A 1000 kW/19 200 rpm wound-rotor synchronous machine has been designed as a draft
based on 2-D transient finite-element method (FEM). The magnetic fields distribution, the …

This paper aims at investigating the use of an induction wound rotor motor to generate
voltage instead of the old diesel engines that are still used in many factories, like old cement …

This article presents the results of research on the characteristics of voltage dips occurring in
external power supply systems of 110–220 kV due to three-phase short circuits. The studies …

This paper studies asymmetrical voltage sags caused by single phase short circuits
appearing in power grids. Research defines the worst case fault conditions and shows their …

A new type of bond designed as an adapted bond is proposed. This bond can be
considered in the transition from an active bond to a bond. This approach makes it possible …

Currently, at mining enterprises, synchronous motors are used in the systems of electric
drives for compressor, fan, pumping and other installations. During the operation of …

В настоящее время на горных предприятиях нашли применение синхронные двигатели
в системах электроприводов компрессорных, вентиляторных, насосных и других …

This paper proposes a simplified but fast approach based on a Norton equivalent of wind
generators to detect undervoltage tripping of wind generators. This approach is successfully …

В работе описывается электромеханическая модель системы внешнего
электроснабжения, синхронного двигателя и системы возбуждения, составленная в …

During the last years, electric power generation was based mainly on large centralized fossil
fuelled power plants. However, nowadays and in the future, efforts are made to increase the …
