a. Describe 5 major advantages associated with High Voltage Direct Current (HVDC) distribution systems when considered alongside alternative solutions. [5 marks] i) HVDC have lower losses when compared to the equivalent AC cable distribution. The DC power transmission lines run at losses of approximately 0.3-0.4% per 100km. Converter stations also need to be considered which have losses of around 0.6%. Overall HVDC transmission losses are nearly always lower than AC transmission. ii) HVDC…

The word “photovoltaic” combines two terms – “photo” means light and “voltaic” means voltage. A photovoltaic system in this discussion uses photovoltaic cells to directly convert sunlight into electricity. A photovoltaic (PV), or solar electric system, is made up of several photovoltaic solar cells. An individual PV cell is usually small, typically producing about 1 or 2 watts of power. To boost the power output of PV cells, they are connected together to form larger units called modules.…

4.4.2 Environment: Committed to Environmental Responsibility For Total, being one of the industry leader means that it must also be able to protect the environment. It is therefore important to ensure that everyone has energy and this in an environment that is respected. Due to the general interest, Total wants to fight climate change. Because of its activities such as the use of petroleum products and gas as well as its commercialisation, the responsibility of Total will implement carbon…

Because of the static configuration is a stable one, in the absence of streaming, the density of the upper fluid be lighter than the density of the lower one. The basic unperturbed flows have uniform velocities and . The two fluids are dielectrics and having the uniform dielectric constants and . The two fluids are influenced by an oblique electric field at the interface between the two media, according to: (2.1) where…

Solar Updraft Towers Solar updraft towers were designed as an alternative to other current energy sources that are nonrenewable by using kinetic energy to transfer heat. The technology in a solar updraft tower is that it incorporates a large greenhouse-type structure, referred to as a collector, which generates heat from the sun and transfers the heat by convection out of a tall chimney tower that is at the center of the structure. As hot air rises and evacuates from the top of the tower, a…

Though sloping roofs are commonly used all over America, flat roofs are steadily gaining a lot of popularity. This is mainly because they have a host of benefits to offer as far as homeowners are concerned. Now, there might be some of you who do not have a clear idea as to what flat roofing actually is. Well, they are not entirely flat but have a slight amount of slope that is usually of about 10 degrees to facilitate draining of water and snow. The concept of flat roofs was introduced centuries…
