- PublicationDevelopment and testing of 1 kWp of floating solar platform(2020-02)Muhammad Ashhad Naim Bin Mohamad NasirEnergy generation through solar Photovoltaic is one of the best resolves to solve nowadays environmental problems. Even so, there are a few drawbacks for this alternative mainly the wide area used for farm installation and its low capacity factors compared to the other alternatives. Hence, Floating Photovoltaic (FPV) and solar tracking technologies emerge to counter the issue. A full prototype of floating solar platform is constructed and the safety factors of the platform was conducted through load testing. Using this platform, desktop study was done to investigate its approximate available installation capacity and on the other hand, the inclination study for the solar panel was done to get the best performance at University Tenaga Nasional’s lake. Under the simulation, the highest yield was obtained annually using 0 degrees’ inclination compared to 5, 10 and 15 degrees facing south. Annual yield for inclination facing east versus west was done, and the highest annual yield goes to west inclination thus proves more energy was gained after the afternoon compared to before afternoon. Last but not least, for the computational study, simulations of single axis and dual axis tracker was done in four different places. The increment of yield was calculated and the efficiency was 17.57% and 20.57% for Malaysia, 18.48% and 22.18% for Vietnam, 24.84% and 27.78% for United Kingdom and 40.43% and 56.56% for Garepdam in South Africa for single axis and dual axis solar tracking respectively. This study suggest that the solar tracking technology was more efficient at places with higher irradiation reading. Lastly, Return of Investment and payback period for the prototype was calculated using the respective simulation. ROI calculated was 11.54%, 13.04% and 14.24% for static FPV, Single axis tracking and Dual axis tracking Floating Photovoltaic (FPV) respectively. The respective payback period was 8.7 years, 7.2 years and 7.0 years respectively
48 106 - PublicationSynthesis and characterization on mechanichal behavior of YTZP with TiO2 addiion as top coat for thermal barrier coating application(2020-02)Wan Muhamad Amirul Bin Wan MuenThe world today is a modern world that races for technological and infrastructural advances in particular. Thermal barrier coating is one of the applications that encourage the development in the industry. Gas turbine blade is one of the application that applied thermal barrier coating concept. The main purposed of this coating to withstand high temperature in the system and increase the system performance. However the conventional thermal barrier coating applied in industry was YSZ. This conventional coating only can hold the system until 1200˚C only. Therefore, Y-TZP doped with TiO2 are seen to be an alternative way to replace YSZ as thermal barrier coating. Thus, a study entitled “ Synthesis and Characterization on Mechanical Behavior of Y-TZP with TiO2 addition as Top Coat for Thermal Barrier Coating Application” was done by taking Y-TZP doped with TiO2 as alternative material as top coat ceramic layer. Y-TZP was chosen because it’s the strongest ceramic material and highest flexural strength of group zirconia base. In order to implement Y-TZP doped with TiO2, the samples are fabricated into five different compositions. For the fabrication, samples mixed by ball milling process to mix the composition. Next, all samples will undergo pressing method to change into pellet form. Sintering process at 1400˚C is the next process before sintered samples undergo characterization process. SEM, EDX and XRD were involved in characterization process to evaluate morphological, elemental composition and phase of material. At the end of study, mechanical properties in term of hardness was evaluated by Brinell Hardness Test. The value obtained was compared to validate the hardness of samples.
31 7 - PublicationResearch and development(2020-02)Syed Ikmal Hakim Bin Syed IsmailNowadays, global warming and pollution are issues of great concern. The urgent need to address the issue of greenhouse gases has led to several alternative solutions to fossil fuels. Among the several renewable energies, biogas sparkles because of its various economic and environmental advantages. When compared to fossil fuels that may come from miles and miles away, biogas has the benefit of being formed often near its users thus reducing transport and handling outlays. In addition, agricultural enterprises benefit from substantial savings when fertilizing their crops by using the fertilizer produced by anaerobic digestion. Anaerobic digestion is a process which organic materials are broken down by micro-organisms without the presence of oxygen. When biogas known as a renewable energy that can be formed nearby of its users, a home biodigester was introduced. Home biodigester are also recognized as a continuous-fed system. Therefore, this project is mainly to design and develop a home biodigester where it will produce methane gas which will be used for cooking as well as electricity. Then, the biogas residue can also be used for plant fertilization. Anaerobic digestion produces two products which are digestate and biogas. This digestate also called biogas residue is a nutrient-rich biofertilizer. For this project fruit and vegetables waste are the main reactants to operate anaerobic digestion starting with horse manure as the accelerants to allow the growth of bacteria. Hence, as this home biodigester is a continuous fed system, the tank will be fed with fruits and vegetables waste everyday. All data and observation taken was auto-calculated by a website named “Biogas World” where the amount of horse manure and daily wastages were inserted thus the TS, VS and BMP values will be automatically calculated. The presence of methane produced in the DSR will be observed in daily basis.
25 73 - PublicationAnalysis Of large Area Substation Grounding Behaviour Under Transient fault Conditions For Different Lightning Parameter Models(2020-02)Abila AllakhappayeeThis thesis utilises CDEGS software to compute peak current of 30kA, 100kA with both front time and soil resistivity of 1μs, 19μs and 100Ω.m, 1000Ω.m. The simulation of different current amplitudes of 30kA and 100kA using Heidler function generated in FFTSES module with 1μs, 19μs of front time. Then in HIFREQ module a 40m X 40m and 100m X 100m grid size is constructed. Energization of generated current in FFTSES is the injected near to the centre of the grid. Then examination of safety limits for grid which are step and touch voltage being conducted. This paper also analyse the influence of lightning parameters which are peak current and front time of the wave shape. For all the case analysed it is only applicable for body weight of 50 kg in conclusion from the results obtained deduce that the soil resistivity plays a very important role to produce safe touch and step voltage. While the lightning parameter which is front time of the wave shape does not affect the safety limits which are the step and touch voltage.
56 46 - PublicationDesign Of Energy Storage Controller To Mitigate Intermittency From Solar PV(2020-02)Afiqah KamalThe growing presence of renewable photovoltaic (PV) power generation in national infrastructure leads to the continuous search for improvement to mitigate the destabilizing effects of renewable intermittency. Intermittency in solar power mainly occurs because of solar irradiance and temperature. Intermittency can lead to grid instability as well as further losses. The disruption in power generation from Renewable Energy Sources (RES) has become a key issue in the transition to renewable energy [1]. This project would concentrate on the effective incorporation of energy storage system with controller to mitigate the intermittent from solar PV. The design of the solar PV system is validated through MATLAB Simulink before intermittency problem is created. Battery energy storage with controller is proposed in this paper to solve the intermittency problem. All the simulation results are evaluated in ensuring the objectives of this project are successfully achieved.
