Method for establishing a wireless communication system in a high-voltage power converter station and a high-voltage power converter station

A method for establishing a wireless communication system in a high-voltage power converter station including a plurality of power devices, wherein the wireless communication system includes a plurality of wireless communication devices, some of which being associated with a power device such that a power device and a wireless communication device together form a wireless power electronic module, and at least one wireless networking device for providing a communication interface between the plurality of wireless communication devices and a controller configured to control said power devices, the method comprising:

• obtaining, at the controller, an indication of signal quality for each one of a plurality of first channels, wherein a first channel corresponds to a communication path between one of said at least one wireless networking device and a wireless communication device of the plurality of wireless communication devices using one of a plurality of radio beam directions;
• obtaining, at the controller, an indication of signal quality for each one of a plurality of second channels, wherein a second channel corresponds to a communication path between a wireless communication device and a wireless power electronic module of the plurality of wireless power electronic modules using one of a plurality of radio beam directions;
• and
• determining, by the controller, for every wireless power electronic module, at least one communication path from the controller to the wireless power electronic module based on the indications of signal quality obtained for the plurality of first channels and the plurality of second channels, wherein the determined communication path provides a signal quality above a threshold.
