Transient Recovery Voltage Analysis of a 500-kV Transmission Line with Additional Series Reactors
Year: 2025
Type: article
Abstract: This study investigates the impact of series reactor installation on transient recovery voltage (TRV) and the rate of rise of recovery voltage (RRRV) in the 500 kV Suralaya–Suralaya Baru transmission line within the projected 2030 Java–Madura–Bali (JAMALI) power system. Using data from the PLN RUPTL 2021–2030 [21], the research evaluates how series reactors influence TRV and RRRV during a single line-to-ground or short-line fault occurring 5% from the Suralaya line. Simulations were conducted in DIgSILENT PowerFactory using detailed transmission line modeling that incorporates line coupling and stray capacitance, with model validation performed through power flow and short-circuit comparisons. Two scenarios, before and after the installation of series reactors, were assessed. Prior to installation, TRV was 872.9 kV and RRRV was 2.14 kV/µs, while after installation TRV increased to 922.2 kV and RRRV increased to 11.9 kV/µs. Although the TRV remains within IEEE Std C37.011-2019 limits [11], the RRRV exceeds the standard threshold, indicating the need for mitigation. The study’s novelty lies in developing a detailed Java–Madura–Bali system model in PowerFactory and applying network reduction to improve simulation efficiency. As the effects of series reactors on TRV and RRRV in this system have not been previously examined, the findings provide essential insights for ensuring circuit breaker reliability and supporting future high-voltage system planning.
