Intelligent dynamic monitoring system and method for power grid dispatching system

The invention discloses an intelligent dynamic monitoring system and method for a power grid dispatching system, and the system is provided with a filtering unit which firstly filters the bus voltage in each line in a power grid obtained in real time, filters the bus voltage of which the absolute value exceeds a first threshold value and exceeds a preset time length, and carries out the further voltage out-of-limit judgment on the basis. According to the method, bus voltage out-of-limit judgment is realized by adopting two levels of thresholds, so that stable operation of the system is ensured while the number of bus voltage out-of-limit alarm data is reduced. In addition, a prediction model is further arranged to achieve prediction control of the power grid dispatching system, the prediction model predicts and calculates the absolute value of the bus voltage after the set time length and the voltage change rate within the set time length to conduct comprehensive judgment, corresponding processing is conducte
