Summary:
A power system is a nonlinear dynamical system. Understanding the dynamic behavior of a power system is necessary for its reliable operation. K. Noda proposed an equivalent mechanical model of a power system to help intuitively understanding power system behavior obtained from a mathematical model of a power system. The validity of the mechanical model was confirmed qualitatively. This study quantitatively evaluates the mechanical model through experiments that assess the accuracy of its analogy with the mathematical model. To this end, the steady-state and transient stability limit of a power system are demonstrated. The limitation on the mechanical-mathematical model analogy is evaluated.
