The popularization and application of power users to digital electric equipment are more and more sensitive to the quality of electric energy, and the problem of the quality of the electric energy can cause the production line to stop production, thereby causing great economic loss. A bidirectional real-time interactive platform is established with a user, and the user is informed of the cost of power consumption, the real-time electricity price, the current condition of a power grid, planned power failure information and other service information in real time, which is also increasingly important. However, the centralized meter reading system operated in the current power system generally only collects the electric quantity information of the user, but does not collect the voltage, current, power factor, leakage current condition, residual electric quantity and other information of the user, and cannot realize intelligent and interactive management of real-time analysis and management of the electric energy quality of the user, prepayment management, demand side response, real-time electricity price management and the like. The negative control system only stays at a simple acquisition stage and does not have the function of direct interaction between a power grid and a user. The existing distribution transformer monitoring system can provide comprehensive distribution transformer power and electricity quantity information, but does not have a concentrator function, and cannot realize the functions of real-time line loss analysis, power quality control and the like of a distribution area. Generally speaking, the function configuration of each current real-time/quasi-real-time system is not perfect, information islands exist among the systems, the transverse integration and longitudinal communication of data are not realized, and the comprehensive data analysis and decision-making assistance functions cannot be provided for enterprise operation management; the intelligent level is low, can't realize the fine management and control of medium-voltage and low-voltage distribution network.
