This article proposes a method for determining the optimal reclose scheme in power systems. The proposed approach involves analyzing multiple parameters such as the voltage and phase angle difference between bus, critical clearing time (CCT) of the systems, power surge of connected generators in the system, secondary arc duration in the systems, fault-induced delayed voltage recovery (FIDVR) phenomenon, and transient recovery voltage (TRV) in circuit breaker. Each parameter is assessed individually, and the results are compared with a matrix scoring system to determine the appropriate reclose scheme for each parameter. Subsequently, the reclose schemes derived from each parameter are integrated to identify the most effective reclose scheme for each segment of the system. This approach ensures that all relevant factors are considered in selecting a reclose scheme that optimally balances the system’s stability, reliability, and performance under various conditions. This methodology provides a more robust reclose scheme by considering a comprehensive set of factors, leading to enhanced the system stability and reliability. This study utilized DIgSILENT PowerFactory, providing a detailed examination of the Batam-Bintan transmission system. It is shown that the proposed method shortens the deadtime by 2 seconds in most single-phase reclosing schemes and 1 three-phase scheme, and mitigates the system instability risk on 3 three-phase reclosing schemes. The method presented serves as a valuable guide for determining optimal reclose schemes in both distribution and transmission systems, contributing to more effective fault recovery strategies and improved network performance.
