Abstract

The invention relates to a system and a method for hybrid risk modeling of turbomachinery. Systems and methods are disclosed herein for enhancing turbomachine operations. Such systems and methods include a hybrid risk model (82). The hybrid risk model (82) includes a physics-based sub model (78, 102, 206) and a statistical sub model (80, 208). The physics-based sub model (78, 102, 206) is configured to model physical components of a turbomachine (10). The statistical sub model (80, 208) is configured to model historical information of the turbomachine (10). The hybrid risk model is configured to calculate a turbomachine parameter (84, 86, 88, 202, 204, 208).

Description

technical field [0001] The subject matter disclosed herein relates to systems and methods related to risk modeling. Background technique [0002] Various systems, such as turbine systems, can include complex mechanical interrelationships between various components and subcomponents. For example, a turbine may include one or more rotor stages (eg, wheels and blades) capable of axial rotation. The individual stages of blades or vanes are capable of converting fluid flow into mechanical motion. The buckets are attached to the rotor wheel by various fasteners such as lockwires. Unfortunately, fasteners can exhibit wear (eg, stress cracking) and require repair or replacement. Similarly, other components of the turbine system may exhibit wear and require repair or replacement. Currently, manual inspection and testing procedures are used to determine whether a component should be repaired or replaced. Such inspections and tests require turbine system shutdown, which is typical...
