Validating technical performance of micro-hydropower plants in Nepal / R.B Thapa in Journal of Agriculture and Forestry University, Volume 3 (2019)
[article]
Title : Validating technical performance of micro-hydropower plants in Nepal Material Type: printed text Authors: R.B Thapa, Author ; Bishnu Raj Upreti, Author ; D. Devkota, Author ; G. R. Pokhrel, Author Publication Date: 2020 Article on page: 25-36 p. Languages : English (eng) Keywords: electrification, indicators, performance, plant factor, efficiency Abstract: Access to electricity is a major factor for socio-economic development of a country. But providing reliable, affordable and
modern energy in rural settlements is a major challenge, especially in the developing countries. Energy service is costeffective through off-grid electrification due to scattered settlements, whereas micro-hydropower plant (MHP) is an effective
complement to grid-based power due to its enormous potential. However, these off-grid MHPs are sometimes debated to be
performing below standard which motivated the author to analyze and validate the technical performance of existing MHPs
comparing with national standards. This paper presents the performance analyses of 84 MHPs supported by Alternative
Energy Promotion Centre (AEPC) in Nepal. The results showed that water-to-wire efficiency mean is 59.2%, performing
above designed value. Similarly, electro-mechanical (E/M) efficiency performed above national standard. Water-to-wire,
E/M, and turbine efficiencies are positively influenced by increase in plant size, but penstock efficiency remains same,
irrespective of plant size. Majority of plants are performing reliably, the plants performing un-reliably is mainly due to
insufficient flow. Mean value of plant factor is 27% which is influenced by plant size and energy consumption per household.
Lower value of plant factor refers that there is high potentiality to improve energy based economic activities.Link for e-copy: https://afu.edu.np/sites/default/files/2._Validating_technical_performance_of_mi [...]
