Introduction

Distributed Generators (DG) or Generator Scattered are small-scale power plant systems located near energy users (load sides) and connected to the distribution network. The existence of DG in the distribution network brings significant changes to the characteristics of more current, which in turn affects the performance of existing protection devices. In this article, we will discuss the study of the effect of DG interconnection on more current protection systems on a 20 kV distribution network.

Understanding Distributed Generators

DG interconnection in the distribution network results in changes in the level of more current disruption which can have a direct impact on the coordination of protection devices. Through the analysis and study of protection device coordination, we can understand more about how the existence of one or more DGs changing the way the protection device works in responding to the flow of disturbances. In this final project, the study focuses on changes that occur when the distribution network is connected to one DG or two DGs simultaneously, as well as in conditions where only one generator from the Active Micro Hydro Power Plant (PLTMH) is active.

The Impact of DG on More Current Protection

One important aspect in this study is an understanding of the amount of disruption flow that flows during interference in the tissue. This effect is very dependent on the setting of a protection device, including the characteristics of the more current relay curve used. For example, in conditions where only one DG is active, the amount of current flowing and the way the protection device responds to the current will be different compared to when two DGs operate simultaneously. This shows that there are significant differences in the coordination of protection devices that need to be considered.

The Challenges of DG Interconnection

The existence of DG can also weaken protection in certain parts of the distribution network if not managed properly. For example, protection devices may not function properly if the current current current generated by DG is lower than the threshold value that has been set. This requires a careful evaluation and calibration to ensure that any changes in network configurations can be balanced with adjustments in the protection system.

Analysis of the Results

Analysis of the results of this study shows the importance of conducting a comprehensive protection study before interconnecting DG into the distribution network. By understanding the interaction between interference currents and protection devices, we can ensure that the distribution system remains safe and reliable. Furthermore, this research also underlines the need for a holistic approach in the planning of electrical systems, especially in the era of energy transitions that increasingly prioritize the use of renewable energy sources.

Conclusion

In conclusion, more current protection in distributed generators intelligent in the 20 kV distribution network requires in-depth analysis to ensure system safety and reliability. Changes that occur in the coordination of protection devices due to DG is a crucial aspect that should not be ignored. With the right study, we can formulate effective and efficient protection strategies, so that the distribution system can operate optimally in the midst of various challenges and changes that exist.
