Healthy pole control strategy

Converter stations coordination principles

Description

Healthy pole control strategy objective is to achieve a fast power rampup, followed by a fast power ramp-down, while respecting following constraints:

  • physical limits of converters
  • power balancing in healthy pole (condition for DC voltage stability)

Status

Available license

TRL SCALE

Advantages

  • To take benefit of having a bipolar scheme (or double monopole), and use healthy pole to enhance AC system stability during faulty pole transient.

Applications

  • Multi-terminal DC grid in bipolar (or double monopole) configuration.
  • Especially relevant in case of non-selective protection strategies, or protection stratégies that lead to power transfer temporary interruption.

Deliverables
