Data management of on-line partial discharge monitoring using wireless sensor nodes integrated with a multi-agent system
On-line partial discharge monitoring has been the subject of significant research in previous years but little work has been carried out with regard to the management of on-site data. To date, on-line partial discharge monitoring within a substation has only been concerned with single plant items, so the data management problem has been minimal. As the age of plant equipment increases, so does the need for condition monitoring to ensure maximum lifespan. This paper presents an approach to the management of partial discharge data through the use of embedded monitoring techniques running on wireless sensor nodes. This method is illustrated by a case study on partial discharge monitoring data from an ageing HVDC reactor
Integrating an agent-based wireless sensor network within an existing multi-agent condition monitoring system
The use of wireless sensor networks for condition monitoring is gaining ground across all sectors of industry, and while their use for power engineering applications has yet been limited, they represent a viable platform for next-generation substation condition monitoring systems. For engineers to fully benefit from this new approach to condition monitoring, new sensor data must be incorporated into a single integrated system. This paper proposes the integration of an agent-based wireless sensor network with an existing agent-based condition monitoring system. It demonstrates that multi-agent systems can be extended down to the sensor level while considering the reduced energy availability of low-power embedded devices. A novel agent-based approach to data translation is presented, which is demonstrated through two case studies: a lab-based temperature and vibration monitoring system, and a proposal to integrate a wireless sensor network to an existing technology demonstrator deployed in a substation in the UK
Wireless Sensor Network Virtualization: A Survey
Wireless Sensor Networks (WSNs) are the key components of the emerging
Internet-of-Things (IoT) paradigm. They are now ubiquitous and used in a
plurality of application domains. WSNs are still domain specific and usually
deployed to support a specific application. However, as WSN nodes are becoming
more and more powerful, it is getting more and more pertinent to research how
multiple applications could share a very same WSN infrastructure.
Virtualization is a technology that can potentially enable this sharing. This
paper is a survey on WSN virtualization. It provides a comprehensive review of
the state-of-the-art and an in-depth discussion of the research issues. We
introduce the basics of WSN virtualization and motivate its pertinence with
carefully selected scenarios. Existing works are presented in detail and
critically evaluated using a set of requirements derived from the scenarios.
The pertinent research projects are also reviewed. Several research issues are
also discussed with hints on how they could be tackled.Comment: Accepted for publication on 3rd March 2015 in forthcoming issue of
