摘要: A control method and apparatus for startup of turbocompressors to avoid overpowering a driver of the turbocompressor. In a first embodiment, the control system monitors input signals from transmitters of various control inputs. When the input signals exceed threshold values, the control system begins to close the antisurge valve. In a second embodiment, the antisurge valve begins to close after a predetermined time measured from the time startup is initiated. In both embodiments, the antisurge valve continues to ramp closed until the compressor has reached its operating zone, or until the compressor's operating point reaches a surge control line, at which point the antisurge valve is manipulated to keep the compressor from surging.

摘要翻译: 一种用于启动涡轮压缩机的控制方法和装置,以避免对涡轮压缩机的驱动器施压。 在第一实施例中,控制系统监视来自各种控制输入的发射机的输入信号。 当输入信号超过阈值时,控制系统开始关闭防喘振阀。 在第二实施例中,在从启动时间开始测量的预定时间之后,防喘振阀开始关闭。 在两个实施例中,防喘振阀继续斜坡关闭,直到压缩机已经到达其操作区域,或者直到压缩机的操作点到达喘振控制线为止,此时操作防喘振阀以保持压缩机不起作用。

摘要: A control method and apparatus for critical rotational speed avoidance in a compressor-expander set in a gas refrigeration system. By varying an opening of an antisurge or recycle valve, a shaft power used by the compressor in the compressor-expander set may be varied, thereby varying the rotational speed of the compressor-expander set to move it away from its critical speed zone. Additionally, a feedforward signal may be provided by a compressor-expander set control system to cause an antisurge valve for a recycle compressor to open upon a trip or shutdown of one compressor-expander set.
