Smart Substation

Being one of the fastest-growing economies in the world, Bangladesh needs to upgrade its electrical network and aim to reduce dependency on fossil fuel-based energy. For the aging and ever-expanding power network, it is necessary to have a smart substation in order to provide reliable, affordable, and sustainable electrical power. As Bangladesh is looking to integrate Distributed Generation (DG) in the power system, it is high time to think about integrating a smart distribution substation into its power network. In this paper, an investigation of the current power generation structure of Bangladesh was conducted and is described. The major focus was given to the upgradation of the existing substation and distribution setup of Bangladesh by providing suitable architectures, technologies, and communication protocols. Detailed studies of Bangladesh’s prospects to incorporate the new technology and renewable energy into its power network are discussed. ETAP was used to simulate the prospective system to show the feasibility of the prospective smart distribution substation in Bangladesh’s power network.

Electrical power is essential in commercial and social investments like lighting, heating, communications, computers, industrial equipment, transport etc. Therefore hydropower energy is one of the most suitable and efficient source of renewable energy which depends on more than century of experience for this issue. The power capacity and facility are two criteria required for the classification of hydropower plant. The first one consists of five technologies: dammed reservoir, run of river, pumped storage, in stream technology and new technology gravitational vortex. The other one is classified according to power scale is Large, Small, Micro and Pico Hydropower. This paper is focusing on micro hydropower especially gravitational vortex power which increases the sustainability and health of the water as a whole. It presents an overview from both flow and power points of view by discussing the free surface vortex (FSV) and the suitable turbine systems which are used in micro hydropower.

As fossil fuel levels are exhausted, building a more sustainable world is an issue that is coming to the fore as a crucial consideration in the development of new technology. The energy needs of the planet's population are immense, and an environmentally friendly source of energy is desperately needed. Energy harvesting from renewable sources is not a new concept - windmills have been around since the first century - but the desire to harness renewable energy has intensified. Energy harvesting technology is the term given to technology used for collecting unused energy from the surrounding environment and converting it into electrical power. Solar, wind and hydroelectric power are perhaps the best-known of these technologies. However, there are many other forms of energy that are under developed and hold much potential for powering the future. These include vibration, pressure, heat and temperature difference. While large-scale power generation cannot be realised using these sources due to their low levels, devices with low power demands may be able to harness such energy sources, potentially eliminating the need for an external power source. Dr Haruichi Kanaya at Kyushu University is leading a team investigating wireless technology.

Case Based

Partial discharge causes mainly the insulation deterioration. It is the significant symptom and manifestation, and is an important factor of the insulation failure for the electrical power equipment. On the basis of analyzing the physical model of partial discharge, this paper used the online monitoring technology of partial discharge that combines the ultra high frequency (UHF) method and the acoustic emission (AE) method, studied the fault pattern recognition method of partial discharge based on the case-based reasoning algorithm, and established the intelligent fault identification system of partial discharge based on the case-based reasoning. The system can accurately and reliably identify the fault mode type, the specific fault location and severity of partial discharge for the electrical power equipment to make the health evaluation and improve the reliability. Through the application of the new materials and new technology, the load loss of the transformer can drop by 15%, the no-load loss can decline by 50% and the fee of electricity loss can down by 32.5%.

In 2019, JUUL Labs began marketing in the European Union ‘new technology’ pods that incorporated a new wick that it claimed provided ‘more satisfaction’. In this study, we compared design and materials of construction, electrical characteristics, liquid composition and nicotine and carbonyl emissions of new technology JUUL pods to their predecessors. Consistent with manufacturer’s claims, we found that the new pods incorporated a different wicking material. However, we also found that the new pod design resulted in 50% greater nicotine emissions per puff than its predecessor, despite exhibiting unchanged liquid composition, device geometry and heating coil resistance. We found that when connected to the new technology pods, the JUUL power unit delivered a more consistent voltage to the heating coil. This behaviour suggests that the new coil-wick system resulted in better surface contact between the liquid and the temperature-regulated heating coil. Total carbonyl emissions did not differ across pod generations. That nicotine yields can be greatly altered with a simple substitution of wick material underscores the fragility of regulatory approaches that centre on product design rather than product performance specifications.

Conducting Materials

A Thermoelectric Device (TE) is made up of dissimilar conducting materials that take a tem- perature dierence (waste heat) and converts it to electrical power. In addition, depending on the direction of the current ow, a TE can also be used for heating/cooling. The reason why TEs are able to provide heating/cooling and be a source of electrical power is due to the Seebeck and Peltier eect. Due to TEs only having a ZT, figure of merit, value of one a lot of eort is being put into finding materials that could improve the improve the figure of merit. This paper reviews how the TEs are implemented in current applications.

The Impact

AbstractThe use of flow control (FC) technology on civil transport aircraft is seen as a potential means of providing a step change in aerodynamic performance in the 2020 time frame. There has been extensive research into the flow physics associated with FC. This paper focuses on developing an understanding of the costs and design drivers associated with the systems needed and certification. The research method adopted is based on three research strands:1. Study of the historical development of other disruptive technologies for civil transport aircraft,2. Analysis of the impact of legal and commercial requirements, and3. Technological foresight based on technology trends for aircraft currently under development.Fly by wire and composite materials are identified as two historical examples of successful implementation of disruptive new technology. Both took decades to develop, and were initially developed for military markets. The most widely studied technology similar to FC is identified as laminar flow control. Despite more than six decades of research and arguably successful operational demonstration in the 1990s this has not been successfully transitioned to commercial products. Significant future challenges are identified in cost effective provision of the additional systems required for environmental protection and in service monitoring of FC systems particularly where multiple distributed actuators are envisaged. FC generated noise is also seen as a significant challenge. Additional complexity introduced by FC systems must also be balanced by the commercial imperative of dispatch reliability, which may impose more stringent constraints than legal (certification) requirements. It is proposed that a key driver for future successful application of FC is the likely availability of significant electrical power generation on 787 aircraft forwards. This increases the competitiveness of electrically driven FC systems compared with those using engine bleed air. At the current rate of progress it is unlikely FC will make a contribution to the next generation of single-aisle aircraft due to enter service in 2015. In the longer term, there needs to be significant movement across a broad range of systems technologies before the aerodynamic benefits of FC can be exploited.
