1.Product Introduction

SVG series Static Var Generator is a reactive power compensation equipment with fast response speed and excellent compensation performance. Compared with traditional reactive power compensation products, this device has the advantages of high reliability, large compensation capacity, simple operation method and structure and good performance. In addition, the product complies with national standards such as GB7251-2013 and DL/T-1216-2013 and is the first choice equipment for reactive power compensation in power grid systems.

2.Working Principle

The Static Var Generator (SVG) takes DSP as the core and uses a command current calculation circuit and a current tracking control circuit to continuously detect the current and voltage of the system and perform a series of calculations and finally controls the inverter output through the PWM signal to the internal IGBT Compensation current to the system or grid. While quickly compensating the system's reactive power, the equipment can also eliminate power grid harmonics and solve power quality problems such as voltage fluctuations and flicker.
