A computerized platform for monitoring the operation of an electric power distribution grid which includes in one form an accessory device operatively coupled with or comprised in an electronic protection relay of said electric power distribution grid, wherein said accessory device is configured to gather grid data and to transmit said grid data through the Internet; a publishing computerized unit capable of communicating with said accessory device through the Internet, said publishing computerized unit being configured to interact with said accessory device to acquire and store said grid data; an interface computerized unit capable of communicating with said accessory device and said publishing computerized unit through the Internet, said interface computerized unit being configured to provide interface services to manage the interaction of said accessory device with said publishing computerized unit.

Computerised platform for monitoring the operation of an electric power distribution grid

A communication network for a low-voltage switchboard comprising three types of communication bus. The first communication bus is designed to provide a first communication channel with at least one electronic protection device. A second communication bus is designed to provide a second communication channel with said electronic protection device. At least one third communication bus () is designed to provide a third communication channel between said at least one protection and control unit and one or more additional electronic modules (A,B,C,E,F). The second communication bus is associated with a second, higher user access level than the first user access level associated with said first communication bus.

Communication network for a low voltage electric switchboard

An electric power distribution switchboard () in which one or more functional units are equipped with a switching device compartment () that integrates primary and secondary functions. Within the switching device compartment () are included, together with the switching device (), the current and voltage sensors (), the position sensors for interlocking, a human machine interface (HMI) and an Intelligent Electronic Device (IED) () and the related local configuration point () to configure the IED (). The IED () realizes functional unit supervision, control, protection, communication and monitoring and acts as a concentrating point of functional unit information and decisions. The switchboard () of the invention further comprises power supply section, an I/O section and a communication system.

Medium voltage integrated switchgear

A device for powering one or more electric/electronic devices operatively associated with a low-voltage circuit breaker takes energy from a power supply line. An electronic regulator receives the energy collected as an input and delivering as an output to the electric/electronic device a power supply voltage (Vout) having a value within a preset range with respect to a reference voltage (VR). The electronic regulator includes an energy storage device chargeable by the energy collected, at the terminals of which a voltage (VCL) is established that is indicative of the power supply voltage (Vout) delivered to the electric/electronic device. A circuit enables/disables the charging of the storage device, and a feedback circuit receives a signal indicative of the voltage (VCL) at the terminals of the storage device and sends a signal to the enabling/disabling circuit to trigger the disabling or enabling of the charging process in order to keep the value of the voltage at the terminals of the storage device within a preset range. The feedback circuit enables the charging phases so as to power the storage device continuously up until the value of the voltage at their terminals comes within the preset range.
