Large hydropower project (LHP) is now the most important renewable and low-carbon source for electricity generation, carbon footprint calculation is crucial for it. We established an embodied carbon budget accounting system for LHP to calculate its actual carbon footprint. In additional to traditional carbon emission from plant construction, the accounting system included two new items in the c...

BACKGROUND Hydropower plants provide more than 78 % of Brazil's electricity generation, but the country's reservoirs are potential new habitats for main vectors of malaria. In a case study in the surroundings of the Manso hydropower plant in Mato Grosso state, Central Brazil, habitat suitability of Anopheles darlingi was studied. Habitat profile was characterized by collecting environmental dat...

Hydropower is the largest renewable source of electricity generation, carbon emissions which have attracted a lot attention. However, system boundaries existing studies are either incomplete or inaccurate. Therefore, this study provides systems accounting framework for evaluating both direct and indirect from hydropower plant. It based on hybrid method as combination process analysis input-outp...

Stand-alone hydropower plant is a major energy source in grid isolated zone because they do not require dams to be built. In stand-alone Voltage and frequency, instability caused by the load variation. This can cause alternator spin very quickly or slowly, causing induced voltage output frequency rise fall. Furthermore, if rate of growth too high low, appliances connected generator undergo huge...

1 Recent droughts and heatwaves showed the vulnerability of the electricity sector to surface water 2 constraints with reduced potentials for thermoelectric power and hydropower generation in different 3 regions. Here we use a global hydrological-electricity modelling framework to quantify the impacts of 4 recent drought and warm years on hydropower and thermoelectric power usable capacity worl...

[1] This paper presents a novel approach for modeling high-elevation hydropower systems. Conservation of energy and energy flows (rather than water volume or mass flows) is used as the basis for modeling more than 135 high-elevation high-head hydropower sites throughout California. The unusual energy basis for reservoir modeling allows for development of hydropower operations models for a large...

This paper aims to present the benefits achieved in the ergonomics process management with the use of the TPM methodology (Total Productive Maintenance) in Tucuruí Hydropower Plant. The methodology is aligned with the corporate guidelines, moreover with the Strategic Planning of the company, it is represented in the TPM Pillars including the Health Pillar in which is inserted the ergonomics pro...

We describe some features of a three-dimensional numerical simulator currently under development for studying water physico-chemical properties during the flooding of hydroelectric plants reservoirs. The work is sponsored by the Brazilian Electric Energy National Agency (ANEEL) and conducted with Furnas Centrais Elétricas S. A., the leading Brazilian power utility company. An overview of the si...
