What are the applications for HVDC in Brasil?

Three types of large networkThree typical problems to solve

1. Strong High Short Circuit Level2. Weak Electromechanical / Voltage Stability3. Meshed Power Flow Control

HVDC Solves all above problems


Not OnlyLong Distance Overhead Line

1000 km

Strong : Short Circuit Level

Weak : Stability

Meshed : Power Flow
