶劣导致的分布式光伏应用难题,通过建立结构承载力动态评估模型,结合盐雾加速腐蚀实验与纳米涂层技术,开发了适配砖混/钢制橇装屋顶的光伏系统。采用倾角优化算法与LCL滤波器,解决了风振(风速小于或等于28 m/s)、硫化氢腐蚀等特殊工况问题,并创新性地引入碳交易收益模型提升经济性。砖混平顶光伏系统实际发电量达理论值89.3%,钢制屋顶风载振动加速度控制在0.15g以内,全生命周期碳减排量达789~859 tCO_(2)。两种光伏发电方案的单位兆瓦初始投资为518万元~582万元,动态投资回收期6.8~9.6年。屋顶分布式光伏电站方案可为油田场景提供兼顾安全性与经济性的光伏建设范式,建议后续开展光储氢一体化研究以提升微电网适配性,同时关注政策波动对投资收益的影响机制。
In view of the distributed photovoltaic application problems caused by the diverse structures and harsh conditions of the rooftop of oilfield measurement stations,the photovoltaic systems that are adaptable to brick-concrete or steel skid-mounted roofs are created through developing the dynamic structural load assess-ment model and combining salt spray corrosion tests and nano-coating technology.By adopting the inclination optimization algorithms and LCL filters,the special working conditions containing wind vibration(wind speed≤28 m/s)and hydrogen sulfide corrosion are solved,and the carbon trading revenue model is innova-tively introduced to enhance the economy.The actual power generation of the brick-concrete flat-top photovolta-ic system reaches 89.3%of theoretical value.The wind-borne vibration acceleration of the steel roof is con-trolled within 0.15g,and the carbon emission reduction of the whole life cycle reaches 789~859 tCO_(2).The initial investment per megawatt of two photovoltaic power generation schemes is 5180000 yuan to 5820000yuan,and the dynamic investment recovery period is 6.8 years to 9.6 years.The rooftop distributed photovoltaic power stations provides a safe and economical photovoltaic implementation model for oilfields,with future research recommended for photovoltaic-storage-hydrogen integration to enhance micro-grid compatibility.At the same time,the attention is paid to the mechanisms by which the policy fluctuations affect investment returns.
