Application of Fault Tracing Paths Approach for Reliability of the Composite Power Systems

The usefulness of the well-built electrical power system is efficient supply generation of electrical power for consumers. For a reliability assessment of power systems, the system’s actual components in terms of performance and random behavior should be evaluated. This paper presents a reliability analysis based on the Fault Tracing Paths (FTP) method to identify component outages in composite power systems. This study focuses on composite power systems because these systems are linked to generating and distribution systems, in addition to having the primary equipment in these systems being used to move the electrical power. The FTP approach will identify the primary equipment that caused the composite power systems failure. This method gives out the events matrix for numerous flow Fault Tracing paths from the power sources to the loads. The proposed events matrix is applied as input data to simulate the system behavior. A power flow study is conducted using the RTS test system to evaluate the reliability of generators, transformers, and transmission lines during an outage. The study employs a simplified one-line diagram method to determine system stability and failure impacts. Finally, the proposed FTP method can be applied to complicated composite power systems.
