Abstract

The invention discloses a state estimation method and system for electric energy metering devices. The method comprises steps as follows: relevant estimated parameters of each electric energy metering device in a virtual network model are acquired; a domain model of all the electric energy metering devices in the virtual network model is built by utilizing all relevant estimated parameters; whether the state of each electric energy metering device is normal is judged by referring to the preset state estimation rule according to the domain model; when the states of all electric energy metering devices are normal, the state estimation result is normal; otherwise, the state estimation result is abnormal. The overall estimation process is automated and is automatically executed by relative programs in actual application, further, a computing method is simple, and the problems that the conventional state estimation method requires a large amount of manual intervention and complex computing process, the work efficiency is low and the reliability of the state estimation result is low are solved effectively.

Description

technical field [0001] The invention relates to the technical field of equipment state estimation, in particular to a method and system for estimating the state of an electric energy metering device. Background technique [0002] In the remote meter reading system used by the power company, in order to ensure the normal operation of the electric energy metering device and the reliability of the metering data, it is usually necessary to remotely estimate the operating status of the electric energy metering device. [0003] Existing state estimation methods often require a large amount of manual intervention and complex calculation process, the work efficiency is low, and manual intervention is prone to errors, resulting in low reliability of state estimation results. Contents of the invention [0004] In view of this, the present invention provides a method and system for estimating the state of an electric energy metering device to solve the problem that the existing state...
