Wireless integrated network sensors (WINS) implementation in substation automation (SA)

Summary form only given. This paper present a novel approach to the SA communication that is tailored to this level of resolution of sensors using wireless integrated network sensors (WINS). We refer to the substation as a sensor field (SF) which includes the sensor nodes (SN) scattering inside as the end units for the entire system. The SF is communicating with the user/task manager node through a sink, which is responsible for an event area (EA), using multiple wireless communication paths. This paper present a technical model for the implementation technique of the WINS to the SA, as well as some economical aspects. MV systems was used in the examples and simulations that support the model and the whole approach that might raise the level of SA reliability towards fault tolerance. The authors believe that the WINS will became a serious player also in the flexible AC transmission systems (FACTS) and in the distributed energy sources (DER) applications due to the topology of those systems and the interconnections common protocols developed these days.
