Step time response evaluation of different synchronous generator excitation systems

, 2016
A fast step response of an excitation system is critical for a synchronous generator in order to maintain stability under disturbances in the interconnected power grid.

Thermal Analysis of Hybrid Excitation Generator for Distributed Generation Applications

DEStech Transactions on Engineering and Technology Research, 2016
This paper presents a general thermal calculation method to analyze the thermal behaviors of hybrid excitation generators for distributed generation applications. The three-dimensional (3D) finite element method was adopted to calculate the temperature field of the air-cooled generator. The steady-state heat transfer mathematic and physical models were

Electromagnetic characteristic of a novel hybrid excitation generator for vehicles based on the field-and-circuit method

Frontiers in Mechanical Engineering
IntroductionThe electro-magnetic generator commonly used in automobiles generally has high excitation loss leading to low efficiency. And it cannot effectively provide power for the vehicle, thus shortening battery life.In order to solve the issues, a ...

High-Fidelity Model of Stand-Alone Diesel Electric Generator With Hybrid Turbine-Governor Configuration for Microgrid Studies

IEEE Access, 2022
Diesel electric generators are an inherent part of remote hybrid microgrids found in remote regions of the world that provide primary frequency response (PFR) to restore system frequency during load or generation changes.

Disturbance Rejection-Based Optimal PID Controllers for New 6ISO AVR Systems

Fractal and Fractional, 2023
In the literature, different approaches that are employed in designing automatic voltage regulators (AVRs) usually model the AVR as a single-input-single-output system, where the input is the generator reference voltage, and the output is the generator ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

FEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Epigenetic reprogramming of lineage switching in cancer

FEBS Letters, EarlyView.
Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

Nonlinear Hybrid Piezoelectric and Electromagnetic Energy Harvesting Driven by Colored Excitation

Energies, 2018
It is well known that when excited by a stochastic base acceleration, the power absorbed by a nonlinear Duffing-type piezoelectric (PE) or electromagnetic (EM) energy harvester might not be increased effectively compared to a linear one.

Characteristic analysis and optimisation of an asymmetric‐primary axial‐flux hybrid‐excitation generator for vertical‐axis wind turbines

IET Electric Power Applications, 2022
Axial‐flux wind generators have advantages of high ratio of generator diameter to generator length and high possibility of modular construction, which make them suitable for use in vertical‐axis wind turbines.
