Full textAbstract:
The goal of this project is to test the possibility to connect the Cogenerational generation of power 138 MW (still in the development stage) to the control room 110 kV in Prostejov production. This merge would product the electrical energy as well as the heat energy for all local area. In this dissertation we will be considering the solution of the steady state (stationary state) of system with the voltage level of 110kV, as well as the influence of the generation of power on this system, there by the suggesting a connection. The Congenerational production indicates higher effectiveness in the transformation of energy during primary production process due to the production of heat energy as well as the electrical energy from the primary power sources. In our country, as well as around the world, commonly used fuels are fossil fuels- coal, crude oil, and gas. As the demand for energy grows, those supplies are slowly running out. Not to mention that those fuels have a negative environmental impact. They are a source of carbon, which causes damage to the atmosphere and leads to global warming. Power plants which do not produce carbon are much safer for the environment, and much more productive. However, the residue of this energy is challenging to dispose of. Nuclear energy has common attributes with renewing the sources of energies that are extremely friendly to our environment. Nuclear power plants also produce enough energy and with the usage of Fourth generation reactors, they will be able to recycle the nuclear fuels. Today, more importance is put on renewing sources which are more gentle for the environment. In the near future, CEZ Company, the largest producer of electric energy is planning to use water energy. Water energy comes from water plants or dams. Other ecological forms of energy include geothermal and solar energies. These two types of energy are not as applicable for our geographical position. Geothermal energy is commonly used on islands where there is an abundance of natural hot springs. The most discussed source of energy is bioenergy. It uses natural wood sources, recycled wood products, and applies bioenergy as a main source for thermal power plants.

Full textAbstract:
Master's Thesis considers the idea of use of renewable energy sources for the generation of electricity. On the basis of reports on climate warming, the European Union took measures, which are mandatory for all Member States and aimed to increase the share of renewable energy in total energy production by 2010. Czech Republic has committed itself to produce 8% of energy from renewable energy sources, the government has created a system of subsidies to renewable energy sources and a system of redemption prices. These measures make energy very expensive. This work deals with the origin of these measures, which are reports on global warming. My work is also comparing predictions on the future status, as well as examining the advantages of investing in renewable energy sources and comparing the prices of subsidized energy with other types of energy.

The theoretical part deals with three “ventilation systems” (VS). The first VS uses a ground/well temperature potential as a energy source for preheating or cooling fresh ventilation air. It was found out that energy savings can be achieved. In the winter, when the air flow volume was considered 150 m3/hr and ground temperature 4 and 8 ° C, the energy savings are in the range of 227-359 kWh. The electricity increase is 6 kWh of energy. In the summer, the energy savings are 17 to 38 kWh, with the electricity increase 8 kWh of energy. The second VS, i.e. system combining ventilation a solar systems, the calculation was carried out in TRNSYS computer program for two objects - a “low-energy house” (LEH) and “two-floor house” (TFH) - and 6 different solar systems modifications. The energy gains at the LEH for the 3 solar modif. are 49, 59 and 46 kWh per year (yearly consumption for heating is 2622 kWh). The energy gains at the TFH for the 3 solar modif. are 86, 134 and 129 kWh (yearly consumption for the heating is 8988 kWh). The third VS is a residential VS with liquid circuit with two compact “heat exchangers” (HE) at the inlet and outlet air. The results shows (compared to VS without heat recovery) that with the air flow volume 150 m3/h the energy savings in the winter are 1761-3148 kWh (16-hour and 24-hour operation mode). The electr. increase is 173 to 262 kWh of energy. In the exp. research the measuring section for the HE measuring was built. Then the conventional materials HE was measured. Is was found out that the selected HE is suitable for installation of the theoretically proposed systems. Its efficiency is in the range 58 - 82 % (with the air flow volume 570-55 m3/h). Measuring section was optimized and measured various hollow fibre HEs. Their efficiency are in the range 38-63 % (with the air flow volume 300-900 m3/h). Results of CO2 measurements shows that CO2 concentration is close to the value of 5000 ppm. It is much higher than max. allowed value 1200
