In this work, the speed smart control system is designed and implemented to improve and enhance the performance of hydropower system, where Arduino Uno R3 microcontroller is used for this propose. The speed smart control system is used to control the volume flow rate of water with respect to the load applied to the Pelton turbine shaft at optimum range of speed. Using nozzle outlet diameter of 8.87 mm. A water pump is used to generate the volume flow rate and pressure head. The results show that the maximum reduction in the hydraulic power was observed at zero torque, where the percentage reduction in the hydraulic power was equal to 87.33% when using speed smart control system. Also the optimum torque for maximum brake power and efficiency of Pelton turbine system have been increased when using a speed smart control system, where the percentage increasing was about 28.15%.Comparing result with and without using smart control system shows the percentage increased in the brake power and efficiency of Pelton turbine system were 26.3% and 35% respectively at the optimum torque for maximum brake power and efficiency of Pelton turbine system. Time response was four seconds to achieve a steady state for the rotational speed of Pelton turbine.
