Electrical Engineers and the Infinity in Power Systems

In the realm of power systems, infinity serves as a pivotal theoretical construct, facilitating the representation of extreme limits of quantities as they approach exceedingly large values. This theoretical framework simplifies complex problems and fosters creative problem-solving approaches for engineers. This paper explores the multifaceted role of infinity as a theoretical construct in power systems scenarios, showcasing how this abstraction harmonizes with the practical application of engineering principles. The discussion spans concepts such as the ground-potential and infinite bus as reference points, the significance of infinity in power lines analysis, the practical implications of short-circuits and open-circuits in power systems, and the continuity of state variables. By bridging the theoretical and practical aspects, this paper contributes to a comprehensive understanding of how infinity is harnessed as a tool in the field of electrical engineering, demonstrating its significance in simplifying intricate problems and advancing power systems design and analysis.
