Abstract
The invention discloses a timing synchronization method used for an electromechanical transient simulation system and an electromagnetic transient simulation system. the method comprises the following steps: both the electromechanical transient simulation system and the electromagnetic transient simulation system receive first time reference, one of the two serves as the sending end to send synchronization signals transmitted via a first power line channel to the other serving as the receiving end, if a controller judges timing synchronization according to the transmission time of the synchronization signals, the receiving end sends first synchronization success signals to the sending end and the controller; if the controller judges false timing synchronization, the receiving end sends second synchronization success signals to the sending end and the controller after time is adjusted, and the sending end sends third synchronization success signals to the controller after the first or the second synchronization success signals are received. A middle adjuster and a synchronization signal carrying speed detection module are arranged between the sending end and the receiving end, and when the speed detection module detects that the speed of the synchronization signal exceeds the preset speed threshold, the middle adjuster carries out acceleration or deceleration processing.
