Abstract

In power system operation, transient stability is an important index to measure whether the system can restore balance after a short time disturbance. With the development and complexity of power system, transient stability becomes one of the main factors threatening the safe operation of power system. In the transient stability theory of power system, the basic concept of power system stability is elaborated, the mechanism of transient instability is analyzed deeply, and a variety of transient stability evaluation methods are introduced. At the same time, the main factors affecting transient stability are discussed, including fault type, relay protection operation time, operation mode and load change, etc., which provides a theoretical basis for the subsequent analysis and control strategy. At the technical level, this paper introduces the traditional method of transient stability analysis and the modern numerical simulation technology, especially the application of variable step size integration method, high order numerical method and parallel computing technology, which significantly improves the analysis efficiency and accuracy. In addition, the paper also discusses the innovative application of artificial intelligence in transient stability analysis, showing the great potential of intelligent technology in this field.
