The invention discloses an intelligent
power grid fault monitoring method and
system applying
artificial intelligence, and relates to the technical field of power
system fault monitoring, and the method comprises the steps: obtaining power internet-of-things
monitoring data through a sensor, carrying out the preprocessing of the data, extracting fault-related features based on the preprocessed data through a
machine learning
algorithm, and carrying out the fault-related features; based on historical data of the
power grid, a preliminary fault monitoring threshold range is determined through
statistical analysis; and comparing the fault
feature vector with real-time monitoring
power grid operation state data, dynamically adjusting a fault monitoring threshold value by using an
adaptive algorithm based on a comparison result of historical data and real-time state data of the power grid, giving an alarm after an abnormal condition is monitored, and optimizing a fault monitoring mechanism according to feedback of a fault
processing result. According to the invention, through data preprocessing,
noise removal is realized, the monitoring precision is improved, and the effect of improving the fault detection accuracy is achieved.
