  The maximum amount that can be saved is 2*24*365=17520 kWh.
• The filtering performance is more refined and accurate:The harmonic compensation rate is increased to 97%, which means higher compensation accuracy and better compensation effect. The GRT-APFL model achieves a 97% harmonic compensation rate through higher switching frequency and control algorithm.The compensation rate of each harmonic can be set and the phase angle can be adjusted to achieve flexible and accurate compensation.
• High-density modular design:The internal structure of the module is more concise, reducing the weight and volume of the whole machine.Cabinets and modules take up less space.
• Silicon carbide power semiconductor devices have a thinner drift zone：High temperature resistance, and high thermal conductivity, which lowers the requirements for the cooling system of high-power modules. Higher switching frequencies make the size of peripheral electronic components such as inductors smaller, thereby reducing the overall size of the module. In addition, the thermal conductivity of silicon carbide semiconductor switches is more than three times that of silicon semiconductor switches, with stronger heat dissipation capabilities, reducing the requirements for the product's cooling system. Greater output power and stronger heat dissipation characteristics make the product lighter and smaller, suitable for more scenarios.100kvar rack type micro power static var generator Svg

The capacity of a single cabinet is increased to 160%.1200A, single cabinet capacity, can reduce the number of cabinets in multi-module parallel system.16 modules are controlled by a single controller, which enables integrated control of more modules and reduces solution costs.

 Fundamental Principle of BY92-SVG/30kvar-0.4/4L-N Static Var Generator

1.Dynamic reactive power compensation
BY92-SVG uses active current separation technology to detect and isolate harmonics and reactive components in real time29. By generating anti-phase inductive or capacitive currents, the device can achieve seamless compensation in the -1 to +1 power factor range, ensuring efficient energy utilization and compliance with grid requirements15.
2. Harmonic suppression and three-phase balance adjustment
In addition to reactive power compensation, the SVG can also reduce 2nd to 13th harmonics to address harmonic pollution caused by non-linear loads such as inverters and arc furnaces16. It integrates a three-phase unbalanced control system that detects unbalanced current and dynamically adjusts capacitive/inductive output to optimize load sharing, reduce neutral current and improve transformer efficiency47.
3. High efficiency and energy saving
The SVG uses H-bridge cascade topology and vector control technology to minimize switching losses and achieve an operating efficiency of over 98%. Compared with traditional SVC, it has a faster response speed (<5ms), a wider compensation range, and a smaller footprint, thereby reducing operating costs and improving system reliability.
4. Intelligent control and real-time monitoring
BY92-SVG is equipped with a dual closed-loop control system (DC voltage and AC current) to ensure stable DC bus voltage and adapt to grid fluctuations. Its intelligent control interface can monitor power parameters such as voltage, current, harmonics, etc. in real time, and supports remote configuration through the IoT platform, thereby achieving proactive maintenance and energy management.
