Abstract

A new algorithm simulating the impact of asynchronous torque to the transient stability of multi-machine power system is mentioned and some typical numerical examples are presented in this article. Based on the proposed algorithm this PC program uses the elements of the eigen-image matrix to bring the specific advantages for the calculations of the transient stability of multi-machine power system.The symmetrical and unsymmetrical transient voltages of the VAR supporting devices such as the static var compensators, synchronous machines are simulated under condition of action of the automatic voltage regulation system and the transient frequencies relating to the action of the asynchronous torque are simulated for analyzing of the transient stability in multi-machine power system.
