Description
Technical Field
[0001] The present invention belongs to the technical field of power grid dispatching, and in particular relates to a power grid dispatching dedicated network data electricity metering equipment system. Background Art
[0002] Power dispatching is an effective management method adopted to ensure the safe and stable operation of the power grid, reliable external power supply, and orderly progress of various power production tasks. The specific work content of power dispatching is to judge the safety and economic operation status of the power grid based on the data information fed back by various information collection equipment, or the information provided by monitoring personnel, combined with the actual operation parameters of the power grid, such as voltage, current, frequency, load, etc., and comprehensively consider the progress of various production tasks, issue operating instructions through telephone or automatic system, and command on-site operators or automatic control systems to make adjustments, such as adjusting generator output, adjusting load distribution, switching capacitors and reactors, etc., so as to ensure the continuous safe and stable operation of the power grid.
[0003] Therefore, in power dispatching, in order to ensure the safe and stable operation of the power grid, the accuracy of metering data is an important factor affecting the accuracy of power dispatching instructions. In the prior art, the user's electricity consumption data is mainly measured by electric energy meters, and the data is collected and transmitted to the dispatching end. In addition to the failure of the electric energy meter itself, the most important factor affecting the accuracy of the electric energy meter collection is the existence of electricity theft. The existing methods of electricity theft mainly include attacking the metering device, external signal interference, and attacking the metering / power supply line to steal electricity. Among them, the attack on the metering device is mainly aimed at electric energy metering devices such as electric energy meters or current transformers. The specific methods of electricity theft for electric energy meters mainly include opening the electric energy meter to short-circuit its internal components, opening the electric energy meter to install a remote control metering device, opening the electric energy meter to install or replace components such as resistors, short-circuiting the current sampling line of the electric energy meter in front of the metering chip, damaging the electric energy meter by punching or opening a skylight and short-circuiting the components in the meter or the end of the meter, etc., resulting in inaccurate or failure of measurement, thereby affecting the accuracy of power dispatching.
[0004] Without solving the above problems, the prior art usually adopts a protective box outside the metering device to prevent the metering device from being damaged by external forces and affecting the metering accuracy. This method mainly has the following problems: first, the electrical components generate heat during operation, causing the temperature inside the box to rise and affecting the operation; second, as the use time accumulates, dust easily accumulates on the internal electrical components. These problems will lead to an increase in the failure rate of the metering device, thereby affecting the metering accuracy, and the dispatching end cannot detect abnormalities in the metering data in time.
