摘要：
Recent years, the monitoring and control of short-term voltage stability has drawn much attention of researchers and operators of power system. First, this paper introduces an online maximum Lyapunov exponent calculating method based on phase rectification, the advantage of which over traditional methods is that the calculation results of the algorithm doesn't rely on parameter settings. Then, this paper proposes a transient profile forecasting method based on MLE. Transient profile forecasting is able to reduce the degradation of performance reduced by different types of time delays of monitoring and control of short-term voltage stability. At last, the simulation work is introduced.
