Lisää tagi | Yhteenveto: | The present degree work allowed the Agoyán hydroelectric power plant to study the current protection of generation unit #1 to determine the system's correct functioning for the future modernization of the current protection system. The thesis's main objective was to evaluate the settings of generator #1 of the plant's protection system. The project began with collecting information on the current electrical model system of the power plant, where data was collected on generators, transformers, transmission lines, loads, and current settings of the protection system of generator no. 1. through a field survey of information in the Hydro-Agoyán Power Plant, allowing to establish a current electrical model using the DigSILENT computer program to develop the power flow short-circuit study. The power flow study evaluated the operability of the electrical power system's elements under two demand scenarios: maximum demand and minimum demand. This study determined the effects in the area of influence when connected to the Ecuadorian national interconnected system, obtaining results that allow the correct operation of the power plant's generation to be verified, such as busbars voltages, máximum dispatch power, and load ability of the main elements of the power plant, complying with the parameters established by the Ecuadorian Electrical Sector Regulator. The short-circuit study made it possible to determine the maximum and minimum short-circuit currents by simulating single-phase ground and three-phase faults at the 13.8 kV and 138 kV busbars; this was necessary to obtain values that were used to evaluate and adjust the protection functions of generator #1. Taking into account the needs of the Agoyán power plant for the protection of generator #1 and after studying in detail the main characteristics of the protection system on the generator, applying standards, bibliography on the subject and with the results obtained from the power flow and short-circuit study, the current protection system of the power plant was evaluated. Finally, the results obtained from the valuation of the protection system of generator #1 of the power plant were presented, and the conclusions and recommendations have arisen after the development of the present thesis work |
