Assessment of Faults in the Performance of Hydropower Plants within Power Systems

Energy is crucial for a country's development, with renewable and non-renewable sources being the most environmentally friendly. One advantage of a hydropower plant is that it produces clean, renewable energy, while a disadvantage is that it can have negative impacts on local ecosystems and wildlife. This study focusses on monitoring and assessing faults such as changes in reference power and three-phase short circuits in hydropower plant. The analysis involves examining these faults in various parameters, including voltage and current of the generator, power and reactive power, generator output power, deviation in generator speed from its rated speed, generator rotational speed, torque, and d and q axis voltage of the generator. The simulations were conducted using MATLAB/Simulink. The results of the simulations demonstrate the effects of these faults on the parameters, providing valuable insights for monitoring the hydropower plant under such conditions. Overall, the generator's performance in both scenarios demonstrates its reliability and effectiveness in maintaining power supply during unexpected events. The successful outcomes in both cases highlight the importance of having a robust and well-functioning generator system in place for ensuring continuous power supply.
