This book has grown from Intermediate Technology’s field experiences with micro-hydro installations and covers operation and maintenance, commissioning, electrical power, induction generators, electronic controllers, management, and energy surveys.
Community Based Micro-Hydro Village Electrification Scheme Technology and Approach
Booklet on community based micro hydro village electrification scheme technology to explain how science is used in technology development.
Is a Community Based Micro-hydro Electrification Scheme Suitable for Your Village?
This document helps a lay person to understand and gain an idea as to whether their village has a potential to meet its own electricity needs through a community based micro-hydro village electrification scheme.
Development of a rainfall forecasting model for Sri Lanka using artificial feed-forward neural network
A rainfall forecasting model for Sri Lanka is constructed using artiﬁcial feed-forward back-propagation neural network. The data obtained from meteorological station in Colombo is used. The rainfall data with the humidity and atmospheric pressure measurements taken at the ground level are used to train the network. The preliminary results indicate that the model is successful in predicting rainy days one day ahead in Colombo area with the accuracy of 67%.
Operation & Maintenance of Community Based Micro-Hydro Village Electrification Schemes
For the smooth running of a micro-hydro village electrification scheme, proper operation and attending to at least preventive maintenance is vital. Small instances of neglect can lead to large problems for the whole scheme. Even a small repair may have to be attended to without delay so as to ensure the whole system is running smoothly.
Advance Control System for Small Hydro Power Project
Small hydro power projects play a significant role in renewable energy sector in Sri Lanka. Among different categories, community based and estate based hydro projects use electric load control technology since it can be locally manufactured, easily adopted in to old existing hydro plants and the low cost. However, power electronic control technology reduces the lifetime of the controller itself and the other components of the system; therefore it is not an efficient and viable technology in the present context. Most of the estate based hydro projects have been abandoned due to…
