Description

technical field [0001] The invention relates to the technical field of automated production of modularized APF / SVG equipment, in particular to a multifunctional sampling and calibration device. Background technique [0002] With the increasing demand for power quality in the distribution network, the modularized APF / SVG (static var generator) is gradually being adopted due to its good dynamic continuous stepless adjustment of reactive power, three-phase unbalance compensation, and harmonic compensation. Users on the electricity side accept and put into use on a large scale. Compared with SVC devices and synchronous condensers, this type of device has many advantages such as fast reactive power response, small footprint, long service life, and simple operation and maintenance; due to the current module Hua APF / SVG is based on high-speed digital signal processing chip DSP and field programmable array chip FPGA control. All such devices need to calibrate their sampling data and...
