Digital protection and control device and method thereof
First Claim
1. A digital protection and control device for a power distribution network, comprising:
- a control unit including a microprocessor;
a human-machine interface for allowing a user to access said control unit, said microprocessor exchanging data/information with said human-machine interface; and
a user authentication mechanism for regulating the access of the user to said control unit,wherein said user authentication mechanism comprises an electronic authentication device associable to said human-machine interface, andwherein said electronic authentication device is configured for;
storing first predefined data/information comprising at least a user identification code for establishing the identity of a user and a user access code for establishing the access mode of a user in said control unit;
storing second predefined data/information for configuring one or more functions of said digital protection and control device in said electronic authentication device; and
communicating with said control unit, when said electronic authentication device is associated with said human-machine interface, at least one of a portion of said first predefined data/information and a portion of said second predefined data/information being downloaded into said control unit when said electronic authentication device communicates with said control unit.

Abstract
The present invention provides a digital protection and control (P & C) device for a power distribution network, which comprises a control unit and human-machine interface (HMI) for allowing a user access to the control unit. The control unit comprises a microprocessor that exchanges data information with the HMI. The digital P & C device, according to the present invention, further comprises a user authentication mechanism for regulating the access of a user to the control unit. This user authentication mechanism comprises an electronic authentication device, associable with the mentioned HMI, which stores first predefined data/information. This first predefined data/information comprises at least a user identification code, for establishing the identity of a user; and a user access code, for establishing the access mode of the user to the control unit. In addition, the electronic authentication device is able to communicate with the control unit, when it is associated with the HMI of the digital P & C device.
