Simulation study of automatic voltage regulator system by using PID and MRAC controller
No full textThe applications of Automatic Voltage Regulator (AVR) had been widely used in past decades. Precise and fast responsive controller is needed for AVR because most of the electrical equipment are sensitive to the voltage level. Majority of the devices that connected to the grid have its own desired voltage level, or so-called nameplated value for proper functioning. The problem arises when the voltage level fluctuates or beyond the operation limit of electrical equipment, it will affect the performance and case comes to the worst, the equipment will be damaged seriously [1]. Therefore, the demand of having precise controller is increasing lately..
Prototype development of PV powered barrier gate system
No full textNowadays we can see the development of technology rapidly increased in order to fullfill the needs of world community. Despite the rapid of this development, it required a large energy source. The most energy source that have been used around the world was fossil fuel. Energy source are divide into two categories, renewable energy and non-renewable energy. Renewable energy is the energy source that can be use continuously without limit, such as solar energy from the sun, hydropower from flowing water, wind energy, biomass from plants, and geothermal energy from heat inside the earth. Non-renewable energy is the energy source that is used for a certain period, depends on its availability and they cannot easily replenished, like fossil fuel such as petroleum product, hydrocarbon gas liquids, natural gases, coal and so on. Renewable energy and non-renewable energy sources usually act as primary energy source to produce other energy such as heat or secondary energy source such as electricity [1]. Malaysia has high potential to build a large scale of solar power due to strategic location at the equatorial region. Malaysia's climate has relatively high levels of temperature and humidity. Throughout the year, the temperature ranges between 22˚C and 33 ˚C (72-91˚F) and the average daily temperature is 26.5˚C. Averaging 4.96 kWh/m² annual solar irradiance and with the range of 4.8 to 6.3kWh/m² irradiance monthly except for December due to the monsoon season ..
Intelligent smart parking with integration of wind energy
No full textIn today’s growth of modern society, modern and “smart” infrastructure is responsible for the most important services inside the campus. Learning environments were so ‘traditional’ back then and it is time for change. What exactly makes a campus “smart”? At the highest level, Smart Campus is about connecting devices, software and people to enable new experience or services and increase operational efficiency [1]. When people, devices and applications on campus share a common technology infrastructure, they can interact with each other to enable experiences and efficiency that were not possible before. It helps students to engage more easily and deeply with campus life. In the other hand, traffic congestion is one of the serious problems especially in the city, the school district and not least in the university area.
Smart monitoring and automatic plant watering for agriculture
No full textNowadays agriculture depends on engineering and technology especially for increasing the production and reducing the manpower. Good irrigation system, drainage system and consideration of the nature conservation are known as the important key in successful farming either in the business field or management as the work become more efficient with the existence of the engineering system and planning. Plants are very beneficial to the living things in many aspects such as giving a hand to balance the environment by cleaning the air naturally and also producing oxygen for man and animals daily usage. These plants are dependent on conventional breeding - watering based on their species and the right amount or exposure of the sun to sustain its life and growth. Besides, plants are one of the living things that give a big impact through the ecosystem by maintaining the climate change and provided food. Water is a main component for the development of plants in agriculture or irrigation. The amount of water received by the plant should be measured according to the requirement of the species, the type of the soil used for the plant and the considering of the weather..
Predicting electrical power generation from photovoltaic panel
No full textAs years pass by, renewable power is generating billions in economic activity with continuous and rapid growth which begins to provide on the guarantee of a clean energy future. Renewable energy, usually referred as “clean energy” is defined as the electrical energy that is being generated from the natural sources or processes that can be replenished. The most common renewable energy includes wind, PV, geothermal, biomass, and hydropower. PV or photovoltaic (PV) cells are made from silicon or other materials that convert sunlight directly into electricity [1], [2]. In Malaysia, distributed PV systems generate electricity evenly and locally for buildings, homes, farms and businesses either through rooftop panels or community projects that power entire neighborhoods. One of the advantages of PV energy is that it has the least negative impact on the environment compared to any other energy sources. It does not produce greenhouse gases and does not pollute the air and water. Moreover, generating own electricity means that there will be less usage from the utility supplier. This will immediately contribute to savings on energy bills. Plus, investment can be made by selling the unused electricity back to the grid, Tenaga Nasional Berhad (TNB) under the Feed in Tarif (FiT) program that has been included in the 10th Malaysia Plan..
