Abstract

The present invention relates to a communication network in a power converter cabinet (1). The power converter cabinet (1) comprises at least a control unit (5; 7a, 7b) and at least a power switch (6a-d), a sensor (8-10) or an actuator, and wherein the first communication point (2) is connected to the at least a control unit (5; 7a, 7b) inside the power converter cabinet (1), and the second communication point (3a-d) is connected to the at least a power switch (6a-d), a sensor (8-10) or an actuator inside the power converter cabinet (1). The communication network comprises: a first communication point (2), provided with a first antenna configured to wirelessly transmit / receive in the mm-wave frequency band, with an opening angle of between 20 and 180 degrees; and a second communication point (3a-d), provided with a second antenna configured to receive / transmit wirelessly in the mm-wave frequency band, with an opening angle of between 20 and 180 degrees; wherein the first and second communication points are configured to set up a communication link with multiple propagation paths, to send data between different active devices and / or components inside the power converter cabinet (1).The present invention also relates to a power converter cabinet and a method for communication within a power converter cabinet.

Description

Technical field [0001] The invention relates to a communication network in a power converter cabinet. The invention also relates to a power converter cabinet and a method for communication in the power converter cabinet. Background technique [0002] Communication is a necessary and integrated part of the power converter. This type of communication needs to be stable, reliable, and have a relatively short delay. The control unit needs to communicate with several, even hundreds or more components / batteries / power modules. The communication unit can be placed at different potentials (above several kilovolts), requiring electrical insulation between the transmitter and receiver. [0003] The traditional method to solve this kind of communication problem is to use optical fiber, which can provide short enough delay, sufficient data rate and electrical insulation. The problem with these optical components is that their performance degrades over time. In addition, they require a lot ...
