SAF High Voltage Compensation System

High Voltage Compensation System Used for Submerged Arc Furnace

I. Overview
Compensation equipment is a key component in metallurgical power supply systems, used to improve power factor, stabilize voltage, filter harmonics, reduce line losses, and ensure stable operation of impact loads such as EAFs and refining furnaces. Based on voltage level, compensation principle, and functional characteristics, they are mainly classified into the following types:

1. According to the voltage level: High Voltage Compensation Equipment and Low Voltage Compensation Equipment
2. According to the function: Reactive Power Compensation Device, Harmonic Mitigation Device and Integrated Compensation Device

II. High Voltage Compensation Equipment

High voltage compensation equipment is mainly used in 6-35kV power supply systems, commonly found in substation buses for impact loads such as large EAFs, SAFs, and rolling mills .

1. High Voltage Shunt Capacitor Bank

Parameter Range
Rated Voltage 6kV, 10kV, 35kV

  • ZnO surge arrester

  • Post insulator

  • Earthing switch

2. Static Var Compensator - SVC
SVC uses thyristor-controlled reactors (TCR) combined with thyristor-switched capacitors (TSC) or fixed capacitor banks (FC) to achieve dynamic reactive power compensation, with response time of 10-20ms, suitable for rapidly changing loads such as EAFs .

Parameter Range
Rated Voltage 6-35 kV

Main Components of SVC :

  • Digital control cabinet

  • TCR thyristor valve group

  • TSC thyristor valve group

  • Main reactor

  • Water cooling system

  • Triggering system

  • Fixed capacitor bank/filter

3. Static Var Generator - SVG / STATCOM

SVG/STATCOM uses IGBT inverter technology with voltage source converter (VSC) as the core, can quickly and continuously provide capacitive or inductive reactive power, with response time <5ms, offering advantages such as good dynamic performance, continuous output, and small footprint.

Parameter Specification
