Introduction

In the world of electrical engineering, especially in the energy conversion system, the performance of the three-phase synchronous generator is one of the most important aspects. Changes in loads in the generator affect the stability and efficiency of the performance of the generator itself. In research conducted in the USU-FT energy conversion laboratory, an analysis of the effect of burden changes on the performance of the three-phase synchronous generator, as well as how the relationship between the load and the generator can affect the terminal and efficiency voltage.

Factors Affecting Generator Stability

The stability of the generator is strongly influenced by various factors, including the amount of connected load, excitation current, power factor, and the number of generator rotation. Instability often occurs due to major changes in the terminal voltage when the generator is connected to the load. Research shows that the synchronous generator voltage settings with Wye's relationship at a balanced load condition have better performance compared to the settings in the delta relationship. The voltage regulation in Wye's relationship is able to reach 90%, while the delta relationship only reaches 81%. This phenomenon shows that Wye's relationship is more effective in maintaining stress stability when faced with a balanced load.

Wye's Relationship: A Better Option for Balanced Loads

The results of the study indicate that the synchronous generator voltage arrangement with an unbalanced load shows different results. The voltage settings in the delta relationship turned out to be higher than Wye's relationship, with the highest average reaching 46% at the delta connecting load and only 18% at Wye connecting load. This shows that each relationship configuration in the generator has different characteristics in responding to changes in burden.

Delta Relationship: A Better Option for Unbalanced Loads

In terms of efficiency, this study also found that synchronous generators operating with a balanced load in WYE relationships produce higher efficiency, reaching 75%. Meanwhile, generators with the Delta connecting configuration only reached the highest efficiency of 42%. In terms of unbalanced loads, Wye's connecting generator efficiency is still superior with 68% achievements, while the Delta connecting generator records 57% efficiency. These numbers indicate that Wye's relationship configuration is more profitable in maintaining operational efficiency, especially in balanced load conditions.

Conclusion

Overall, this analysis provides an important insight into how changing loads can affect the performance of the three-phase synchronous generator. Understanding the right settings between the load and the generator can help in designing a more stable and efficient energy conversion system. This knowledge is very important for engineers and researchers in developing better generator technology in the future, as well as guaranteeing the continuity of operations in various load conditions.
