Abstract
A land electrode for a high voltage direct current transmission system including a converter station with a grounding point. The land electrode is connected to the grounding point and includes a plurality of electrode sections. A line electrode includes a part interconnecting two electrode sections. The part of the line electrode exhibits a line resistance. Each electrode section includes at least one electrode element.
Claims10
A land electrode for a high voltage direct current transmission system having a converter station with grounding point, the land electrode being connected to the grounding point and comprising:
- a plurality of electrode sections, each electrode section comprising at least one electrode element;
- and
- a line electrode, wherein a part of the line electrode interconnecting two electrode sections exhibits a line resistance, and wherein each electrode section comprises a tuning resistor configured to connect the electrode section to the line electrode.
A method for grounding a high voltage direct current transmission system comprising a plurality of electrode sections each including at least one electrode element, the method comprising:
- providing in each electrode section a tuning resistor, connecting the electrode sections to a line electrode so that a part of the line electrode interconnecting two electrode sections exhibits a line resistance, and
- tuning the tuning resistor to equal current flow for each section.
