The LV/MV STATCOM (Static Synchronous Compensator) is a power-electronics-based reactive power and voltage support system. Unlike traditional capacitor-based compensation systems, a STATCOM injects or absorbs reactive power through a high-speed inverter structure, allowing millisecond-level response to load changes and precise voltage regulation on the connected bus.
Modern LV and MV distribution networks face significant challenges due to harmonics, sudden load variations, and the fluctuating nature of renewable energy generation. The STATCOM addresses all of these issues through its high dynamic response capability, ensuring stable operation and improved power quality for industrial facilities and utility networks.
Inrush STATCOM units utilize SiC MOSFET or IGBT-based multilevel inverter topologies to deliver a compact, high-efficiency solution. The hybrid DSP/FPGA real-time control platform enables precise current regulation, fast PLL synchronization, grid-forming functionality, and adaptive harmonic compensation.
Inrush STATCOM systems are built on advanced power electronics architectures and high-speed digital control algorithms. At the core lies a multilevel inverter topology (NPC / ANPC / MMC), providing:
The use of state-of-the-art SiC MOSFET devices allows high switching frequencies, providing wider control bandwidth, improved efficiency, and reduced losses—especially when paired with medium-voltage step-up transformers.
The STATCOM control platform is built on a hybrid DSP + FPGA architecture. The FPGA handles high-speed current sampling, PWM generation, and protection logic, while the DSP manages voltage regulation, PLL synchronization, and real-time power factor computation.
Inrush STATCOM units comply fully with international power quality, safety, and electromagnetic compatibility regulations. All systems are designed and tested according to the following standards:
For medium-voltage applications, the STATCOM is supplied with MV isolation transformers that comply with IEC 60076-11, including dielectric strength, thermal performance, and short-circuit withstand tests.
STATCOM systems are widely used in industrial facilities and MV distribution networks due to their fast dynamic performance. Key application areas include:
With its wide application range, a STATCOM increases energy efficiency, minimizes process interruptions, and significantly improves the voltage stability of facilities located in weak grid regions.
