Predictive synchronous machine transient state out-of-step discrimination method and predictive synchronous machine transient state out-of-step discrimination device

The invention relates to a predictive synchronous machine transient out-of-step judgment method and device, computer equipment, a storage medium and a computer program product. The method comprises the following steps: calculating a time domain unbalanced power track of a target synchronous machine based on real-time operation parameters of the target synchronous machine; when the time-domain unbalanced power trajectory at the current moment meets a preset prediction condition, calculating an acceleration area enclosed by the time-domain unbalanced power trajectory of an acceleration section and a time axis based on the acceleration section of the time-domain unbalanced power trajectory; calculating a predicted extended deceleration area corresponding to the current moment based on the deceleration section of the time domain unbalanced power trajectory; and if the acceleration area is greater than the predicted extended deceleration area, determining that the transient out-of-step prediction result of the syn
