Evaluation of the possibilities of using water-damming devices on the Tyśmienica River to build small hydropower plants

Abstract

Hydropower plants in Poland currently use only 19% of the river's energy potential. Development of hydropower is limited by environmental regulations as well as by economic grounds. From the environmental point of view, it is desirable to build small hydropower plants integrated into the local landscape. This paper presents results of the research aimed at estimating the amount of energy that could be produced in the case of small hydroelectric power plants on weirs existing on the Tyśmienica River. There is also a legal framework that should be adapted at hydropower development. It was calculated that the technical capacity of the small hydropower plants that could be built on 4 existing weirs, is 0.131 MW. These power plants could produce 786 MWh of electricity per year. The economic efficiency of this production is currently difficult to assess, because a new support system for renewable energy sources is currently being implemented, which will be a decisive factor for entrepreneurs. It should be borne in mind that potential investments will be made in protected areas within the Natura 2000 network, which may limit their constructing or impose the obligation to assess their impact on selected environmental elements. Location within the protective area does not eliminate such investments, especially when solutions with the least possible environmental impact are used.

Effect of Diagonal Formation of Plate Perforations on the Tyrol Weir Discharge Coefficient Value

“…Therefore, appropriate efforts are needed in water management for irrigation and other activities [1]. In some ceses there is a decrease in the groundwater level, in future it is necessary to make various efforts in the use of irrigation and other activities [2]. For water flows in rivers containing small and large size sediments [3], there needs to be a solution so that they can be tapped into irrigation channels by making tyrol dams.…”

Analysis of the overvoltage cooperative control strategy for the small hydropower distribution network

“…In ref. [8,9], measures such as changing line parameters, adjusting transformer ratio, changing generator terminal voltage, generator phase-in operation, and accessing parallel reactive power compensation device were pointed out. The three stages of voltage regulation of the generator's phase-in operation, the installation of shunt reactors and the modification of transformer taps were analyzed, and a comparative analysis of the effects of voltage regulation was carried out in ref.…”

“…Besides current climate change and extreme events, there needs to be an appropriate strategy for the development of irrigation and water use control [ŁABĘDZKI 2009]. The analysis revealed a shift in the time of the decade with minimum groundwater content, for example in an area from three decades for layers of 0-10 cm to seven in terms of layers with a thickness of 0-40 cm so that it needed en-gineering to utilize river water for irrigation purposes [KOWALCZYK-JUŚKO et al 2017]. Moreover, the river drains sediment which grain size of sediment particles tends to decrease along the water flow direction [BĄK, DĄBKOWSKI 2013].…”
