Voltage instability is now under intensive study in Japan. It is very important to make clear the mechanisms of voltage collapse for the purpose of establishing the countermeasures.Voltage instability depends greatly on the dynamic characteristics of load and dynamic digital simulations are mainly adopted to analyze the dynamic phenomena of voltage collapse. In order to analyze the dynamic voltage stability, however, eigenvalue method has been already proposed by the authors, which requires a long computing time. In this paper, a simple method using “short-term P-Vcurves” is presented. It make it possible to show the power supply capability at any load nodes.A radial power system with 3 induction motors is analyzed and stability transition during voltage collapse is made clear. This phenomenon is useful for explaining the cascaded voltage collapse well.
