PQC-SVG Static Var Generator
PQC-SVG Static Var Generator detects load current in real time through internal and external CT and analyzes the reactive current of load by TI DSP and FPGA, then generates PWM signal to IGBT inverter(3 Level) to generate inductive or capacitive current and compensate reactive current to realize the target power factor. PQC SVG can also compensate phase imbalance.
Compared with the traditional capacitor bank, PQC-SVG has the advantages of fast response and high compensation accuracy without under-compensation or over-compensation problems, avoid resonance,etc.
Modular Design
PQC Static Var Generator has a advanced modular design. Usually PQC-SVG consists of one or several SVG modules and an optional touched LCD Human Machine Interface. Each Static Var Generator module is an independent and dynamic reactive power compensation system, and users can change the SVG rating by adding or removing SVG modules.
According to the mounting type, PQC Static Var Generator can be divided into Rack Modular SVG, Wall-mounted SVG and free landing SVG.
Model Description
PQC-SVG Static Var Generator Module series cover from 10kVAr to 100kVAr, support wall mounted type, rack type, free landing modules.
