Introduction

Hydroelectric Power Plant (PLTA) is one of the main sources in the generation of electrical energy in the world, especially in Indonesia. In 2006, the data showed that almost 20% of global electricity needs came from the hydropower plant, which also contributed around 88% of the total renewable energy sources used. The development of water turbines has been a crucial aspect in the generation of electricity, and one of the important achievements in this field is the discovery of a reaction turbine by Jan Andrej Seignr in the middle of the 18th century. This turbine has a horizontal axis and is an inspiration for the development of further water turbines. Then, in 1849, James B. Francis succeeded in increasing the efficiency of reaction turbines by more than 90% and developed technical methods for water turbine designs, which came to be known as Francis turbines.

The Importance of Francis Turbine in Hydroelectric Power Plant

The Francis turbine is a type of reaction turbine that is widely used in hydroelectric power plants due to its high efficiency and reliability. In its operation, the Francis turbine must work optimally to ensure that the power plant operates efficiently and effectively. The Francis turbine is a critical component of the power plant, and any issues with its performance can have a significant impact on the overall efficiency of the plant. Therefore, it is essential to study the effect of various factors on the performance of the Francis turbine, including the steering examination opening.

The Effect of Steering Examination Opening on Head Losses

The steering examination opening is a critical component of the Francis turbine that affects the head loss and performance of the turbine. The head loss is the difference between the total head and the pressure head, and it is an important factor in determining the efficiency of the turbine. The results of the study show that the head loss will increase along with the wider the director's opening opening. The lowest head loss is measured at 102 mm openings with a value of 1,955684 m. Conversely, the head loss reaches the maximum value at 195 mm openings, which is 10.251029 m.

The Effect of Steering Examination Opening on Performance of Francis Turbine

The performance of the Francis turbine is affected by the steering examination opening, and the results of the study show that the efficiency of the turbine tends to increase with the increase in the director's opening. However, in 195 mm openings, turbine efficiency has decreased to 95.08485631%. The maximum efficiency is achieved at 191 mm openings, which gives an efficiency value of 95.99840019%. This indicates that the optimization of the steering blade opening is very important to improve turbine performance.

The Importance of Optimization of Steering Blade Opening

The optimization of the steering blade opening is crucial to improve the performance of the Francis turbine. The selection of appropriate openings not only affects the head loss but also the overall efficiency of the system. This study emphasizes the need for further adjustment and testing to ensure that the turbine operates in optimal conditions, especially in facing the challenges of varied water resources.

Conclusion

With a deeper understanding of the influence of the director's opening opening on the head loss and the efficiency of the Francis turbine, it is expected to improve the performance of the hydropower plant and make it a more reliable and efficient energy source. This is in line with global efforts to accelerate the transition to renewable energy sources, especially in countries that have large water resource potentials such as Indonesia.
