description The invention discloses a relaying protection fixed value setting method based on an electromechanical transient method. The relaying protection fixed value setting method comprises the following steps: (1) acquiring data from a relaying protection setting software database and establishing positive-sequence, negative-sequence and zero-sequence algebraic equations of a power network; (2) combining electromechanical transient model parameters and solving simultaneous algebraic equation and a nonlinear equation by using an electromechanical transient simulation method to obtain dynamic process data of each status variable of a system in a fault process and after faults disappear; and (3) calculating a relaying protection fixed value according to the dynamic process information of each status variable in the step (2). With the adoption of the relaying protection fixed value setting method, the accuracy of a short-circuit calculation result can be improved, so that the accuracy of the fixed value calculation in a protection fixed value setting process is improved.
