Abstract:The phasor measurement unit (PMU) time series data is effective in supporting the safe and stable operation of the power grid. Nevertheless, as the power grid dispatching and control cloud is constructed, services such as statistical analysis of data on power grid operation request the sharing of PMU time series data on the cloud. This study proposes a cloud-edge collaboration technology for such data. The technology builds an architecture of a data collaboration model according to the storage and access characteristics of PMU time series data so that data of this type are collected from the nodes at the edge of the production control area in the power grid dispatching system to the dispatching and control cloud and shared in a model manner. The feasibility of the proposed technology is verified through implementation and testing in a test environment.
