Introduction

Partial discharge is a phenomenon of electrical release that occurs in the isolation medium between two electrodes that are not fully connected. This phenomenon is often an indication of damage to isolation, which can affect the performance of generators in power plants. The optimal generator performance is very important for the effectiveness and efficiency of power plants in meeting the energy needs in the area it serves. In this study, we aim to investigate the detection and analysis of partial discharge online at the Sicanang PLTGU gas turbine generator PT. PLN (Persero) Belawan Generation Implementation Unit.

Background of the Study

Damage to the isolation of generators is often caused by electrical failures that occur due to inappropriate temperature conditions or electrical charges at high voltage. Therefore, early detection of partial discharge activities is very important and must be done continuously. This aims to minimize damage to isolation and protect the equipment and systems as a whole. The importance of early detection cannot be overstated, as it can prevent costly repairs and downtime.

Methodology

In this study, partial discharge detection was conducted on the online gas turbine generator. This process involves measurements to analyze the causes, types, locations, and intensity of partial discharge. With the results of the analysis, the effect of partial discharge on the performance of the generator can be known more in depth. Through this measurement, important information is obtained regarding the condition of the generator, which allows preventive measures to be taken before a greater problem occurs.

Significance of Online Detection

Online detection partial discharge offers many advantages. One of them is his ability to provide real-time information about the condition of the isolation of the generator. This allows the technical team to immediately take action if there is a problem, so that the risk of further damage can be minimized. By using advanced technology, such as sensors and analytical software, measurements can be done automatically and continuously, making the monitoring process more efficient. This approach can significantly reduce the risk of equipment failure and downtime.

Power Loss Calculation

One important aspect that is considered in this analysis is the calculation of power loss caused by partial discharge. This power loss is an important indicator for understanding the impact of partial discharge on generator efficiency. When partial discharge occurs, the energy that should be used to produce electricity will be lost, thereby reducing the overall efficiency of the generator. The calculation of power loss is a critical step in understanding the economic impact of partial discharge.

Results and Discussion

Through this research, it is proven that the detection and analysis of partial discharge online is very important for the maintenance of gas turbine generators. By conducting early detection and in-depth analysis, the management of the power plant can optimize the performance of the generator and prevent greater losses. It is recommended that this practice is applied routinely in the maintenance process to maintain the reliability and efficiency of the overall power plant. Efforts to improve detection and analysis technology must continue to be carried out in order to face challenges and increase the competitiveness of the energy industry.

Conclusion

In conclusion, the detection and analysis of partial discharge online at the Sicanang PLTGU gas turbine generator PT. PLN (Persero) Belawan Generation Implementation Unit is a crucial step in maintaining the reliability and efficiency of the power plant. By using advanced technology and conducting regular measurements, the technical team can identify potential problems and take preventive measures to minimize damage to the equipment and systems.
