Abstract:

Development of micro-hydropower schemes in rural areas of developing countries is largely depended on simple and affordable systems. The contra-rotating pipe turbine, produced by GreenEnergy is a one-piece and easily operated turbine, designed as the Rolls-Royce of turbines with good operational qualities. Suitable for low head sites, this turbine is easily installed in existing plants, for minimum passage flows or independent schemes supplying electricity to rural areas.The contra-rotating prototype will now be donated to a site in a developing country and the river Una, near Marangu Hotel in

Abstract:

Research on the electrical characteristics of hydroelectric power systems has to the author’s knowledge, not received much attention. However, renewed interest in hydropower microgeneration has created a need to understand the underlying properties. This thesis presents a pioneering empirical investigation into the electrical characteristics of micro- hydro power generators (MHPGs). An ohmic characteristic behaviour in MHPGs with constant source impedance, even with varying water flow is demonstrated for the first time. Experimental results showed variable flow correlation between the MHPGs vo

This paper presents renewable energy, power electronics, and distributed generators. The focus is on wind farm generator, photovoltaic cell, and battery bank system. Power Conditioning system improves the performance of a power system. Apart from the benefits of converting between DC/AC, there is adequate control of real power and additional control of economic reactive power. This is possible because of multiple sources in the system. This project throws light on the basic principle of power system conditioning, its operation and control, and the economic studies.

Harvesting energy from ultra-low-power vibration energy sources typically employs a rectifier circuit as the first power conditioning stage. The Schottky diode has a 0.15 V - 0.2 V threshold voltage and can not extract energy efficiently at low voltage. Other technologies such as MOSFET bridge or active diode are designed to minimize the voltage drop to reduce the conduction loss. However, these designs require either additional power supplies to operate comparators or have a larger threshold turn-on voltage than Schottky. Therefore, most rectifiers have an unresponsive or significant low-effi

Cooling, Heating, and Power (CHP) is an emerging category of energy systems consisting of power generation equipment coupled with thermally activated components. The application of CHP systems to residential and small commercial buildings is known as micro-CHP (m-CHP). This instructional module has been developed to introduce engineering students to m-CHP. In the typical engineering curriculum, a number of courses could contain topics related to m-CHP. Thermodynamics, heat transfer, HVAC, heat and power, thermal systems design, and alternate energy systems courses are appropriate m-CHP topics.

Abstract:

This thesis describes the development of a simplified propeller turbine unit to produce power in a low head micro hydroelectric power installation. To be appropriate for remote areas and developing countries, a micro hydro system needs to be simple in design. There are good turbine designs for medium to high heads but traditional designs for heads under about 10m, ie, the crossflow turbine and waterwheel, are slow running, requiring substantial speed increase to drive an AC generator. Propeller turbines have a higher running speed but are normally too complicated for micro hydro installations

Abstract:

碩士<br>國立交通大學<br>電控工程研究所<br>102<br>Energy harvesting has a very important position in the academy field for over ten years. Earlier devices are fabricated on rigid substrates. Nowadays, this field focuses on fabricating micro-power generators on flexible substrates. In this thesis, we use PDMS to fabricate device and bond PDMS to form an enclosed cavity. Then, we inject ferro-fluid and silicon oil in the cavity. When the device is pressed, the two fluids will flow back and forth. Because of the permeability difference between the two fluids, the magnetic flux will change with time in the dev

碩士<br>國立臺灣科技大學<br>電機工程系<br>99<br>This thesis develops a micro-photovoltaic(PV) solar power system. The system contains a DC-DC power converter and a DC-AC power converter. DC-DC power converter uses a new high step-up ratio isolated DC-DC power converters to boost the output high voltage from solar cells. DC-AC power converter is a single-phase full-bridge inverter which can be either operated in stand-alone fashion with voltage control or connected with power grid using current control. In this thesis, a new feed-forward compensation with maximum power point tracking of PV system, together wi

Abstract:

Energy harvesters collect and convert energy available in the environment into useful electrical power to satisfy the power requirements of autonomous systems. Vibration energy is a prevalent source of waste energy in industrial and built environments. Vibration-based energy harvesters, or vibration-based micro power generators (VBMPGs), utilize a transducer, a mechanical oscillator in this application, to capture kinetic energy from environmental vibrations and to convert it into electrical energy using electromagnetic, electrostatic, or piezoelectric transduction mechanisms. A key design fea

Abstract:

Micro power management (muPM), a standard-compliant MAC level solution to save power for active 802.11 interfaces is developed. muPM enables an 802.11 interface to enter unreachable power-saving modes even between MAC frames, without noticeable impact on the traffic flow. To control data loss, muPM leverages the retransmission mechanism in 802.11 and controls frame delay to adapt to demanded network throughput with minimal cooperation from the access point. Extensive simulation has been conducted to systematically investigate an effective and efficient implementation of muPM. A prototype muPM
