摘要
目前中东及非洲油气田一般自建燃气轮机电站供电,容量不大,一般几个兆瓦到上百兆瓦,孤网运行。油气田负荷主要为由异步电动机驱动的大功率泵与压缩机,单机功率可达几个兆瓦,因此系统运行条件比较严酷,特别是电动机的启动对孤网系统的冲击尤为严重,因此设计过程中需要借助仿真软件对整个系统进行仿真研究,保证系统的稳定可靠运行。
Power supply for oil gas field in Middle EAST and Africa is usually from the field self-built gas-turbine generator power plant, whose capacity is from several megawatts to hundreds of megawatts and the power plant is usually isolated operated. Main loads of oil gas field are large rating pump and compressor driven by asynchronous motor and sometimes the rating of one motor can reach several megawatts. These characteristics result in the oil gas field power system operated in harsh condition, especially when the motor is started DOL. So during engineering of the oil gas field power system, simulation study based on power system analysis software must be needed to ensure the stability and reliability.
