Title: Control of rotor stress within turbomachine during startup operation
Inventor: AUSTIN DANIEL FRAZER
IPC: F01D19/00
Filed: 2021-09-15
Abstract: To provide a method, a program product and a system for controlling a rotor stress within each component of a turbomachine.SOLUTION: Embodiments of the disclosure provide a method for controlling a turbine during startup. The method includes calculating predicted stress on a rotor (26) of a turbine component (48), and determining whether the predicted stress exceeds a threshold. If the predicted stress exceeds the threshold, an inlet valve (104) is adjusted to a warming position, which is less open than a minimum load position. When steam in a discharge passage (112) reaches a target pressure, an exhaust valve (110) partially closes. If a safety parameter of the turbine component (48) violates a boundary, the exhaust valve (110) partially opens while the inlet valve (104) is kept in the warming position. The predicted stress on the rotor (26) is recalculated with the inlet valve (104) being in the warming position. When the predicted stress does not exceed the threshold, the inlet valve (104) opens to at least the minimum load position.SELECTED DRAWING: Figure 4
