Intelligent power quality monitor terminal device

Abstract

The invention relates to power detection equipment, in particular to an intelligent power quality monitor terminal device, which comprises a sampling module, a setting module, a data storage and operation module, a communication module and an external control center, wherein the sampling module collects the date of a power grid, the data storage and operation module stores the collected power grid data, the stored data can be directly transferred to a communication module to communicate or processed by a date operation processing module to be then transferred to the communication module to communicate, the setting module sets parameters of acquisition and storage operations according to the communication data of the communication module, and the external control center manages and controls hardware devices at all levels for improving the power quality according to the communication data sent by the communication module. The invention can monitor the power parameters of a transmission line, a distribution transformer and a distribution line, integrates multiple functions of continuation, high speed, synchroballistic, active filtrating, three-phase load balancing, voltage flicker removal, voltage fluctuation and the like of reactive power into a whole, and thereby effectively improving the power supply voltage quality as well as the safety, stability and economic operation level of a distribution network.

Description

technical field [0001] The invention relates to electric energy detection equipment, in particular to an intelligent electric energy quality monitoring terminal equipment. Background technique [0002] When the power grid is in normal operation, the staff need to continuously monitor the power grid to know the specific situation of the power grid operation. The labor intensity is very high, and the work efficiency is not high; the power grid cannot be monitored and managed in real time when it is in normal operation, non-normal operation and accidents, and manual operation is required in the scheduling of electric energy. The limitation of electric energy dispatching makes it impossible to distribute electric energy reasonably, resulting in poor economic benefits of power grid operation and loss of electric energy. [0003] At present, the power supply bureau adopts the method of installing an electric meter for each household in the residential area to make statistics on t...
