SVG injects current in phase with the voltage to compensate for reactive power, keeping the power factor close to unity. This reduces energy losses and improves grid efficiency.​   3. Current Injection for Grid Stability Since SVG is a current source-based device, it can: Dynamically adjust the current amplitude and phase to achieve precise voltage regulation. Provide leading or lagging reactive current to balance grid voltage and reduce flicker.​   4. Fast and Precise Response Compared to traditional devices like SVC (Static Var Compensator), SVG offers: Faster compensation speeds (within milliseconds). More accurate current control, ensuring precise voltage regulation. Compact design with modular scalability, making it ideal for diverse applications.       Application Scenarios and Use Cases   1. Renewable Energy Integration In solar and wind farms, intermittent generation causes voltage fluctuations. SVG: Injects or absorbs current in real time to stabilize voltage. Improves power factor compliance with grid codes. Enhances grid reliability, reducing voltage flicker.   2. Industrial Power Quality Management Heavy industrial loads often lead to voltage drops and low power factors. SVG provides: Dynamic current compensation, stabilizing voltage and improving power factor. Reduced energy costs by minimizing reactive power penalties.

High voltage filter capacitor (FC) device Product Overview The high-voltage harmonic filter is a passive filtering device specifically designed for high-voltage grids to mitigate harmonic frequencies, including the 3rd, 5th, 7th, 11th, 13th, and higher orders. It is particularly suited for environments with high harmonic generation, such as medium-frequency furnaces, arc furnaces, rolling mills, and rectifier equipment. The filter operates by using a series resonance circuit formed by filter reactors and capacitors to absorb harmonics effectively. This prevents harmonic currents from flowing back to the power transformer and into the grid, significantly reducing harmonic levels across the network. Additionally, it improves the performance of power transformers by reducing power consumption and enhancing the reliability of equipment and other electrical components. Moreover, the device provides a certain amount of reactive power compensation, thereby increasing the operational efficiency of the user’s load. Each system is custom-designed to meet specific customer needs, ensuring optimal harmonic filtering and reactive power compensation, enhancing load efficiency, and maximizing investment returns. Components and Principles The system consists of several FC single-tuned and high-pass filter branches, with each branch comprising filter capacitors and reactors. These components effectively absorb targeted harmonic frequencies, achieving significant harmonic reduction within the system. Main Technical Specifications Standards: GB50227-95, GB3983-89, JB7111-93, GB/T 14549-93 Ambient Temperature: -10℃ to +55℃ Relative Humidity: < 90% RH (at 25℃) Rated Voltage: 6–35 kV Filtering Frequencies: F5, F7, F11, F13 (determined based on site conditions) Harmonic Absorption Rate: > 85% Power Factor at PCC (Point of Common Coupling): > 0.92 Installation: Suitable for indoor and outdoor setups Structure: Cabinet-type, open configuration   Combined Compensation Method SVG + FC Why use SVG + FC? Although an SVG (Static Var Generator) can achieve both reactive power compensation and harmonic mitigation, using it alone for harmonic mitigation in environments with high harmonic content may lead to relatively high initial investment costs. Frequently fluctuating with large loads can cause severe disturbances in the power grid. Situations such as electric arc furnaces, electrified railways, induction furnaces, rolling mills, and renewable energy sources like solar and wind generation create such disturbances. These shock loads can lead to voltage fluctuations in the grid. Even a low-power electric arc furnace connected to a low short-circuit capacity grid can cause voltage fluctuations, flicker (and sometimes even frequency fluctuations), and three-phase voltage imbalances, which can negatively impact the reliable electricity usage of other grid-connected users. Combining SVG with passive filters (FC) not only filters out harmonics but also provides partial capacitive reactive power, reducing the overall equipment investment in the system. This combination offers an optimized, cost-effective compensation solution. Typical Application Fields The periodic changes in high-power rolling mill loads can cause severe voltage fluctuations, especially when multiple mills operate simultaneously, leading to increased randomness and significant long-cycle flicker. Traditional compensation devices, unable to adapt to load variations, not only fail to improve power factor but may even exacerbate voltage fluctuations. Power systems with these load characteristics require active dynamic reactive power compensation devices with both fast compensation and filtering capabilities to manage power quality, reducing grid disturbances and pollution. Each dynamic compensation method has its advantages and disadvantages; however, for these types of loads, an active dynamic reactive compensation system (SVG+FC) offers better performance, cost-effectiveness, and compensation effect compared to other control methods. The active dynamic reactive compensation system includes a Static Var Generator (SVG) and a Passive Filter (FC). The SVG provides continuously adjustable inductive and capacitive reactive power, effectively suppressing voltage fluctuations and grid flicker and improving three-phase imbalance. The FC filters out harmonics that need to be managed, reduces grid pollution, and provides capacitive reactive power needed by the system. Due to the superior advantages of active dynamic reactive compensation devices, over 90% of wind and photovoltaic generation installations have adopted this system for reactive power compensation in recent years. This ensures they deliver stable voltage and high-quality power with minimal harmonic content, making it the ideal dynamic reactive compensation solution today.
