Smart secondary substation management device

The aim of this paper is to describe a new device that will be installed into the smart secondary substations. It allows the full management of the substation and integrates control, protection, measurement and communication functionalities, on both sides, low voltage and medium voltage side. This device is integrated into a global architecture of automation network as an additional element and it communicates upstream with central systems and downstream with Smart meters installed in low voltage network that is supplied by the substation, managing their information and allowing remote operation on them. The device has been designed with a modular and scalable feature, in this way it provides a standard solution for different topologies of secondary substations.
