太阳能发电系统在延长油田的应用

摘要

太阳能发电系统可分为并网式发电和离网式发电两种,并网式发电是将太阳能发出的电能并入电网,离网式发电则为独立的发电系统.延长油田采气井场远离地方电网,如采用常规供电线路的供电方式,工程造价高昂,采用太阳能独立发电系统供电,不仅可节约大量工程投资,还可减免供电线路的运行维护工作.通过合理配置太阳能电池方阵容量、蓄电池容量、太阳能充电控制器容量,可保证太阳能发电系统持续稳定地运行,实现经济效益最大化.%Solar power generation system can be divided into two kinds, namely grid connected power generation and off grid power generation. Grid connected power generation merge the power of the solar energy into the power grid, while off grid power generation is an independent power gen-eration system. Gas production well sites in Yanchang Oilfield are far away from the local power grid, so if the conventional power supply line is used to supply power, the project cost is high. If the solar independent power supply system is used to supply power, a large amount of investment can be saved and operation and maintenance tasks of power lines can be reduced.Through the reasonable configura-tion of the capacity of the solar power battery matrix, the storage battery capacity, the solar energy charging controller and other major equipments of the system, the solar power generation system can be guaranteed to operate continuously and steadily,thus achieving maximum economic benefits.
