Description

technical field [0001] The invention relates to the field of power quality monitoring and management in a low-voltage distribution network, in particular to a distributed grid-based online power quality monitoring and management system. Background technique [0002] In the power supply system, more and more load devices have nonlinear and time-varying characteristics. They act as harmonic sources to inject harmonics into the power grid, which seriously affects the power quality of the power supply network. Such as electrolysis, electroplating, and intermediate frequency furnaces in the metallurgical industry; welding machines, cranes, and punches in the machining industry; elevators and pumping units in energy industries such as mines and oil fields; As well as widely used frequency conversion air conditioners, these are non-linear loads that generate harmonics. They will inject harmonic power into the power grid or generate harmonic voltage on the public grid, causing the g...
