Abstract
The use of wireless communication technologies in the industry offer several
advantages. One advantage is the ability to deploy sensors where they previously could not
easily be deployed, for instance on parts that rotate. To use wireless communication in industrial
control loops, demands on reliability and latency requirements has to be met. This in an
environment that may be harsh for radio communication. This work presents a reliable, low
latency wireless communication system. The system is used in a wireless thyristor control loop
in a hydro power plant generator. The wireless communication is based on Bluetooth radio
modules. The work shows a latency analysis together with empirical hardware based latency
and packet error rate measurements. The background noise of a hydro power plant station is
also investigated. The average latency between the Bluetooth modules for the proposed system
is 5.09 ms. The packet error rate is 0.00288 for the wireless low latency control system deployed
in a hydro power plant.
