Substation electric quantity and electric energy quality integrated management system

Abstract

The invention relates to a substation electric quantity and electric energy quality integrated management system. The system comprises a plurality of electric energy meters with harmonic monitoring functions for performing electric quantity, voltage harmonic and current harmonic monitoring on three sides or two sides, all incoming lines and all outgoing lines of a main transformer of the substation; a plurality of voltage quality index monitoring devices installed corresponding to the main transformer of the substation and used for performing the voltage type index monitoring on the main transformer of the substation; a server respectively communicated with each electric energy meter and each voltage quality index monitoring device and used for accomplishing the acquisition and management of the electric energy data and the voltage quality data. Each electric energy meter and each voltage quality index monitoring device are connected with the server via an acquisition device and through an electric power local area network. The system disclosed by the invention improves the intensive management level of the substation, capable of reducing the equipment configuration of the substation, and lowering the construction investment of the substation.

Description

technical field [0001] The invention relates to an integrated management system for substation power quantity and power quality integrated with substation power collection management and power quality monitoring management, and belongs to the fields of power collection technology and power quality detection technology. Background technique [0002] Substation electric energy acquisition management is based on the acquisition technology of the metering data of the substation electric energy meter, including the three sides (or two sides) of the main transformer of the substation, the metering data of the incoming line and the outgoing line, etc. for the collection, calculation and analysis of the electric energy meter. [0003] The management of substation electric energy is the basis of line loss management of power supply enterprises, the basic management work of implementing loss reduction and energy saving, and the basis of internal economic accounting.

AI Technical Summary

Problems solved by technology

[0006] Substation power collection management and substation power quality management are under the current technical background. The above-mentioned functional parts use their own independent servers, network channels, and terminal equipment to complete their respective system functions, which makes the equipment configuration in the substation complicated and requires a large investment. , it is difficult to achieve intensive management
