Static Var Generator (SVG/STATCOM) Products

SVG works as a current source, which alerts the power factor of the grid with the reactive current generated by itself. SVG by CPT will check the load current through the external CT, and performs computing through the external DSP to analyze the reactive content of the load current. After that, it controls the PWM signal generator based on the settings to send control signals to the internal IGBT. In this way, it generates reactive compensation current to implement dynamic reactive power compensation.

CPT offers the SVG/STATCOM for both LV and MV voltage levels.

Voltage Regulation Mode and Var Control Mode (V-I Characteristic)

• The working range or operating area of STATCOM is limited only by the maximum voltage and current ratings of the converter.
• A STATCOM provides smooth voltage control over a wide range of operating conditions, has high dynamic and very fast response time, and always provides the maximum reactive current at any value of voltage.
