Substation remote control equipment for distribution networks

STCE-D is an integrated system for peripheral control, the compact solution for remote control and monitoring of secondary distribution power stations. Made for both indoor (masonry secondary substations) and outdoor (pole) installation, it has been specifically designed to manage a large number of peripheral stations, while still providing best performances.

As the whole STCE family, it offers a wide range of features to meet the remote control needs of electrical distribution secondary networks. STCE-D complies with Enel, Italian distribution operator, technical specifications for the new UP equipment of the MV network. In particular, it not only conforms to the DX1215 rev. 7 standard, but it extends its functionalities supporting the programmable logic according to IEC 61131-3 and implementing the IEC 61850 protocol (server and GOOSE). IEC 61850 allows the management of several innovative functions required by Smart Grids, such as the Selective Logic and the meshed management with petal reclosure on different feeder of the same MV half-busbar in a Primary Substation.

Among the main advantages, there are the QoS enhancement, operating costs reduction, network availability increase granting availability to final users, maintenance costs optimization thanks to timely intervention in emergencies.
