    Abstract: The disclosure discloses a dynamic stability analysis method and device for a linear time-periodic (LTP) system. The method includes the following steps. Calculate the Q matrix corresponding to the LTP system, and use the eigenvalue of Q matrix whose real part is positive as an instability eigenvalue. Each instability eigenvalue is subjected to the following steps. (S1) the state space model is transformed into the infinite-order harmonic state space (HSS) model, and the truncation order m of HSS model is initialized to 1. (S2) after m-th order truncation of the HSS model, its eigenvalue thereof is calculated. If the real part of the eigenvalue of HSS model is not the same as the real part of the instability eigenvalue, m is updated, and step (S2) is performed again; otherwise, modal participation factor analysis is performed to obtain the state variables that dominate the system instability.
