ATC-SVG Static Var Generator

Application:

Industrial manufacturing plants

Electric vehicle charging station systems

Large public buildings

Commercial buildings, data centers, hospitals, airports, and other facilities with high power quality requirements

Energy management and monitoring systems, sub-metering systems, and power SCADA systems

Functions:

Harmonic Compensation: Compensates for 2nd to 50th harmonics, supporting full-band or selective compensation
Power Factor Correction: Provides capacitive/inductive reactive power compensation with an adjustable target power factor (-1 to +1)
Three-Phase Unbalance Compensation: Dynamically adjusts three-phase currents to achieve load balancing
Dynamic Response: Response time < 10 ms, real-time compensation unaffected by system unbalance
Intelligent Algorithms: Supports FFT and intelligent dynamic compensation modes, switchable as needed
Modular Design: Supports rack-mounted and wall-mounted installation; single-module capacity ranges from 30 to 100 kvar; cabinet-based parallel capacity up to 500 kvar
Human-Machine Interface (HMI): 4.3-inch touchscreen supporting parameter configuration, real-time monitoring, fault alarms, harmonic analysis, and more
Communication Capabilities: RS485 + Modbus-RTU (Ethernet optional), supporting centralized monitoring
Protection Functions: Multiple protections including overvoltage, undervoltage, short circuit, inverter bridge reverse voltage, and overcompensation
