Dynamic step-less power factor correction systems specifically designed to eliminate energy operator penalties in Colombian industrial grids.
Colombia is undergoing a major structural transformation in its electrical grid system. Spearheaded by the Mining and Energy Planning Unit (UPME) and supervised by the National Dispatch Center (XM), the national grid is transitioning rapidly from highly centralized hydropower generation toward decentralized solar plants in the northern Caribbean departments (Cesar, La Guajira) and wind energy hubs. While this shift enhances carbon neutrality, it places massive stress on system-wide grid stability. Non-conventional renewable energy (FNCER) introduces severe voltage fluctuations and rapid power swings. Under the strict mandates of the CREG 015 of 2018 Regulation (Comisión de Regulación de Energía y Gas), industrial consumers in industrial centers like Bogotá, Medellín, Cali, and Barranquilla face mounting penalties if their reactive power limits and harmonic injections exceed stringent thresholds.
The CREG 015 regulation strictly penalizes both excessive inductive reactive power and capacitive reactive power injection into the public network. Crucially, the penalty contains an accumulative hourly multiplier. If a facility does not correct its power quality within a rolling monthly cycle, the penalty costs can compound exponentially, turning power factor issues into major operational liabilities.
Historically, industrial plants relied on passive shunt capacitor banks to correct power factor. However, capacitor banks operate in fixed step configurations, introducing slow contactor switching delays (ranging from 10 seconds to minutes) and risk causing harmonic resonance. With modern variable speed drives (VFDs), welding equipment, and automated CNC machinery dominating Colombian manufacturing sites, load variations happen in milliseconds. Static Var Generators (SVGs), designed around active Insulated Gate Bipolar Transistors (IGBT) behaving as controlled current sources, offer sub-10ms response times. SVGs adjust dynamically to supply precise inductive or capacitive reactive current step-lessly, guaranteeing a steady target power factor (cos φ > 0.99) and ensuring zero risk of capacitive over-compensation penalties during off-peak hours.
Why modern grid infrastructures choose IGBT-based active compensators over traditional capacitor systems.
Full dynamic cycle response within 10ms (1/2 cycle of 60Hz grid standard used in Colombia), resolving instant voltage sags.
Dual action correcting both reactive power (leading and lagging) and filtering harmonics up to the 50th order concurrently.
Maintains target power factor at exactly 0.99, eliminating risk of reactive power over-injection penalties under CREG regulations.
The departments of Antioquia and Valle del Cauca host intensive manufacturing sectors, including metallurgy, chemical processing, plastics, and large textile mills. These industries operate heavy inductive motors, reciprocating compressors, and plastic extruders. The variable load profile creates sudden voltage dips and fluctuating power factor. High-voltage and low-voltage SVG configurations installed directly in utility substations stabilize voltage instantly and prevent production line interruptions while securing complete compliance with EPM (Empresas Públicas de Medellín) grid connection rules.
The port infrastructure of Barranquilla, Cartagena, and Santa Marta handles major bulk cargo and container terminals. Large gantry cranes, conveyor systems, and reefers draw highly fluctuating reactive currents that create voltage instability at the end of long transmission lines. Utilizing modular SVG solutions helps mitigate localized grid sag and handles rapid active/reactive switching, which reduces thermal stress on transformers and extends machinery lifespan in humid, high-salinity coastal environments.
In Bogotá and Cundinamarca, the rapid buildout of commercial real estate, tier-3 data centers, and municipal electric bus depots (such as TransMilenio fleet chargers) introduces high levels of non-linear loads. EV DC fast chargers and server power supply units are notorious for injecting high-order harmonics (primarily 3rd, 5th, 7th, and 11th orders) into distribution transformers. Modern modular Advanced Static Var Generators (ASVG) coupled with Active Power Filter (APF) functions counteract these harmonics directly on the zero line and correct power factor in real-time, preventing neutral cable overheating and avoiding costly utility penalties from Codensa (Enel Colombia).
In addition to power-grid scale SVGs, precision electrostatic charge regulators are vital for clean electronics manufacturing, plastic injection, and PCB processing lines across Colombia.
The next decade of power quality engineering centers on smart integration. Legacy SVG systems only corrected primary reactive currents. Modern technical roadmaps focus on integrating multiple power quality systems into singular hybrid setups. ASVG (Advanced Static Var Generator) systems now combine multilevel IGBT converters with active harmonic filtering and real-time phase balance functions.
| Feature Parameter | Traditional SVG | Advanced ASVG (Sowest Electric) |
|---|---|---|
| Reactive Compensation | Pure dynamic inductive/capacitive reactive correction | Dynamic correction plus fine-tuned step-less control |
| Harmonic Mitigation | None, or limited to low-order | Mitigates up to the 50th harmonic order (THDi < 3%) |
| Phase Imbalance Control | Basic correction capability | Full 3-phase load balancing for zero-sequence isolation |
| Response Time | 15ms - 20ms | Sub-10ms (Real-time DSP-driven IGBT triggering) |
| Modularity & Expandability | Rigid rack designs | Hot-swappable plug-and-play modular layout |
This technological roadmap supports easy integration with microgrids and energy storage systems (BESS). By using standardized communication protocols (such as Modbus RTU, Profibus, and IEC 61850), plant managers in Colombia can monitor power quality dashboards remotely via SCADA, allowing them to track active power factor correction, voltage profiles, and harmonic injection levels dynamically.

For any electrical panel or dynamic power factor compensator to operate legally in Colombia, compliance with RETIE (Reglamento Técnico de Instalaciones Eléctricas) is mandatory. RETIE regulations certify that the electrical assemblies, isolation distances, copper busbars, and safety systems prevent electric shocks, fires, and grid interference. All export-bound Static Var Generators manufactured by Sowest Electric undergo complete dielectric, heat-rise, and short-circuit testing, ensuring seamless pathing for local Colombian engineers during RETIE site audit approvals.

Expert answers to common queries regarding SVG installations under Colombian electrical standards.
While both rely on IGBT topology, their primary focus differs. An SVG is designed to correct fundamental frequency (60Hz) reactive power (leading and lagging), providing step-less reactive compensation. An APF is engineered to inject currents that cancel out high-frequency harmonic currents (such as the 3rd, 5th, 7th, 11th orders). Many modern modules combine both functions into an ASVG unit.
The CREG 015 rule penalizes plants that inject capacitive reactive energy during off-peak hours or draw excessive inductive reactive energy during peak hours. A traditional capacitor bank cannot react quickly to modern load profiles and can over-compensate, causing capacitive penalties. An SVG continuously tracks grid current and adjusts its output to ensure the power factor stays exactly at target (e.g. 0.99) with zero reactive power over-injection.
Yes, our equipment is built and tested to meet international IEC standards, which serve as the foundation for the Colombian RETIE certification. We supply all required design drawings, factory inspection sheets, and testing documentation to help your local certified engineers obtain RETIE site certificates smoothly.
Absolutely. A hybrid configuration is a highly cost-effective option for large industrial setups. In these systems, standard capacitor banks manage the base inductive load, while a smaller SVG covers the dynamic, fast-changing reactive load adjustments. This provides step-less compensation at a lower upfront investment.
Our SVGs feature optimized cooling paths and conformal coatings on PCBA boards, allowing them to operate reliably for over 100,000 hours. For high-altitude sites (such as Bogotá at 2,600m above sea level), we apply appropriate voltage and thermal de-rating factors to ensure stable and safe operation.
