RESEARCH CONDUCTED

  1. The Impact of Power Quality Problems in a Power Distribution System - A Case Study. This research identified and reviewed major power quality events that occur frequently, including; transient’s conditions, waveform distortion, voltage sag, voltage swell and interruptions. The research also monitored power at the Electricity Company of Ghana (ECG) using power quality analyzer through a point of common coupling of a single line supply. The research establishes significant amount of current and voltage harmonics disturbances in both the load and the supply side and confirmed the fact that, the odd harmonic orders are the most damaging. The impact of harmonics in the distribution system and consumer equipment was also discussed. Experimental results showed an alarmingly high level of harmonic distortion of more than nine percent (9.74 %) breaching the recommended IEEE standard practices, in both current and voltage at not only point of common coupling (pcc) but also at the consumer end. (2014 -2014)
  2. Performance Analysis of a Hydropower Plant In Ghana - A Case Study- Akosombo Hydropower Plant). Analysis of the effectiveness of the retrofit project at Akosombo hydropower plant and the level of improvement in the efficiency and power output of the plant was carried out by gathering and analyzing data from before and after retrofitting of the plant. Analysis of the data showed that retrofit was carried out on the generators, transformers and motor control center. Tests like hipot, doble, megger and turns ratio were performed to check the integrity of the newly installed equipment. The results of the tests indicated the fitness of some equipment to be put in service, while others were found to have faulty insulations. The performance analysis proved that the retrofit project yielded an increase in the plant's power output, from 912 MW to 1020 MW, which is an increase of 11.84 % and a plant efficiency of 98.21%. (2013 - 2013))
  3. Renewable Energy Technology in Ghana: Opportunities and Threats.This research carried out a study on renewable energy technologies (RET) in Ghana. The discussion was based on solar photovoltaics (PV) system. Some of the vital factors that have prevented the growth of a viable market for RETs using solar PV as a typical example were addressed. Adverse policy environment and lack of financing were cited as the main barriers to be surmounted. Recommendations were also made for government and all stakeholders to engage the private sector to give the RET industries a boost. The injection of an electrification fund is proposed to support grid extension to areas of proven economic potential using RET. (2012 - 2012)
  4. Causes, Effects and Mitigation of Voltage Instability in the Distribution Network of Electricity Company of Ghana (ECG) Tarkwa. This research analysed some causes and mitigation of voltage instability in the distribution network of the Electricity Company of Ghana (ECG), Tarkwa. Power World Simulator was used to evaluate short circuit Line-to-Line (L-L) faults in the network. The Simulator calculated voltage magnitude at various busbars during L-L faults with and without shunt compensation. The results were compared and analysed. It was realised that, no matter the location of faults in the network, all busbars were affected and with the injection of shunt compensators, very low voltages were increased. (2011 - 2011)
  5. Improving Power Flow in Transmission Lines Using Unified Power Flow Controller: A Case Study at Ghana Grid Company Limited, GRIDCo. This research investigated the optimal location for the placement of Unified Power Flow Controllers (UPFC) in the Ghana grid network by conducting system analysis with proposed algorithm based on Static Voltage Stability Index (SVSI) and loss sensitivity analysis using Power World Simulator software. The investigation identified fourteen (14) critical transmission lines for the placement of UPFC devices that would enhance power flow in the Ghana grid network. Typically, Akosombo to Kumasi transmission line was observed to be the most optimal location for the installation of UPFC. (2011 -2011)
  6. An Alternative Street Lighting for Umat Campus Using Light Emitting Diode (LED) Lamps.This research discussed the sustainable methods of electric energy use at the University of Mines and Technology, Tarkwa. It presented a case for the replacement of all mercury vapour lamps for street lighting on campus by LED lamps over a 15-year period. The findings revealed that LED lamps present obvious financial advantages to the University. LED lamps with their low power consumption rate reduce electricity usage, hence the reduction in electric power generation and thereby saving the amount of carbon dioxide emissions into the atmosphere. One limitation of LED lamps is their high initial cost. But within the range of other factors, LED lamps seem a superior option for mercury vapour lamp replacement. (2010 - 2010)
