Malé vodní elektrárny ve vodárenském systému

Abstract

The State Energy Concept was approved by the Government of the Czech Republic in May 2015. The concept defines the priorities and desired goals of the Czech Republic in the energy sector, describes the implementation tools of the state's energy policy. The concept sets a perspective for 2040. The need to look for new alternative energy sources and to improve already known renewable energy sources is more urgent. The constantly renewing source of energy is the water cycle in nature. The most common way to use it is to convert the energy of the water flow into electricity. The energy obtained in this way seems to be the most economical, and the production is also ecologically clean. The twentieth century has irreversibly marked the shape of the earth with large bodies of water, the realization of which, as we already know, was not necessary in all cases. When it comes to the environment, we are now returning to 'small areas of water'. Small hydro power plants with guaranteed output and energy production represent in summary a large source of energy, so they can reduce the production of electricity by solid, gaseous and liquid fuels, which are harmful to the environment due to combustion. Most of the hydro power potential that can still be used is concentrated in smaller streams, where there is not much space left for the construction of hydro power plants above 10 MW and there are no suitable conditions for operation. Therefore, the construction of pumped storage hydro power plants is being considered, but the construction of this type of hydro power plant is very expensive. It is therefore possible to use the hydro power potential outside free watercourses. This dissertation deals with the analysis of problems and solutions for the location of small hydro power plants in water systems.
