Introduction

Synchronous generators are a type of electrical machine that plays a crucial role in converting mechanical energy into electrical energy. These machines are widely used as a backup power source in various companies, both commercially and non-commercially, when there is interference with PLN networks. In a three-phase system, the installed load is often not in a balanced state, which can significantly affect the performance of the generator. Therefore, understanding the characteristics and efficiency of synchronous generators is essential to design a more efficient and reliable electricity system.

Characteristics of Synchronous Generators

Synchronous generators are designed to operate in a three-phase system, which consists of three windings connected in a specific configuration. The two most common configurations are the Delta connection and the Wye connection. In a Delta connection, the three windings are connected in a triangular shape, while in a Wye connection, the three windings are connected in a star shape. The choice of configuration depends on the type of load and the desired performance characteristics.

Voltage Setting Characteristics

The measurement results of the voltage setting characteristics indicate that the voltage settings in the Delta connections are greater than the voltage settings in the Wye connecting. The voltage regulation value in the Delta connecting reaches 71.73%, while the Wye connecting is only 52.45%. This shows that over time, voltage arrangements tend to decrease. Furthermore, the synchronous generator voltage settings with unbalanced loads in the delta connection also show better results compared to Wye connecting, with the highest average of 46.38% and 23.36% respectively. This data indicates that in unbalanced load conditions, generators with a Delta connecting configuration are more efficient in regulating voltage compared to Wye connecting.

Efficiency Analysis

Analysis of synchronous generator efficiency shows that efficiency at a balanced load with WYE connecting is higher than the Delta connection. At Wye's connecting load, the highest efficiency recorded is 64.85%, while the delta connecting load only reaches 50.25%. This shows that generators with Wye connecting configuration are superior in managing energy in balanced load conditions. Conversely, at unbalanced load conditions, generators with WYE connecting configuration also show better performance, with an efficiency of 64.95% compared to 54.95% in the Delta connection. This confirms that although unbalanced loads can reduce efficiency, generators with WYE connecting configurations still have advantages in terms of efficiency compared to delta connections.

Importance of Connecting Configurations

From the analysis above, it can be concluded that the selection of connecting configurations in synchronous generators is very important to achieve optimal characteristics and efficiency. Delta Connection Configuration offers advantages in the voltage settings at unbalanced load conditions, while Wye connecting configurations are more efficient in balanced or unbalanced conditions. Therefore, a deep understanding of the characteristics and efficiency of synchronous generators will help in designing a more efficient and reliable electricity system.

Conclusion

In conclusion, the analysis of changes in loads to characteristics and efficiency of three-phase synchronous generators highlights the importance of selecting the right connecting configuration. The choice of configuration depends on the type of load and the desired performance characteristics. Delta Connection Configuration offers advantages in the voltage settings at unbalanced load conditions, while Wye connecting configurations are more efficient in balanced or unbalanced conditions. Therefore, each electrical system voter needs to consider the conditions and type of burden to determine the most appropriate conjunctions configuration in order to maximize the synchronous generator performance.
