Usina de Itaipu! Funcionamento elétrico!

How does the Itaipu hydroelectric plant in Paraná work? Mundo da Elétrica interviewed an engineer from the plant, Henrique Gomes. He knows the history and answered several technical questions about the dam, the generators, the plant's capacity, height, cost, where it supplies power, etc... The visit to the plant is a must-see for anyone who has contact with the electrical sector and visits the city of Foz do Iguaçu. Itaipu was built a long time ago and is still an important landmark in the generation of energy in the country! This video is a summary with several photos and images of Itaipu Binacional. Among the objectives of this video, we highlight: Present important information about the Itaipu hydroelectric plant. We address the following items throughout this video: The Itaipu hydroelectric plant has an installed capacity to produce 14GW of electricity, being the second largest plant in terms of energy generation. The first is Three Gorges in China. The Itaipu power plant, owned by Brazilians and Paraguayans, is currently responsible for the energy of approximately 36 million people. Approximately 17% of the Brazilian population and 75% of the Paraguayan population. Brazil's energy matrix is ​​predominantly hydroelectric, but it also has thermal, wind, solar and nuclear power plants. Itaipu works directly with the ONS to define how much energy should be generated at any given time. The energy is stored in the river's reservoir, which is dammed, so it is possible to generate more or less energy depending on the number of turbines that are turned on. In total, Itaipu has 20 turbines. Once every 3 years, each turbine is shut down for maintenance that can last up to 12 days. Everything must be previously agreed with the ONS. - There are 8 transmission lines carrying energy from Itaipu, 4 going to Brazil and 4 to Paraguay. Each line has 3 phases with 4 cables in each, totaling a voltage of 750KV. The frequency of the energy generated is controlled in the forced conduit by the amount of water that passes through the turbine. This control is done through a PID system. The generators generate the three phases at the same time. They rotate at a speed of 92.3 RPM for a frequency of 60Hz and 90.9 RPM for a frequency of 50Hz. Itaipu is not a reversible hydroelectric plant. This type of plant reuses the water that passed through the forced conduit by pumping it back up so that this water can be reused. The plant's grounding system is huge, consisting of many kilometers of meshes, cables and grounding bars, including in the transmission towers that leave the plant. The lightning protection system is also very complex and large. Due to the size of the generator parts and other parts of the plant, the complexity of replacing these parts is immense; some parts take more than 40 days to reach the plant from their place of manufacture. Parts highlighted in this video (edit notes): 00:45 - Several technicians and engineers work at the Itaipu hydroelectric plant. It is interesting to know and understand what each professional does in their field of training. 07:10 - When we talk about energy generation, we always talk about consumption, that is, how much electricity we consume, and a major concern is how much we pay for the electricity we consume. 13:08 - The Itaipu plant is part of the SEP, the electrical power system in the electricity generation area. 18:34 - A power plant's generator must rotate at a constant speed so that there is no variation in the electrical frequency, and a formula is used that takes into account the number of poles and the angular phase shift between them to define this speed. 23:33 - The Itaipu power plant is part of the SIN, the national interconnected system that interconnects the electrical system of more than 97% of Brazilian areas.
