Method and system for online metering and real-time monitoring of electric transmission line

Abstract

The invention relates to a method and a system for online metering and real-time monitoring of an electric transmission line. The method comprises the following steps: a measurer (1) of the electric transmission line obtains the data of the electric parameter and the electric quantity parameter of the electric transmission line and / or the physical parameter of the electric transmission line by measuring, sends the parameters to a distant main station (3); a user-end metering module (2) obtains the data of the electric quantity parameter, the required quantity parameter and / or the electric parameter of the user by measuring and sends the data of the parameters to the distant main station; the distant main station (3) carries out data storage, comparison, statistic and / or analysis to the data of every parameter, achieves the purpose of the real-time monitoring of the electric transmission line and judges the abnormal electric utilization of the user; or the measurer (1) of the electric transmission line automatically judges the abnormal electric utilization of the user and sends the information of the abnormal electric utilization to the distant main station. The method for online metering and real-time monitoring of the electric transmission line has the advantages that the running state of the electric transmission line can be monitored in real time during the automatic management of the electric energy metering, such as the illegal electric utilization or the abnormal state of the scene of the electric utilization is alarmed, and the like.

Description

Technical field [0001] The invention relates to a variety of physical shapes of power transmission lines, especially electrical performance testing, and particularly relates to remote measurement and remote signaling technologies for sending data by digital remote communication and preventing abnormal power consumption. Background technique [0002] Today, with the continuous promotion and development of power automation management, online real-time monitoring and early warning of the operation status of the transmission line system is an urgent issue for the power system, which is related to the improvement of the power supply quality of the power system, the reduction of the operation failure rate and the timely failure Respond and exclude. At present, the monitoring of the transmission line system is achieved by measuring the electrical parameters of the transmission line in the substation. This monitoring method cannot perform online real-time monitoring of the transmission l...

Problems solved by technology

At present, the monitoring of the transmission line system is realized by measuring the electrical parameters of the transmission wires in the substation. This monitoring method cannot carry out online real-time monitoring of the transmission line, which is not conducive to the improvement of power supply quality, the reduction of operation failure rate and the failure rate. Timely Response and Troubleshooting

[0003] At the same time, the current power management departments generally face the problem of "anti-stealing electricity". Some power users are driven by interests and use various means of stealing electricity to illegally obtain economic benefits.

Various power management departments have adopted various anti-stealing methods. The existing anti-stealing methods generally carry out various technical treatments on metering boxes and meters. , many stealing behaviors cannot be completely discovered and avoided by existing monitoring methods
