Research On Operation And Maintenance Of 110kV And Above Unattended Substation Energy Metering Devices In Qingyuan

The electric energy metering runs through the entire process of electricity from generation to sales.Every technological innovation of the power grid is also closely related to the progress of electric energy metering.The development of smart grid has also put forward higher requirements for electric energy metering: intellectualization,informatization and standardization.Grid metering automation plays a fundamental role in the field of intelligent power consumption,and it is also the core component of the field of intelligent power consumption technology.At present,there is not a unified mode for the application of electric energy metering operation and maintenance in our country.Starting from the investigation of the situation of 110 kV and above unmanned substations in Qingyuan area and the current situation of power metering,this paper excavates the existing problems of power metering operation and maintenance,and studies the key work of field operation and maintenance of power metering devices in substations.The non-linear load and small hydropower metering methods are simulated and analyzed by wavelet transform,and the improvement measures are put forward.At the same time,the single terminal operation and maintenance mode of market-oriented transaction user measurement points is reformed,and the experimental application verifies the effect.Finally,the concrete conception and rationalization prospect of the next application of substation electric energy metering operation and maintenance are put forward.
