摘要：

A method to analyze trajectory sensitivity of voltage stability based on quasi-steady state simulation is proposed, by which the sensitivity of system parameters control variables to state quantity can be attained. The trajectory sensitivity is utilized to predict the medium- and long-term trajectory in time-domain under the variation of control quantity and system parameters to assess voltage stability of power system, compare influences of power components on voltage stability and provide information to voltage stability control measures. Trajectory sensitivity method can remedy the defects of poor adaptability of traditional static sensitivity of voltage stability to device models and incapability of incarnating dynamic characteristics of power system as well as such shortcomings of traditional simulation methods as only simple information can be provided and poor analyzability of their conclusions.
