I am currently involved in a project looking at re-wheeling a gas turbine driven centrifugal axial compressor. Cooling fans, which are to be
changed due to the increased heat load, control the compressor discharge temperature and are manually operated when required.The proposal is
to operate the cooler fans automatically under closed loop control using variable speed drives to drive the fan motors. The temperature is
to be maintained within a band of 10-30 Centigrade.
Does anyone have experience of this type of application specifically with regard to the control scheme selection, what to account for when
analysing the control loop, or any other practical guidance.
