New Method for Rotor Temperature Estimation

Abstract: This paper presents a new method for observing the rotor temperature of high-power squirrel cage induction machines in measurable variables. The method is based on the fact that the rotor resistance depends on the actual rotor temperature. The main problem is to separate the changes in the rotor resistance due to temperature and skin effect. By comparing the input impedance with a kno...

Experimental verification of blade elongation and axial rotor shift in steam turbines

The experimental research of static and dynamic characteristics of rotating parts of turbomachines is a very important part of the design and verification of the machine parameters as well as optimization of their operational regimes. The described method of measuring dynamic and static characteristics, especially blade elongation and rotor axial shift, are based on the utilization of the non-c...

Steam Turbine Components and Systems

Steam turbines consist essentially of a casing to which stationary blades are fixed on the inside and a rotor carrying moving blades on the periphery. The rotor is fitted inside the casing with the rows of moving blades penetrating between the rows of fixed blades. Thus steam flowing through the turbine passes alternately through fixed and moving blades with the fixed blades directing the steam...

Avoiding Stressed-Out Steam Turbines

assembly, Pro/ENGINEER CAD geometry was imported into ANSYS Mechanical software and meshed using SOLID185 elements. Frictionless surface-tosurface contact pairs with augmented Lagrangian algorithms were created between mating surfaces. A matching node pattern was maintained at the root and slot pressure faces, where load transfers take place between the two components. As an in-house design pra...
