The invention discloses a low-frequency oscillation parameter identification method based on an improved Prony algorithm. The original matrix inversion operation is replaced by a neural network; a matrix to be solved is used as a weight; the weight is adjusted through a gradient descent; a low-frequency oscillation parameter of the Prony algorithm is solved; repetitive solving of generalized inverse of a complex matrix is avoided; simultaneously, cyclical iteration is adopted; calculation is simply carried out; the precision is relatively high; whether a cost function is in a given precision range or not can be checked through correction of the weight; therefore, calculation is carried out more simply and effectively; operation of a synchronous phasor measurement device is optimized; and furthermore, reliable original data and data support are provided for functions, such as wide-area monitoring of an all-system power grid, automatic measurement and control of a transformer substation, steady control and self-adaptive relay protection.
