本文提出了一种在输电线路跳闸、单相故障和三相故障等不同扰动下的同步发电机参数估计方法。发电机是专门建模的一组微分代数方程（DAE），允许参数估计从容易获得的测量，如终端电流和电压，磁场电压和机械速度。此外，一个新的配方的灵敏度分析被用作参数拟合算法。该公式避免了在估计期间DAE的代数方程中可能出现的可解性问题，并且在初始参数猜测远离真实值时保证收敛。估计过程中的噪声影响也进行了评估。
A methodology of parameter estimation of synchronous generator from different types of disturbances, such as: transmission line trip-out, single-phase faults and three-phase faults is proposed in this paper. The generator is specially modelled by a set of differential algebraic equations (DAE) to allow parameter estimation from easily available measurements such as terminal currents and voltages, field voltage and mechanical velocity. Furthermore, a new formulation of sensitivity analysis is used as a parameter fitting algorithm. This formulation avoids solvability problems, which can occur in the algebraic equations of the DAE during the estimation, and guarantee convergence when the initial parameter guess is far away from the true values. Noise influence in the estimation process is also evaluated.
