Increasing market pressure for industrial turbine controls that reduce cost of installation, increase availability, and reduce overall installation and commissioning time have driven systems in a new direction. This direction is away from complex and expensive triplex or TMR (T riple M odular R edundant) systems and towards dual redundant and networked control systems. Woodward’s core fuel and combustion control is currently being used in a networked system for GE’s LM2500 aeroderivative gas turbine packages. This networked control system utilizes redundant high-speed communications from the sequencer to fuel control. Packaging I/O is also distributed over redundant communications to localize wiring. The fuel control communicates to the gas metering valves and gas turbine variable geometry servo-valves to reduce wiring and installation time. This control system utilizes simplex CPU’s to save cost and duplex hardware and communications for availability. Expansion of this to full redundant CPU processing capabilities can also be achieved to add availability with some cost tradeoff. Woodward has also applied this full redundancy concept in the commercial marine GE LM2500 package applications. In addition to using network communications the core fuel control system is in itself networked, being “package” mounted. Mounting the fuel control on the package reduces the number of field installation wire terminations and the total length of wire used between the gas turbine and the fuel control. Having the main fuel control system mounted on the package allows the control to be wired and tested at the factory rather than at site. The use of network communications in gas turbine control applications has many advantages. Reduction in overall system cost, installation and commissioning time are the main advantages to using networked controls for gas turbines. System expandability and distributed processing are other advantages. Expanding this with hardware redundancy improves availability.
