拟议在中原油田300多公里的长距离输气管线只建一个燃气轮机压缩机增压站。如图1所示,增压站由两台航机陆用型机组WZ5G,分别带动串联的两台低、高压离心式压缩机。选用输气管线的首端压力Pg_2作为被控参数。要控制Pg_2,首先要确定在同样首端压力下,两台燃气轮机的负荷如何分配才能使总的燃料消耗量为最小,这是一个静状最优化的问题。对 It is proposed to build only one gas turbine compressor booster station in the long-distance gas pipeline of over 300 kilometers in Zhongyuan Oilfield. As shown in Figure 1, the booster station is composed of two aircraft land-based units WZ5G, which respectively drive two low and high pressure centrifugal compressors in series. Selection of gas pipeline head pressure Pg_2 as a controlled parameter. To control Pg_2, it is first necessary to determine how the load of the two gas turbines will be distributed at the same head pressure to minimize the total fuel consumption. This is a statically optimal problem. Correct
