Replacement of the Fuel Control Valve on the LM2500s will improve the reliability of the units and their ability to handle increased fuel gas flows. Pressurized Control Room Various transmitters will be installed. Most will operate in conjunction with existing switches to provide a level of redundancy and to furnish the operator with a visual feedback of pressure, flow and level measurements. New RTDs will also be installed to provide better control and a visual temperature indication to the operator. An Ethernet communications module, with fiber optic capabilities, will also be supplied for connection to a station controller, which is scheduled to be installed in the future.
Reports provide diagnostic information for data logging and troubleshooting.
Real time and historical trends provide a visual representation of all analog signals. In the event of an operator interface failure, a back-up interface can be used to safely maintain operation of the machinery until the primary system can be repaired. Our priority is maximizing the availability and reliability of the customer s equipment, and keeping it current. As field changes occur, we adapt the machinery and control systems to those changes. Dresser-Rand Control Systems was awarded the project in July 1998, and plans to install the first complete control room beginning in December , 1998.
