Dowei Electric Static Var Generator SVG-STATCOM

Product catalog summary

General Description:
The Static Var Generator (SVG/STATCOM) by Ningbo Dowei Electric Co., Ltd. is designed for centralized active harmonic compensation and dynamic reactive power compensation for both inductive and capacitive loads. It offers continuous variable reactive power output with a rapid 5ms response time, making it ideal for dynamic loads such as rolling mills and arc furnaces. The system provides voltage stabilization, load unbalance compensation, and harmonic filtering, integrating extensive protection mechanisms.

Specifications:

Standards Compliance: IEEE 519, IEC 60871, IEC 60076-6, IEC 62271, NEMA, ISO 9001, KEMA, CESI, CE, TUV, UL, ASTA.
Seismic and Structural Design: Complies with ETGI-1.020, IEEE Std 693, NCh2369, ASTM A325, ANSI/AISC 360, AWS D1.1.
High Altitude Correction: Up to 5000m as per IEC 62271 & IEEE C37.

Typical Specification:

General Parameters: Rated voltage ranges from 3.3kV to 35kV with a voltage tolerance of 120%. Frequency is 50/60Hz, and capacity is up to 30Mvar per unit.
Output Performance: Complies with IEEE-519 for harmonic content, with a response time of 5ms and a targeted power factor of ≥0.95. Power loss is ≤1%.
Power Module Design: Utilizes a modular multi-level converter (MMC) with H-bridge inverter technology and IGBTs. All modules are interchangeable.
Control System Design: Features FPGA+DSP+ARM processors, optical fiber internal communication, and a 10-inch true-color TFT touch-screen HMI. Supports multiple languages and communication protocols including MODBUS and TCP-IP.
Protections: Includes over-current, IGBT drive fault, input over-voltage, and more.
Enclosure: IP30 for indoor and IP54 for outdoor installations, with forced-air or liquid-water cooling options.
Ambient Environment: Operates between -10 to 40°C, with storage temperatures from -40 to 85°C. Maximum humidity is 90% non-condensing, and altitude operation is up to 2200m with derating for higher altitudes.
