Transient stability of a synchronous machine described by voltage space vectors


STABILITY OF A SYNCHRONOUS MACHINE


A synchronous machine connected to an infinite bus is subjected to two consecutive step loads. A slight further increase in the load leads to instability and loss of synchronism. The bus voltage V and internal machine voltage E are portrayed in a synchronously rotating frame. The corresponding speed versus angle response is also shown.
