Introductionįuel systems for gas-cooled fast reactors are still in nascent stage of development. Chauvin, in Encyclopedia of Materials: Science and Technology, 2011 1. This is because the minimum limit is chosen to maintain adequate fuel flow to ensure that a flame is maintained within the gas turbine combustion system. Of the two, the maximum limit acts as a backup to temperature control and is not encountered in normal operation the minimum limit is the more important, dynamically. The output of the LVS is compared with maximum and minimum limits. Transfer from one control to another is bumpless and without any time lags. In other words, desirable operation of the MT depends on lower fuel consumption with higher output temperature and with respect to this fact, the LVS block and higher reference temperature are considered in modeling. The output of the LVS, which is called Vce, is the lowest of the three inputs, whichever requires the least fuel. These three control functions (speed governor, temperature control, and acceleration control) are all inputs to a LVS.
Why is this mechanism chosen for the fuel system? What is the role of the limiter after the LVS? Solution The outputs of the speed controller, acceleration controller, and temperature controller enter the LVS and a minimum of them are passed through the LVS. Input of the MT fuel system is supply by output of the LVS block.
