Abstract

In this paper

the power system transient frequency stability is analyzed by Lyapunov direct method. It is pointed out the transient stability of the frequency is closely related to the position of the static characteristics of prime mover of generator under large disturbance

And if the system frequency is lower than the critical frequency

the frequency transient instability will occur when the system operates in the low frequency band with static characteristics.The critical frequency of transient stabilization and the estimated value of the attraction domain are obtained. It is of great significance to understand the transient operation characteristics and take measures to prevent the transient frequency instability for system design and operation personnel of power system.
