VEGA - Towards a new era with super speed

Crude oil reserves are rapidly diminishing. Therefore the prices of the petroleum are rising. Further the burning of petroleum oil causes deadly effects towards the environment with millions of vehicles in the world. That number is enough to have a clear image about the amount of the petroleum burnt per second in the world. These clues give us the evidence to switch our energy sources currently used in vehicles to a clean energy source. Timely necessity of an Electrical vehicle……… Electricity can be generated with less or no effect to the environment. There are plenty of non-conventional renewable methods to generate the electricity. Therefore it is foreseen that there will be an optimistic future for electricity generation which can be...

Design and Build a Real Life Power System Model

Introduction It is important for an Electrical Engineering undergraduate to know about power systems in theoretical as well as in a practical approach. Thus, a power system simulator is ideal to understand practically the theories learnt in class. Commercially available models though are in existent, the endeavor was taken to design and build a power system simulator, as a final year project. The simulator is a scaled down model of the actual power system prevailing in the Sri Lankan context. Though it is a scaled down model, all electrical components such as generators, relays, circuit breaker panels are all actual industry used components. As a continuing project many aspects are being developed piece by piece under the guidance of the...

Development of a prototype of vehicle active suspension system

Introduction The aim of the project is to develop an active suspension system for vehicles. In this project, the main objective is to suppress the vibrations caused due to the imperfections of the road surface and give a better stability to the sprung mass. In order to achieve this goal, the suspension system changes its characteristics and suppress the vibrations according to the vibration level of the road and applied disturbances. Project scope The proposed method consist of a controller, linear motor driver, linear motor acting as an actuator and feedback sensors are used to complete the control system. The controller will accumulate suppressed vibration performance details of the system and takes position feedback of the motor using...

E-waste - A national issue to be considered...

Electronic waste (e –waste) is one of the major environmental issues which are currently faced by the developing countries as well as the developed countries all around the world. With the rapid technological development, many innovative products arrive to the market. The demand for those innovative products is growing day by day and those innovative products replace the existing ones. Thus, that will create a hazardous situation regarding the disposal. In our country – Sri Lanka too, the current consumption of the new technological equipment is increasing in a considerable rate with respect to the past and the disposal of waste will be a huge issue, in the near future. So, it’s very much convenient to be aware of e – waste, its impact and...
