Abstract:With the continuous development of the Internet of Things technology, the current power system has accumulated a large amount of heterogeneous data. The smart meter status evaluation method has problems such as poor combination, low generalization, and poor real-time performance. The method for real-time evaluation of universal smart meter status based on ubiquitous power internet of things can effectively solve the above problems. Based on the decision engine, the paper evaluates the state of the smart meter, and The acquisition data feedback is used to optimize the deployment of sensing devices in the ubiquitous power Internet of Things, so as to realize real-time, universal and accurate operation and maintenance evaluation of smart meter operation status. Further solve the problems of insufficient deployment experience of field equipment and verification without targets, and improve the scientific and effective operation of the power grid.
