Active hybrid bearings as mean for improving stability and diagnostics of heavy rotors of power generating machinery

IOP Conference Series: Materials Science and Engineering, 2020
Abstract The article describes a theoretical study of basic features of active hybrid bearings used as supports for heavy energy-generating machines equipment, primarily turbine generators and their turbines. Due to the adjustable oil supply pressure and using a controller of a rotor position AHB reduces its vibration level.

Estimation of Daily Photovoltaic Power One Day Ahead With Hybrid Deep Learning and Machine Learning Models

Energy Science & Engineering
In this study, hybrid LSTM‐SVM and hybrid LSTM‐KNN models were developed to predict hourly PV power one day ahead. The performances of these hybrid models were compared with K‐nearest neighbors (KNN), long short‐term memory (LSTM), and support vector ...

A reliable and straightforward index to avoid nuisance trip of the conventional Z‐based loss‐of‐field relay in synchronous generators

IET Generation, Transmission & Distribution, 2022
The conventional impedance (Z)‐based relay which is the well‐known relay to preserve the power plant's synchronous generator (PPSG) against loss of field (LOF) accident may fail during some stable power swing (SPS); on the other hand, most of the ...

The Impact of “Soft Power” Means on the Hybridization of Modern Wars

Metafizika Journal
Modern wars are experiencing a period of serious transformation. The dominance of “hard power” inherent in classical wars has come to an end. This is due to the increased influence of non-military threats on global security. In this case, the increasing role of information, economic, demographic, cultural, political, financial and other factors, along ...

What is Power Sharing? Its Meaning and Three Types: Consociationalism, Centripetalism, and Hybrid Power Sharing

Studia Polityczne, 2018
In this article the author analyzes the term “power sharing” (PS) in the context of power exercised within a state. He first examines the term in the very general sense, in which it can be applied to all types and dimensions of power sharing between various groups and institutional entities.
