- 摘要:
- 对于外输管道的天然气增压站，其全周期运行经济性很大程度上取决于压缩机组的运行情况。概述了影响压气站经济运行的基本要素，着重描述了管道与压气站的相互影响。通过多个典型方案的描述，指明了管道经济运行必须着重考虑负荷变化的事实。为明确管线运维中离心式压缩机的控制与运行，描述了压缩机与管道系统的内在联系，指出了影响压缩机运行点的方法。稳态运行及瞬态运行均被纳入考虑。根据给定曲线，讨论了管线输量波动情况下机组的优化，强调了驱动机选型和数量选择的重要性。
When considering gas compressor stations for pipeline projects, the economic success of the entire operation depends to a significant extent on the operation of the compressors involved. In this paper, the basic factors contributing to the economics are outlined, with particular emphasis on the interaction between the pipeline and the compressor station. Typical scenarios are described, highlighting the fact that pipeline operation has to take into account variations in load. The second part of the paper is used to address the control and operation of centrifugal compressors in pipeline service. This includes a description of the interaction between the compressor and the piping system, and methods to influence the operating point of the compressor. Steady state and transient operation is considered. Based on the demand profile, the optimization of equipment under fluctuating pipeline demand is discussed, and the importance of sizing the driver, and selecting the best number of drivers, is stressed.
