Compressor-station controls enhance flexibility
Here are computer control features of Equitable Gas' Copley Run compressor station located near Weston, W.Va. The systems facilitate local and remote control of the station by controlling the operation of four compressor units installed for field gathering, transmission, and storage service. The systems were designed to incorporate the latest control technology, provide maximum operating flexibility, require minimum operator knowledge of computer operations, and to transmit adequate operating data to, and receive commands from, Equitable's gas dispatch center in Pittsburgh. The systems utilize three programmable controllers for all permissive, sequential, protective, and inhibit logic and serve as controllers for the analog control loops as well as perform the flow-rate calculations necessary for station operations. The controllers installed are Texas Instruments Inc. Model PM 550, which use both discrete and analog input/output modules for interfacing with all field data and control functions. In addition, an on site computer has been installed for data logging and remote interface. Computer accessories include color mimic CRT (cathode-ray tube) display, keyboard entry, and hard-copy printer.
