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 output voltage on the bridge circuit or directly controlling its 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, ensuring the system power factor is always maintained at 0.99. Bidirectional reactive compensation range (capacitive and inductive), real-time adjustment based on system reactive power changes to prevent over-compensation or under-compensation issues. Active compensation output avoids common problems in traditional reactive 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 installations 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:可以根据系统实际电能质量现状，设置治理优先级，将模块利用率最大化
6. Parallel connection to the system with 16 protection functions for comprehensive equipment and system safety
7. User-friendly operating system, easy to understand, with a built-in electronic operation manual for随时查询
