Design, Development and Implementation of a Hybrid Network with Smart Sensors and Power Line Communication for Monitoring of Underground Electricity Substation

摘要

The Smart Sensor Networks not only collect data, but also perform local processing, and may even operate in the system, and thereafter, if necessary, carry out the transmission. However, in some cases hybrid networks systems, that combine wireless with wired structures, may be more appropriate. The objective of this work is to develop a system that integrates a set of smart sensors and communication systems for use in an underground distribution power substation. The underground substation of the distribution system chosen belongs to the spot network located in Porto Alegre city, Brazil. Among all challenges of this work, establish the communication system installed inside the substation with the outside world, is without doubt the most complex, because, there are no commercial solutions for this problem. This paper presents the development of a hybrid smart system based on wireless sensor network combined with Power Line Communication. This system allows real time monitoring of the substation without the need to make any significant changes.
