New Design 75kvar Wall Mounted Svg Static Var Generator with Harmonic Filter Unbalance Crrection Function

SVG Operating Principle

SVG checks 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. 

Features
 
1.Wide compensation range, (+1) ~ (-1)
 
 
 2.Fast response speed, full compensation response speed ≤10ms
 
 
 3.Low-order harmonic compensation capability, can perform 3-13th harmonic compensation
 
 4.Three-phase unbalance compensation capability, which can adjust the three-phase imbalance of the system
 
 
 5.Flexible configuration, according to the actual power quality status of the system, set governance priorities to        maximize module utilization
 
 
 6.Connected to the system in parallel, with 16 kinds of protection functions at the same time, comprehensive protection of equipment security and system security
 
 7.Flexible expansion, combined with common reactive compensation capacitor cabinet for hybrid compensation
