压缩机组速度控制方案研究

摘要

以丙烯压缩机组为例，详细论述基于TRICON TS3000系统的压缩机速度控制方案，介绍了压缩机工作原理及速度控制过程。结合丙烯压缩机升速曲线，将压缩机的运行状态分成多个模式进行阐述，确定不同模式下的目标转速范围，将动态的目标值作为速度控制给定值。经过运算，控制调速器的开关大小，进而调整蒸汽量的大小，实现转速控制。%The page introduces the propylene compressor's speed control system. This paper introduces the structure of the measure speed system, the actual application of the probe, the triple control system TRICON TS3000 characteristics and working principle of pulsed module, simply introduces control object compressor working principle and speed control process, combined with compressor start up curve, describe compressor running status with multiple mode, determine the target speed limits in different mode, the output signal will control the switch, and adjust the quantity of steam to realize speed control.
