Abstract
The transient stability of multi-machine power systems is a critical aspect in ensuring the reliable and secure operation of electrical grids. This paper presents an in-depth investigation and analysis of transient stability in multimachine systems, focusing on identifying potential stability issues and proposing effective solutions. The paper begins by introducing the concept of transient stability and its importance in maintaining system resilience during disturbances. It highlights the challenges posed by the increasing complexity and interconnectedness of modern power systems, emphasizing the need for accurate transient stability analysis techniques. Various analytical methods and tools employed for transient stability analysis are reviewed. The advantages and limitations of each approach are discussed, providing insights into their applicability in different system scenarios. The paper also addresses the key factors affecting transient stability, such as generator characteristics, system topology, and control strategies. It explores the impact of various disturbances, such as faults, load variations, and network configuration changes, on system stability by determining the critical clearing time (CCT). Furthermore, it investigates the influence of protective devices, such as circuit breakers and relays, on transient stability and proposes strategies to enhance their coordination. To improve transient stability, the paper proposes Numerical integration techniques. The effectiveness of these techniques in enhancing system stability is evaluated through The six-bus power system network of an electric utility company that used as test system.
