A wavelet-based passive islanding detection technique
(
IEEE
, 2012 , Conference Paper)
Distribution power systems are radial in nature. Power flows in one direction from the utility to the load. Most protection, monitoring, and control devices are designed based on this unidirectional flow of power. Distributed ...
An improved predictive control approach for Multilevel Inverters
(
IEEE
, 2013 , Conference Paper)
This paper proposes a flexible predictive control strategy for flying capacitors based Multi-Level Inverters (MLIs). The proposed controller, applied for a Flying Capacitors Inverter (FCI) and a Modular Multilevel Converter ...
Multilevel cascaded Z source inverter for PV power generation system
(
IEEE
, 2012 , Conference Paper)
The paper investigates the use of multilevel cascaded Z source inverter (MC-ZSI) for photovoltaic (PV) power generation system. The control of the proposed system will take into account the multilevel modulation scheme and ...
Real Time Digital Feedback Control for VFD fed by cascaded multi-cell inverter
(
IEEE
, 2010 , Conference Paper)
Multi-cell inverter include an array of single-phase inverters capable of handling higher voltage ratings with lower rating power electronics devices. In this paper, a Real Time Digital Feedback Controller (RTDFBC) combined ...
Experimental photovoltaic power supply based on flying capacitors multilevel inverter
(
IEEE
, 2011 , Conference Paper)
Nowadays, a great deal of research is being carried out to utilize the solar energy effectively through power electronics converters (conditioners) to meet the increasing demand for load. In this paper, a weighted Real ...
A new PLL method for resolvers
(
IEEE
, 2010 , Conference Paper)
This paper describes a novel implementation of the classical PLL closed loop method without using VCO, DAC, counter and look-up tables. The proposed method makes use of the excitation signal of the resolver to estimate the ...
An original controller design for a grid connected PV system
(
IEEE
, 2012 , Conference Paper)
PV energy generation has been one of the most active research areas in the past decades due to its inexhaustibility and environmental-friendly aspects. However, the great deal is to utilize the solar energy effectively ...
High-reliability extra-large motor drives for oil and gas industry
(
IEEE
, 2013 , Conference Paper)
Oil and gas are the most important energy resources on the globe. They need to be transported to feed the energy to remote cities and towns. For efficient use of energy, variable frequency drives (VFD) are used in domestic ...
Enhanced Energy Extraction from a Solar Panel
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Due the movement of the sun throughout the day, the insolation level incident on the fixed panel surface varies largely. The maximum level of insolation occurs only around noon. This leads to the panel to be under-utilised. ...
Factors pertaining to academic probation of engineering students: A case study
(
Hamad bin Khalifa University Press (HBKU Press)
, 2015 , Conference Paper)
Ensuring normal progression of students isof paramount importance due to its financial implications in a higher education institution. An indicator that reflects how well an institution is doing in this respect is in the ...
