Analysis Of Converter Connected Synchronous Wind Turbines To Grid Disturbances., Joseph Kearney, Michael Conlon, Eugene Coyle
Analysis Of Converter Connected Synchronous Wind Turbines To Grid Disturbances., Joseph Kearney, Michael Conlon, Eugene Coyle
Conference papers
This paper investigates the performance of synchronous generators to grid voltage unbalance and grid faults. A Model of a synchronous generator with a full converter is implemented in the SimPowerSystems toolbox in Matlab/Simulink. Methods to modify the converter control schemes to improve the synchronous generator systems response to grid voltage unbalance and grid faults are investigated. Grid faults including grid voltage unbalance, and line-to-ground faults are introduced into the model at specific times to analyse the performance of the wind generation system. Improvements in the performance of the synchronous generator WECS to the grid disturbances are illustrated.
A Review Of Parallel Operation Of Active Power Filters In The Distributed Generation System, Shafiuzzaman Khan Khadem, Malabika Basu, Michael Conlon
A Review Of Parallel Operation Of Active Power Filters In The Distributed Generation System, Shafiuzzaman Khan Khadem, Malabika Basu, Michael Conlon
Conference papers
In this paper a technical review of parallel operation of Active Power Filter (APF) for harmonic power compensation in distributed generation (DG) network has been presented. Controlling methods and connection topologies with their pros and cons are described. Recent improvements in controlling and future trends for the application of APFs in distributed mode are also identified.
Observations Of The Wind Resource Across The Dublin Urban Area, Keith Sunderland, Michael Conlon, Gerald Mills, Rowan Feely
Observations Of The Wind Resource Across The Dublin Urban Area, Keith Sunderland, Michael Conlon, Gerald Mills, Rowan Feely
Conference papers
This paper presents an investigation of wind observations made at three (of a network of ten) stations in Dublin. Two of the stations are located over different parts of the urbanized landscape and one is located at Dublin Airport, which exemplifies a typical meteorological station. The purpose of the analysis is to evaluate the nature of the wind resource in the urban area. The potential output of a range of commercially available micro wind turbines at one of the stations is considered. At this location, an anemometer is mounted in a similar manner to international examples of building mounted domestic …
Does A Link Exist Between Examination Performance And Lecture Attendance For First Year Engineering Students ?, Aidan O'Dwyer
Does A Link Exist Between Examination Performance And Lecture Attendance For First Year Engineering Students ?, Aidan O'Dwyer
Conference papers
The objective of this study is to examine if a link exists between lecture attendance and examination performance of Level 7, Year 1, Electrical Engineering students at Dublin Institute of Technology in the Electrical Systems subject. Lecture attendance was monitored and analysed over four academic years (2007-8, 2008-9, 2009-10 and 2010-11). The average lecture attendance for students in the three academic years from 2007-10 was 55%, increasing noticeably in the 2009-10 academic year. A statistically significant weakly positive correlation between lecture attendance and examination performance was established. Each 10% increase in student attendance at lectures improved both Module 1 examination …

Clustering Nmf Basis Functions Using Shifted Nmf For Monaural Sound Source Separation, Rajesh Jaiswal, Derry Fitzgerald, Dan Barry, Eugene Coyle, Scott Rickard
Conference papers
Non-negative Matrix Factorization (NMF) has found use in single
channel separation of audio signals, as it gives a parts-based decom-
position of audio spectrograms where the parts typically correspond
to individual notes or chords. However, a notable shortcoming of
NMF is the need to cluster the basis functions to their sources af-
ter decomposition. Despite recent improvements in algorithms for
clustering the basis functions to sources, much work still remains to
further improve these algorithms. To this end we present a novel
clustering algorithm which overcomes some of the limitations of
previous clustering methods. This involves the use of Shifted …
