Power grid system and a method based on the detection sensor network

The present invention provides a detection method based on the power grid sensor network, said method comprising the step of detecting abnormality, a node reporting step, the step of reporting clusters, cluster reset step, the step of updating the dynamic clusters and cluster merging step. The present invention further provides a power grid detection system execute the above method. When the sensor nodes detect the relative importance of the abnormal state, the present invention can achieve real-time abnormal data upload, it reduces transmission delay; Furthermore, the present invention may also be integrated nodes belonging to the same abnormal region under the same cluster group, facilitate centralized transmission, management and application of abnormal data, and reduce the impact on other nodes other than the abnormal region.
