摘要
It is a control system for controlling a subsea gas compression system which includes a compressor (1), an electric motor (2) that drives the compressor, and at least one valve (3) to control a flow through the compressor. the control system includes an subsea control system (6 ') comprising a plurality of process sensors (8, 9, 10) for measuring compression system process parameters, a compressor controller (22) configured to generate commands control for controlling the engine and valve based on sensor process parameter measurements, and an electrical device (12?) that includes hardware and software to influence a portion of the gas compression system. the fixture is arranged to receive measurements from the process sensors and the compressor controller is integrated into the fixture. the electrical device is any one of an actuator (12?) to control valve position, a variable speed actuator (14?) to control the engine speed (2) that drives the compressor by adjusting the frequency of the power supplied to the motor, a switching apparatus (16 ') connected to the variable speed drive to turn the variable speed drive on and off, or an uninterruptible power supply to provide emergency power to the control system.
