针对中国石油北京调控中心不能直接远程控制长输天然气管道压缩机组而造成管道运行调整滞后的问题,以西气东输管道盐池站为例,提出了压缩机组远程控制设计原则和方案,利用现有硬件平台,开发了相应的压缩机组远程控制系统。该系统可以实现:北京调度控制中心操作员工作站可直接发出启、停以及负荷调整等命令;将压缩机组过程控制状态传输至调控中心,在调控中心人机界面显示各部分状态信号;利用现场数据计算压缩机组工作点,并在压缩机固有的流量和压比的特性曲线中显示其工作点。通过远程控制,调度人员可以及时且有重点地了解压缩机组的运行情况,并以此优化管网运行方案,快速完成整个管网调度,提升管网效率。
In order to solve the problem that the PetroChina Beijing Control Center can not directly control the long-distance natural gas pipeline compressor unit and cause lag in pipeline operation regulation, taking the Yanchi station of West-East Gas Pipeline as an example, the design principle and scheme of the remote control of the compressor unit are proposed. Platform, developed the corresponding compressor unit remote control system. The system can be realized: Beijing dispatching control center operator workstation can directly issue start, stop and load adjustment and other orders; the process of compressors group control status transmission to the control center in the control center of the man-machine interface shows the status of each part of the signal; the use of field data Compressor operating points are calculated and their operating points are displayed in the characteristic curves of the compressor’s inherent flow and pressure ratios. Through remote control, dispatchers can timely and focused understanding of the operation of the compressor unit, and thus optimize the network operation program, the rapid completion of the entire network scheduling, improve network efficiency.
