Distribution of the electricitygrid of a tiny house community

Powerline communication

More Info


This thesis will discuss the design, simulations and measurements of a powerline communication system that utilizes FSK modulation in order to transfer information from a transmitter to a receiver at a baud rate of 1kbps, in order to reach the requirement of having an effective data rate of at least 6bps. This system is designed specifically to be implemented in the smart DC grid of a sustainable "tiny house" community. This thesis investigates the different subsystems needed to create this communication system and compares different methods and implementations. This research led to the conclusion that the communication system was successfully build and could reliably reach a baud rate of 700bps, which appeared to be more than enough to reach a data rate of 6bps. The system also showed to be resistant to 'high levels' of noise on the communication channel as defined in the CELENEC standard. Furthermore, in order to decrease the bit error rate further, additional bit error detection and correction has been implemented using microcontrollers. This led to a robust and nearly error free communication system over a tested powerline of 50 meters long.
