SYSTEM DESCRIPTION

Mitsubishi Electric Substation Division (SSD) is promoting a very important FACTS solution offering in our Fixed Series Capacitor. The application of series compensation allows transmission grid operators to recognize the many benefits of these systems in increased utilization of existing infrastructure. Series compensation systems counteract the natural impedance of transmission lines, thereby providing the following key advantages:

  • Increase real power capacity of existing lines
  • Increase voltage stability
  • Reduces angular deviation
  • Decrease in angular separation
  • DC Mitigation

When capacitors are applied in series with the line, it reduces the impedance, which results in lowering voltage drop, thus increasing the magnitude of power that flow through the transmission line. This becomes an economical FACTS solution that can greatly increase voltage load characteristics and transmission stability over distance
