Abstract

The use of bank capacitors in an effort to increase the power factor in power quality issues, has several problems to be aware of. Switching capacitor banks during energization can cause transient surges related to transient voltages and currents. This study discusses the simulation and analysis of more transient voltage due to the switching of bank capacitors that occur in riau transmission line 150 kV using MATLAB Simulink 8.7. The effect of transient state when switching capacitor banks can have a detrimental impact, both for equipment and the system as a whole. Use Synchronous Closing Breaker as one solution to solve this problem. By using Synchronous Closing Breaker can reduce the voltage more in the transient state and dampen the oscillations that occur. The result of simulating the transient voltage value produced on Garuda Sakti bus reaches 1.35 pu, and the use of synchronous closing breaker method can reduce the transient voltage up to 1.04 pu. To reduce transient oscillations, it can also reduce transient current from a value of 532.2 A can be reduced to 476.1 A. The percentage of transient voltage reduction of synchronous closing breaker usage is 22.96%.Keywords: Electric Power System, Transient, synchronous closing breaker, Matlab R2016a/Simulink.

Abstract

This study addresses the challenge of transient voltage and current surges caused by capacitor bank switching in high-voltage transmission systems, which can compromise equipment integrity and system stability. The research focuses on optimizing the mitigation of these transients in a 150 kV transmission line using the synchronous closing breaker method. Simulations were conducted in MATLAB/Simulink using actual parameters provided by the power utility. To verify the accuracy of the Simulink model and its results, validation was performed in DIgSILENT PowerFactory by comparing steady-state voltage responses following capacitor switching. With the model validated, three operating scenarios were examined: no capacitor bank, conventional capacitor bank switching, and with the implementation of synchronous closing breakers. The synchronous closing method significantly reduced transient voltage and current magnitudes compared to conventional switching. These outcomes confirm the effectiveness of the synchronous closing breaker in minimizing transient disturbances. The findings contribute to the development of improved transient mitigation strategies and offer a practical reference for large-scale capacitor bank deployment, particularly in smart grid applications. This method provides a cost-effective and scalable approach for improving power quality in modern high-voltage transmission networks.
