In this paper, voltage stability index and the theories on voltage stability as well as WAMS` functions are proposed. The use of WAMS can help system to make quick measures to keep the voltage stability.
Wide-area measurement systems (WAMS) is a system to measure the parameters of the power system and deal with abnormal cases. Transient voltage stability is the ability that the system keeps the voltage normal after fault, which is very important to the power system.
