Product Description
The fundamental principle of the Static Var Generator (SVG) is to connect a three-phase bridge inverter circuit directly to the grid via a reactor. By appropriately adjusting the phase and amplitude of the AC-side output voltage or directly controlling the AC-side current, the circuit can generate the required reactive current to achieve reactive power compensation for the system. Supported voltage levels: 690V/480V/440V/400V/220V/110V.
Real-time tracking of system reactive power changes, linear compensation to ensure the system power factor remains at 0.99 at all times. Bidirectional reactive power compensation range (capacitive and inductive), with real-time adjustment based on system reactive power variations to prevent over-compensation or under-compensation issues. Active compensation output avoids common problems in traditional reactive power compensation equipment such as resonance, harmonic amplification, and low efficiency in low-voltage compensation.
Modular design allows for easy expansion, maintenance, and wiring. Flexible configuration and convenient installation, supporting wall-mounted and rack-mounted installation methods to adapt to various on-site requirements.
Advantages and Features
1. Wide compensation range: (+1) to (-1)
2. Fast response time: full compensation response ≤10ms
3. Low-order harmonic compensation capability: compensates for 3rd to 13th order harmonics
4. Three-phase unbalance compensation capability: adjusts system three-phase unbalance
5. Flexible configuration: allows setting governance priorities based on actual power quality conditions, maximizing module utilization
6. Parallel connection to the system with 16 protection functions for comprehensive device and system safety
7. User-friendly operating system with an intuitive interface and built-in electronic operation manual for easy reference
