On-site measurement, control and protection integrated device of electrical micro-grid

The invention relates to the technical field of intelligent power grid protection, in particular to an in-situ measurement and control protection integrated device for an electrical micro-grid, which is provided with a data detection module, a sample storage module and a data processing module. The data processing module obtains the variation trend of the actual current data and the actual power data based on the average variation of the actual current data and the actual power data in a preset time period, and sends a data request to a sensor of the node based on a data request interval determined by the average variation; the data acquisition module is used for acquiring actual data, matching the acquired actual data with the data in the sample storage module to judge whether the power distribution network is abnormal or not, adjusting the determined data request interval based on the average variation under the first variation trend, and adjusting the determined data request interval under the second varia
