This paper discusses the causes of power system instability and the importance of fast fault clearing. The k-constant model is used to explain the relationships among the following: small signal stability, high impedance transmission lines, line loading and high gain, fast acting excitation systems. Various types of power system instability, utilizing both mathematical and practical approaches, are covered. Transient stability is discussed, including synchronizing and damping torques. The power…
