Sensitivity Analysis of Short‐Term Frequency Stability to Post‐Contingency Active Power Increase and Support Duration from Deloaded Wind Turbines

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
The growing deployment of Type‐4 wind turbine generators (WTs), driven by carbon neutrality and net‐zero policies, may challenge frequency stability in power systems. Unlike synchronous generators, WTs connected to the power system via converters do not provide inertia.

Active Power Control of Full‐Scale Converter‐Based Wind Turbine Considering Turbine Angular Velocity for Short‐Term Frequency Stability in Power Systems

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
The increasing deployment of wind turbine generators (WTs) may alter the frequency stability of power systems. Unlike traditional synchronous generators, WTs are connected to the power system through converters. Consequently, WTs cannot provide an inertia response to the power system. Nevertheless, the converters can perform rapid control.

Feasibility of Hydrostatic Transmission in Community Wind Turbines

Actuators, 2023
This study investigates the potential improvement of a community wind turbine through replacing the conventional drivetrain with a hydrostatic transmission (HST). Conventional wind turbines use a fixed-ratio gearbox, a variable-speed induction generator,

LLMs in Wind Turbine Gearbox Failure Prediction

Energies
Predictive maintenance strategies in wind turbine operations have risen in popularity with the growth of renewable electricity demand. The capacity of the strategy to predict system health, especially for the wind turbine gearboxes, is critical in reducing wind turbine operation and maintenance cost.

Effects of Bearing Configuration in wind Turbine Gearbox Reliability

Energy Procedia, 2015
AbstractThis paper investigates the impact on the reliability of different configurations of planet bearings. The studied bearings are located in the low-speed planetary stage of a wind turbine gearbox. The bearing stiffness matrix for each kind, cylindrical and tapered roller bearing (CRB and TRB), is included in the electro-mechanical drive-train ...

Empirical Physics‐Based Normal Behavior Modeling of Drive Train Temperatures With High‐Resolution Wind Turbine Operating Data

Wind Energy, EarlyView.
ABSTRACT The installed wind energy capacity increases every year. However, operation and maintenance costs still make up a considerable portion of the levelized costs of electricity. This costs can be greatly reduced by the application of suitable early fault detection methods. The supervisory control and data acquisition system of wind turbines is one

Capability and Limitations of a Tuned Mass Damper for a 15‐MW Semisubmersible Floating Wind Turbine

Wind Energy, Volume 29, Issue 11, November 2026.
ABSTRACT Large floating offshore wind turbines (FOWTs) under coupled aerodynamic and hydrodynamic loading exhibit broadband low‐frequency response in addition to the platform‐pitch resonance. Tuned mass dampers (TMDs) have been studied for a range of applications, but their net benefit under fully coupled operational conditions has not been quantified.

A Comprehensive Review of GAN‐CNN Hybrid Methods for Intelligent Fault Diagnosis of Rotating Machinery

Engineering Reports, Volume 8, Issue 10, October 2026.
This paper reviews recent advances in hybrid deep learning for intelligent fault diagnosis of rotating machinery, focusing on GAN‐ and CNN‐based architectures and their specialized variants. Hybrid GAN‐CNN methods are categorized into three groups: (1) optimized original GANs with CNN variants, (2) improved GAN architectures integrated with CNNs, and ...
