长输气管道压缩机组原动机的选型

Selection of Compressor Unit's Mover in Gas Pipeline

通过对长距离输气管道的功耗计算和世界部分长距离输气管道的实际功耗情况介绍，提出影响功耗的关键参数的匹配问题。在此基础上根据我国长距离输气管道的具体情况（输送距离、压力、输量和系统电源情况等），提出驱动天然气压缩机组原动机的选型问题。

The matching question for the key parameters of power consumption influenced was advanced according to the power consuption caculation for gas pipeline of long distance and the actual power consumption for the part gas pipeline of long distance in the world. On this basis, the selection of gas compressor unit's mover was put forwarad in accordance with the concrete situation (transportation distance、pressure、throughput rate and system power source etc.) of gas pipeline of long distance in China.
