Abstract

The invention discloses a power quality wireless monitoring system. By setting a power quality analysis terminal and a plurality of power quality disturbance parameter acquisition nodes, it can be based on autonomous collection, independent processing and analysis of power quality disturbance parameters, and upload them to a remote server. Efficient analysis, identification and early warning of power quality. At the same time, by displaying power quality disturbance parameters in the form of a three-dimensional model of the power system, the visual display of the power system operation process is realized, which is convenient for the staff to monitor the collection nodes of each power quality disturbance parameter. Power quality, and timely warning of power quality.

Description

technical field [0001] The invention relates to the field of power monitoring, in particular to a wireless power quality monitoring system. Background technique [0002] There are a large number of nonlinear, impact and fluctuating loads in the power system, such as high-power frequency conversion equipment and drive devices, electrified railways, rectification equipment in the electrified industry, induction heating furnaces, electric arc furnaces, etc. These loads cause waveforms in the power grid Distortion (harmonic), voltage fluctuation, flicker, three-phase unbalance, asymmetry and other problems seriously degrade the power quality of the power grid. At the same time, precision electronic instruments based on computers and microprocessors are widely used in national economic enterprises, and their sensitivity to power supply quality is getting higher and higher, which puts forward higher requirements for power quality, so that power quality problems and their solutions...
