The difference between SVG controllers and smart capacitors 2

Smart capacitors: Smart capacitors usually adopt open-loop control mode, which determines the timing of capacitor connection and disconnection through preset parameters and control strategies based on the load situation and power factor requirements of the power grid, thereby achieving reactive power compensation. diode

3. Response speed:

SVG controller: The SVG controller has a fast response speed and can adjust the injection or consumption of current in a few milliseconds or less to adapt to the instantaneous load changes and reactive power requirements of the power grid.

Smart capacitors: The response speed of smart capacitors is generally slow, and it usually takes tens of milliseconds or longer to complete the connection or disconnection operation of the capacitor. Therefore, in the case of rapid changes in grid load, compensation may not be completed in a timely manner.diode
