Estimation of inherent governor dead-band and regulation using unscented Kalman filter [PDF]
, 2017 The inclusion of the governor droop and dead-band in dynamic models helps to reproduce the measured frequency response accurately and is a key aspect of model validation.

Multi‐Agent Method Based H∞ Supplementary Turbine/Governor Control to Enhance Power System Stability
IEEJ TRANSACTIONS ON ELECTRICAL AND ELECTRONIC ENGINEERING, 2019 The stability of a power system has always been of concern. Now, wide‐area measurement systems are used widely. In this paper, we focus on supplementary turbine/governor control to enhance the stability of a power system with wide‐area measurement ...

Advanced Engineering Materials, EarlyView.Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Performance Comparison between Steam Injected Gas Turbine and Combined Cycle during Frequency Drops
Energies, 2015 Single-shaft gas turbine and its cycles are sensitive to frequency drops and, therefore, sudden change loads or large frequency dips might affect their stability.
