Wireless sensor network for electrical secondary substations

The automation of devices in the substations has thus become a priority, in order to prevent such accidents. The IEC 61850 is a new automation protocol, designed for the purpose of establishing a common standard for all substations, one that all manufacturers of all different devices must comply with. In the present day, not all distribution substations are automatized, as is the case with secondary substation, due to the fact that the automation costs are higher than the cost of the substation itself. This paper advocates the projection, implementation and evaluation of a wireless sensor network (WSN) acquiring of noncritical data on distribution substations. The sensor network is constituted by wireless modules, using ZigBee technology, integrating the communication model based on IEC 61850.
