Small hydro power installations have the potential to provide a renewable supply of energy to people in remote, hilly communities, far from the national grid. This book is based on the authors' considerable experience of installing hydroelectric schemes that produce up to kW for powering small communities. It describes not. Waterpower is the largest source of renewable energy in the world today, and microhydro is a mature, proven technology that can provide clean, inexpensive, renewable energy with little or no impact on the environment.
Serious Microhydro brings you dozens of firsthand stories of energy independence covering a complete range of. Project to develop a simple method and the necessary controls that would allow the use of standard three phase induction motors as generators for low cost micro-hydro systems.
Two different types of systems were developed, the first of which was for charging batteries on simple direct current systems and the. But despite lively interest in renewables generally, there is an information vacuum about the smallest version of the technology dubbed "the simplest, most reliable and least expensive way to generate power off grid. The role of small hydropower is becoming increasingly important on a global level.
Increasing energy demand and environmental awareness has further triggered research and development into sustainable low-cost technologies. In developing countries, particularly in rural areas, the possibility of local power generation could considerably improve living conditions. With this in. Providing essential theory and useful practical techniques for implementing hydroelectric projects, this book outlines the resources, power generation technologies, applications, and strengths and weaknesses for hydroelectric technologies.
Emphasizing the links between energy and the environment, it serves as a useful background resource and facilitates decision-making regarding which renewable energy technology. The book describes in. Today's wind energy industry is at a crossroads. Global economic instability has threatened or eliminated many financial incentives that have been important to the development of specific markets. Now more than ever, this essential element of the world energy mosaic will require innovative research and strategic collaborations to bolster the.
It describes the theoretical basis of the work, the main research activities, and the practical outcomes of the implemented. Field Guide to Appropriate Technology is an all-in-one "hands-on guide" for nontechnical and technical people working in less developed communities.
Currently, development of micro- electrical energy. Small hydro-power plants and hydro turbines considered expensive and micro-hydro power plants have acquired increasing unreachable because it needs the specific spare attention due to their ecological irreproachability parts, requiring infrastructure development, spare and acceptable prices for generating available parts are difficult to find in the market so the prices electricity without producing harmful unexpected become costly, and maintenance requires pollution and greenhouse gases [6].
The specialized knowledge. On the other hand, many hydroelectric power plant has several advantages, people who live in mountain areas not enjoyed that is, cost of hydroelectric power is relatively low; electricity, although they are living near the rivers.
The river flow floating portable micro-hydro is Figure 1. The buoys one of the solutions. There is one certainty when designing and installing self-help micro-hydro In figure 1 show at the front of the buoy is systems in remote areas-this is that the problems connected the other pipe using the elbow to form a will be many and varied [4].
Micro-hydro is power degree angle. The degree vertical tube is plants which are converted rivers flow energy to useful to withstand collisions from other hard twist energy by the turbine and then twist energy objects floating on the surface of the river. The non- B. Buckets dam hydro technology has no need for constructing All Buckets are used to capture the flow of river a dam, which could have drawbacks regarding the water and convert it into twist energy. Buckets are ecology in some areas [5].
The ability to float make designed like the Pelton; when the water comes to micro-hydro can adjust the river's surface elevation. Micro-hydro designed to portable size so it easy to The Pelton turbine consists of specially shaped move around. With these capabilities will make buckets [2].
Water in the form of a jet impinges on micro-hydro easily during the installation process, the central splitter and divides into two equal the installation requires small human resources, streams before leaving the bucket in a direction river structure changes not needed, and easy to opposite to that of the incoming jet [2]. This Bucket maintenance. Frame made from the iron rod and bucket walls This document is a template.
An electronic copy made from aluminum plate material. The diameter can bedownloaded from the conference website. For questions onpaper guidelines, please contact the conference publicationscommittee as indicated on the conference website.
Information about final paper submission is available from the conference website. Turbine Buckets hydro. First, every component produced one by one. Next, unified to become a complete unit. This device consists of several components, viz: Figure 2 shows the bucket on a turbine that is used to convert the rivers flow energy into twist A. Buoys energy. The diameter of the turbine is cm.
The Buoys are used to make the micro-hydro have the micro-hydro consists four turbines so it can increase ability to float. Buoys made from PVC pipe the thrust of water to the turbine. Every turbine is material. The diameter of PVC pipe is 10 cm, connected each other. PVC pipe arranged in parallel as much as two upwards and eight to sides so it can float for the kg load.
Turbine Position Figure 5. Body Frame Figure 3 shows on a micro-hydro have four turbines, and turbine position is not parallel on the From Figure 5 shows that the frame was made front with the back of micro-hydro. The turbine in simple. We are using welding to create the frame.
This velocity. It will increase turbine capability for thrust of water. This floating portable micro-hydro has four turbines used to rotate the rotor of a generator. Aligning the rotation of the front turbine and rear turbine should use the same poley size.
Figure 6. Frame Position Figure 6 shows the connection between the frame Figure 4. The frame for casing. Generator Low RPM turbine was using the iron pipe. The essential components of hydro-power are D. Body Frame turbines and generators, the function of turbines is The body frame was using to buffered all converted the potential energy of water to the twist components such as generators, turbines, shafts, and energy, and the generator converted it into electrical casing of the body.
The axis generator or the so-called rotor will rotate, the rotation will bypass the magnetic force line from the stator to produce electric motion induction. This floating portable micro-hydro Figure 8 shows the casing of a floating portable design was using the low-RPM generator. The components that on outside of turbine body are only turbines and buoys because these parts are directly affected by river flow. Expected Flotation The expected buoyancy of the turbine to work as well is about 20 cm from the lower ends of the turbine.
Figure 7. Generator Low RPM The floating portable micro-hydro was utilizing a generator with permanent magnet generator. The specifications of the generator that is, small size, easy installation, rotor using a patented alternator, Figure 9.
