Based on the analysis of current developments in small hydropower plants, the structural scheme and installation scheme of a dam without hydropower were developed. According to the developed scheme, a small hydroelectric power plant was installed and prepared for testing. During the study, an analysis of 3 magnitudes (V), voltage frequency (Hz) and sinusoidal coefficient (%) that determine the quality indicators of electricity was presented. The obtained results are compared with the value limits given in the international standard normative document.
This paper provides an opportunity to increase the efficiency of use in low-pressure watercourse systems by determining the dimensions and design of the micro-hydroelectric power plant operating on low-pressure watercourses. It was found that the size of a micro-hydro water turbine depends on the flow rate of the water, the volume of water hitting the blade at a fixed time, and the depth of the water surface. As a result, a technological scheme of a micro-hydroelectric power plant operating on low-pressure water streams was developed.
Electric energy production in small-scale hydropower stations is attractive from both an ecological and an economical point of view. Technological innovations and measures to lessen environmental impacts make small-scale hydropower stations inexpensive and justified energy sources that provide renewable energy on an independent basis and help not only to protect the environment but also to weaken human dependence on fossil fuels. This study is devoted to finding solutions based on renewable energy technologies and innovations in Uzbekistan. This article is devoted to the development of a water wheel experimental model for the micro-hydroelectric power station. Experimental studies were carried out on the basis of this model and obtained results were used in the preliminary calculations. The results from the calculations showed that the installation can generate 7-11 kWh of electricity per hour, about 168-264 kWh of electricity per day and 61 to 96 MWh of electricity per year.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
