6kV Outdoor Type SVG (Static Var Generator)

Dimensions

• Quick Response, Leading Edge:

The full series uses instantaneous reactive power theory with a controller response time ≤1ms and full power response time ≤5ms, making it ideal for applications requiring strict reactive power response times, such as steel rolling, steelmaking, lifting, and impact loads.

• Negative Sequence Suppression, Balanced System:

The system compensates for negative sequence current caused by load imbalances, ensuring balanced three-phase current and improving power quality in the grid.

• Multiple Operating Modes:

Supports several operation modes to meet different needs: constant reactive power, constant power factor, constant voltage, negative sequence compensation, etc. It allows for online mode switching or custom curves as per customer needs.

• Harmonic Mitigation for Safety:

Effectively compensates for harmonics up to the 13th order, reducing risks of malfunctioning protection devices, capacitor module damage, transformer overheating, motor instability, and interference in communications.

• Long-Distance Power Transmission, Loss Reduction & Voltage Stabilization:

SVG devices installed on long transmission lines improve voltage, reduce losses, and provide quick reactive power regulation in fault conditions, enhancing system stability.

• Precise Compensation, Turning Penalties into Rewards:

SVG adjusts reactive power to keep the power factor at target levels, preventing penalties for low power factor or overcompensation that might cause instability in the grid.

• Comprehensive Protection, Worry-Free Operation:

Three levels of protection (device, system, and component level), with fast response times, safeguard the device from faults like overcurrent or overload.

• Full Recording and Smart Analysis:

Real-time monitoring of input/output current and voltage with waveform display, harmonic analysis, and easy access to system data for effective troubleshooting.

• Black Box Recording for Precise Diagnostics:

Automatically records 200 points (100ms) of data before and after protection actions for quick maintenance and fault diagnostics.

• Rich Interfaces, Plug and Play:

Supports Ethernet, RS485, CAN, and fiber optic communication interfaces, with protocols like MODBUS, ProfiBUS, and IEC61850 for remote monitoring and operation.

• Modular Design for Easy Installation & Maintenance:

Modular power units and control systems facilitate large-scale production and easy on-site installation and maintenance.

• Safety-Compliant & Easy Maintenance:

Designed for safe online operation without the need for downtime, making it easy to replace filters and check data while the equipment is running.

• Early Warning System, Hassle-Free Operation:

Monitors the temperature of each power unit, and triggers alarms if the temperature exceeds set thresholds, preventing issues like fan failure or filter clogging.

• Multi-Unit Collaboration, Easy Expansion:

Supports parallel operation of multiple SVG units for easy capacity expansion without system interruptions. In case of failure, the system automatically switches to parallel mode.

• Adaptability to Voltage Fluctuations:

SVG can automatically adjust to voltage drops or surges within the national standard range, resuming normal operation without manual intervention.

• Voltage Flicker and Fluctuations Suppression:

Effectively compensates for voltage fluctuations and flickers caused by load changes, such as arc furnaces, rolling mills, and compressors.

• Dual Power Supply for Stability:

Dual power supply options (380VAC, 2200VAC, or 220VDC) with hot-swappable, seamless switching in case of a power outage.

• Electromagnetic Compatibility:

The cabinet is designed with anti-interference features and passes EMC tests, ensuring reliable performance in electrically noisy environments.

• Dust and Water Protection (IP65):

IP65-rated equipment is available for harsh environments with high dust or humidity, offering superior protection.
