The static stability of a power system is of great significance to ensuring safety,stability,and reliable operation of power system.Based on the small disturbance analysis method,this paper proposes a criterion for the static stability of the power system.The single-machine infinite system,combined with the small disturbance signal model and excitation regulation system,is used to simulate the actual power system and establish a static stability simulation model.The simulation analyzes the speed change characteristics of the generator,evaluates the static stability of the system,compares and analyzes it with the static stability criterion,and verifies the correctness and feasibility of the static stability criterion.The research results can provide strong support for analysis and control of power system stability.
