The solar-hydroelectric (SHE) energy system is a renewable hybrid consisting of solar and hydroelectric energy. An optimization algorithm has been designed to work out the installed power size SHE system, which planned be integrated into existing systems. This provides optimum with benefit/cost approach. value hydro cost also generation taken from actual values since it's an facility, electrici...

A study was carried out in the area of influence of the Porto Primavera Hydroelectric Power Station, in western São Paulo State, to investigate ecological and epidemiological aspects of malaria in the area and monitor the profile of the anopheline populations following the environmental changes brought about by the construction of the lake. Mosquitoes captured were analyzed by standardized indi...

BACKGROUND Refining the spatial and temporal data on malaria transmissions at a defined ecological setting has practical implications for targeted malaria control and enhancing efficient allocation of resources. Spatial and temporal distribution of P. falciparium and P. vivax were explored around the Gilgel Gibe Hydroelectric Dam (GGHD) in southwest Ethiopia. METHODS A review of confirmed mal...

Electricity production is a challenging issue when it comes to mitigating greenhouse gases (GHG) emissions without risking development goals. Non-renewable energy sources, as fossil fuel burning, account for most of the global energy production (68% in 2007) and are responsible for most of the anthropogenic GHG emissions to the atmosphere (40%, International Panel on Climate Change IPCC, 2007)....

The hydroelectric power plants use technical instructions of maintenance and operation to instruct maintainers and operators about the maintenance and operation procedures to be executed in their generating units. These instructions consist of well defined scripts with 2d flat drawings and of activities in textual format. This paper presents an authoring tool that allows the construction of the...

This paper presents an overview of the effects of electric power generation and transmission on indigenous communities in Brazil. According to data from FUNAI (the Brazilian government's Board of Indian Affairs), there are 156 cases of direct impact, present or future, of the electric power sector on Indian settlements geographically distributed throughout Brazil, 65% of which are located in th...

We consider the optimal scheduling of hydropower plants in a hydrothermal interconnected system. This problem, of outmost importance for large-scale power systems with a high proportion of hydraulic generation, requires a detailed description of the so-called hydro unit production function. In our model, we relate the amount of generated hydropower to nonlinear tailrace levels; we also take int...

Abstract The aim of the work is to develop theoretical and methodological foundations for predicting likelihood fires in premises hydroelectric power plants, as well compiling algorithms monitoring fire safety system, “Serviceability control” technological process “Fire” process. In course work, studies methods assessing generating enterprises “man -machine -environment” system ways occurrence ...

Slapy hydroelectric plant (HPP) is a typical mid-head HPP hosting three 50 MW Kaplan turbines on the Vltava river, 50 km south of Prague, Czech Republic. The gross head is 47 ÷ 53 m in normal operation regime. Pressure-time (PT) flow measurement method was specified for the acceptance tests of the upgraded Unit #3 in autumn 2011 and OSC had the contract for those tests. ASL AQFlow proposed to b...
