As more and more reservoirs are built, concentrated water releasing in the dry season will bring about additional flow compensation and the joint operation of cascade hydro plants is quite important. This paper discusses the water level decline strategy of four cascade hydro plants in the Jinsha River and analyses the relationship between guaranteed output and total power generation. ...

On 19 September 1960, the Indus Water Treaty (IWT) was signed between India and Pakistan, presumably resolving the conflict of Indus water sharing. Nevertheless, over the years the conflict has re-appeared, dragging both the riparian states into confrontation. This paper explores the reasons that lead to conflict despite the Indus water sharing having already been resolved by the IWT. Analysis ...

The flanks of plastic parts are usually provided with holes or flutes. Under such conditions, side-direction forming cores must be used to form plastc parts. However, such cores must be developed into active parts so that they can be pulled out prior to the stripping of plastic parts. The mechanism for pulling out and restoring such active cores is called  ...

Current practices in the nuclear industry to model the transient behaviour of nuclear reactors are based on the use of different solvers for resolving the different physical fields, and to some extent the different scales. The overall time–dependence is computed by a coarse–mesh neutronic solver coupled to a coarse–mesh thermal–hydraulic solver. The meso–scale information in the thermal–hydraulic ...

I imagined some new technique and I want to introduce it. This is only an ideology and not experimented yet. If anybody wants to experiment this i have no objection. According to me any technology that helps the mankind must be universal. I don’t want like anybody’s monopoly on this technology. I wish this technology should be experimented and make this available to generate power, ...

Better access to improved infrastructure services is an important engine for economic growth. The poor state of infrastructure is a key bottleneck to growth in African countries, and Cameroon is no exception. Between 2000 and 2005, improvements in information and communication technologies boosted Cameroon's growth performance by 1.26 percentage points per capita, while deficient power ...

The Nam Theun 2 Hydroelectricity Power Project (NT2), located in the Khammouane Province of central Lao's People Democratic Republic (Lao PDR), aims to produce electricity with a generating capacity of 1,070 MW. Most of the electricity generated (995 MW) will be sold to the Electricity Generating Authority of Thailand (EGAT) and the remaining (75 MW) sold to Electricite du Laos (EDL). The primary ...

This work presents the development of a LabVIEW web–based post–processor for the RELAP5 output. A RELAP5 model was developed for the thermal–hydraulics experimental facility, called Natural Circulation Circuit. A Visual Basic for application program (Xtrip) was developed to transform binary data file from RELAP5 in an ASCII file. This new output file can be displayed in user–friendly Graphical ...

This paper presents a comparative evaluation of two multiple-loops duty-cycle-based control schemes applied to a three-phase three-switch three-level boost-type rectifier. The control laws are both elaborated on the basis of a state-space averaged model of the converter, expressed in the synchronous rotating frame. On the one hand, a control scheme that uses linear regulators is designed by using ...

This project will support the Task Force in its effort to create an enabling environment for renewable and distributed generation technologies in Partner countries. The project will focus on all Partner countries in order to identify specific barriers impeding hydropower investment in each country. Partner countries have identified more than $200 billion in hydropower investment necessary for ...

In this paper, an experimental technique is introduced to investigate the structural response under impact loads, which consists of the waveform measuring technique in the time domain by using the WAVEVIEW software, and steady-state measurements by using the Polytec Laser Scanning Vibrometer (PLSV) in the frequency domain. The waveform measuring technique is introduced to obtain the waveform at ...

A three-dimensional neutronic code POWEX-K has been developed, and it has been coupled with the subchannel thermal-hydraulic core analysis code MI based on the momentum integral model. This forms the integrated neutronic/thermal hydraulics code system POWEX-K/MI for the accident analysis of the training and research reactor at the Budapest University of Technology and Economics (BME Reactor). An ...

There is a lot of current debate about whether the State of WA should require utilities to make greater investments in energy efficiency. This has caused some waves within the business community which has legitimate concerns about energy prices and is usually in opposition to government mandates and. Although not proven, the common belief amongst businesses is that laws requiring investments in ...

Fuzzy sets and interval analysis tools to make computations and solve optimisation problems are presented. Fuzzy and interval extensions of Decision Theory criteria for decision-making under parametric uncertainty of prior information (probabilities, payoffs) are developed. An interval probability approach to the mean-value criterion is proposed.Keywords: fuzzy sets, interval analysis, ...

This paper deals with the power quality improvement of AC mains in Direct Torque-Controlled (DTC) permanent magnet synchronous motor (PMSM) drive using active wave shaping techniques. For this purpose, different topologies for active wave shaping of AC mains current in DTC-based PMSM drive such as single- and two-switch boost power factor correction (PFC) AC–DC converter, asymmetrical two-switch ...

In this paper, an analytical model for a multi-plate thermoacoustic system is developed. The governing momentum and energy equations are simplified to quasi-one-dimensional forms using reasonable approximations. The expressions for the fluctuating velocity (u1), fluctuating temperature (T1), Nusselt number (Nu), fluid friction irreversibility ...
