What is Reactive Power? In power systems, electric power is typically divided into three types: Active Power (P): The real power used to perform work (e.g., running motors, lighting). Reactive Power (Q): Power that does not perform work but is essential for generating and sustaining electric and magnetic fields. Apparent Power (S): The vector sum of active and reactive power. S² = P² + Q² Think of reactive power as the energy used to "set up the stage"—it doesn’t perform the task directly but is vital for the show to run. Types of Reactive Power Inductive Reactive Power: Generated by inductive loads like motors and transformers. It causes current to lag voltage. Capacitive Reactive Power: Generated by capacitive equipment such as capacitors or long transmission lines. It causes current to lead voltage. Modern power systems typically contain more inductive loads, which may result in excessive reactive demand, lowering voltage and power factor. Why Is Reactive Power Compensation Important? To maintain system stability and energy efficiency, reactive power must be managed with compensation devices such as Static Var Generators (SVGs), which help to: Improve power factor Reduce line losses and transformer stress Prevent voltage dips and collapse Comply with grid interconnection standards FGI’s Role in Reactive Power Management FGI develops advanced power electronics including SVG systems that offer real-time, precise control of inductive and capacitive reactive power across LV and HV networks.

 What Is Power Quality? Power Quality refers to how “clean” and “stable” the electricity supply is. It determines whether the voltage and current are within ideal ranges, stable in frequency, free of distortion, and properly balanced across all three phases. A system may have electricity flowing, but if the quality is poor—fluctuating voltages, harmonics, low power factor—it can silently damage equipment, reduce productivity, and cause hidden costs. What Are the Core Elements of Power Quality? Factor What It Means Common Effects Voltage deviation Overvoltage or undervoltage Motor overheating or torque loss Flicker Rapid voltage variation Light flickering, eye fatigue Frequency variation Non-50Hz/60Hz supply Misfunction in precision devices Harmonics Signal distortion from nonlinear loads Equipment overheating, control failures Unbalance Unequal voltage or current in phases Reduced motor lifespan Low power factor Excessive reactive power Utility penalties, extra losses   Why Is Poor Power Quality Often Overlooked? No immediate outage, but causes gradual damage Looks “normal” but fails internally Hard to trace the exact cause Extra electricity costs are misjudged as unavoidable Just like high blood pressure—it’s a silent killer for electrical systems. Who Is Most Affected? Industries highly sensitive to power quality include: Factories with many motors/inverters/welders Semiconductor, precision manufacturing, medical facilities Sites with BESS, solar PV, or wind generation Industrial zones with old infrastructure Commercial centers and data centers Case Insight: Inductive vs Capacitive Loads Inductive loads (e.g., motors) → Absorb reactive power → Lagging current → Lower PF and grid stress Capacitive loads (e.g., cables, capacitors) → Supply reactive power → Leading current → Risk of voltage rise Balancing inductive and capacitive reactive power is key to stable grid operation.

In today’s power systems, Voltage Instability, Power Factor Issues, and Reactive Power Imbalances are common challenges, especially with the rising penetration of renewable energy and heavy industrial loads. To address these issues, SVG (Static Var Generator) has emerged as a powerful solution, offering dynamic reactive power compensation and stabilizing grid performance.         What is SVG?   SVG (Static Var Generator) is a current source-based device designed for dynamic reactive power compensation. Unlike traditional VSC (Voltage Source Converter), SVG operates by injecting or absorbing current in real time to stabilize voltage and improve power factor.             Simple Analogy   · Imagine the power grid as a river where the water level represents voltage. · SVG acts like a smart pump, dynamically injecting or absorbing water (current) to keep the water level stable. · By adjusting the current, SVG compensates for reactive power and regulates the power factor, ensuring optimal grid performance.     Key Benefits and Functions of SVG   1. Real-Time Voltage Stabilization In grids with renewable energy generation or large industrial loads, voltage fluctuations are frequent. SVG responds within milliseconds by dynamically injecting current, stabilizing voltage, and preventing sags or surges.   2. Reactive Power Compensation and Power Factor Correction In industries like steel, cement, and mining, large inductive loads reduce the power factor, leading to higher energy costs. 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. Enhanced equipment protection by preventing voltage dips.   3. Grid and Transmission Line Stability In long-distance power transmission, SVG improves: Voltage stability during load variations. Power factor regulation, reducing line losses. Grid reliability by preventing voltage collapse.       Future Trends and Development   As power grids become more complex, SVG technology is evolving towards higher efficiency and smarter control systems: Grid-forming SVG: Future SVGs will offer grid-forming capabilities, enhancing microgrid stability and supporting weak grids. AI-powered optimization: Integration of AI algorithms for predictive control and automated compensation. Higher capacity and modular design: Scalable SVG systems for large-scale power plants and high-voltage applications.       Conclusion   SVG plays a crucial role in power quality management, offering fast, accurate, and dynamic reactive power compensation. Its current-source design makes it highly effective in stabilizing voltage, regulating power factor, and improving grid performance.                                     Production Base: North of the middle section of Jincheng Road, Economic Development Zone, Wenshang County R&D Center: No. 21, Gongye North Road, Baoshan Sub-district, Licheng District, Jinan City Email: overseas@fengguang.com   Website: www.fengguang.com.
