Signal monitoring and performance stability evaluation tool in a high speed optical communication network
(2016-10)
The diverse communication systems in South Africa have changed drastically over the last few years and are envisioned to continue to improve as evidenced by the deployment of high speed optical fibre networks, in both ...
Optimising Voltage Profile of Distribution Networks with Distributed Generation
(International Journal of Emerging Technology and Advanced Engineering, 2012)
Power utility companies are required to supply customers with power within specified voltage limits. Voltage rise in networks with distributed generators therefore poses a challenge. This paper presents a coordinated network ...
TRANSIENT PRESSURE WAVES IN HILLSLOPES
(2013-05)
Previous studies found that during a rainfall event, pre-event water, which exists in the
catchment before the event, may appear in significant amounts in the stream stormflow
hydrograph. Pre-event water is predominantly ...
Reducing Real and Reactive Power Losses in the Power Distribution System by DFIG Placement and Sizing Using Ordinary PSO and HGAPSO
(International Journal of Emerging Technology and Advanced Engineering, 2012)
Due to the increased importance of DFIGs in optimization of real and reactive power losses and the maintenance of voltage profile, the general methods of DG placement and sizing in the existing literature cannot be ...
Modelling Simulation and Optimal Sizing of a Hybrid Wind, Solar PV Power System in Northern Kenya
(ational Journal of Renewable Energy Research, 2016)
Solar and wind, the most abundant renewable energy resources are still expensive to deploy and are unreliable as they are intermittent. It has long been postulated in open published literature that solar and wind have ...
Voltage Stability Improvement Using the 21st Century Power Transformer
(Innovative Systems Design and Engineering, 2012)
The 21st Century Power Transformer is produced by combining modern high voltage cross-linked
polyethylene (XLPE) cable technology with conventional transformer. The technique of solid
insulation is adopted in the new dry ...
Artificial breeding of an optimized solar tunnel dryer using genetic algorithms
(International Journal of Sustainable Energy, 2011)
Studies were carried out to artificially breed an optimized solar tunnel dryer using genetic algorithms (GAs). The energy harnessed by the dryer was simulated in Visual Basic Script (Microsoft Visual Basic Script 2010TM) ...
Effects of Distributed Generation penetration on system power losses and voltage profiles
(International Journal of Scientific and Research Publication, 2013)
In present times, the use of DG systems in large amounts in different power distribution systems has become very popular
and is growing on with fast speed. Although it is considered that DG reduces losses and improves ...
Multi-Objective Environmental/Economic Dispatch Solution Using ABC_PSO Hybrid Algorithm
(International Journal of Scientific and Research Publications, 2012)
The problem of power system optimization has become a deciding factor in current power system engineering practice with emphasis on cost and emission reduction. The economic and emission dispatch problem has been addressed ...
Optimal Under - voltage Load Shedding using Cuckoo Search with Levy Flight Algorithm for Voltage Stability Improvement
(International Journal of Engineering Science Invention, 2015)
Voltage stability has become a serious threat of modern power system operation nowadays. To tackle this problem properly, load shedding is a countermeasure taken as a last resort. However, its consequences might result in ...
