Heavy Duty Advance Static Var Genrator Rack Type
Based on the principle of voltage source inverter, Elcosine Energia-ASVG Advanced Static Var Generator uses insulated gate bipolar transistor (IGBT) to control the magnitude and phase of inverter AC voltage, so as to achieve the purpose of reactive power, harmonic and imbalance compensation. Because the switching frequency of IGBT is very high (up to 25.6kHz), ASVG can compensate rapid reactive loads and achieve quite high compensation accuracy. ASVG have the best cost performance with the function of reactive power and harmonics control.
Introduction
EL-PQC-ASVG Advanced Static Var Generator
ELPQC-ASVG Advanced Static Var Generator (ASVG) 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.
ELPQC-ASVG can also compensate phase imbalance and harmonics. Compared with the traditional capacitor bank, ELPQC Advanced Static Var Generator has the advantages of fast response and high compensation accuracy without under-compensation or over-compensation problems, avoiding resonance, etc.
Modular Design
ELPQC series Advanced Static Var Generator has an advanced modular design. Usually ELPQC-ASVG consists of one or several ASVG modules and an optional touched LCD Human Machine Interface. Each ASVG module is an independent and dynamic reactive power compensation system, and users can change the SVG rating by adding or removing ASVG modules.
According to the mounting type, ELPQC Advanced Static Var Generator can be divided into Rack Modular ASVG, Wall-mounted ASVG and Free Standing ASVG.
