Abstract: An intelligent electrical power network control and/or protection device comprises at least one power supply connection for connecting the device to a main power source and an auxiliary power source and at least one unit configured to monitor main power, the unit being configured to activate a signal indicating lack of main power in response to lack of main power. The device further comprises at least one unit configured to provide a state control operation for changing an operating state of at least one unit of the device or an operating state of at least one unit to be connected to the device from an operative mode t a power saving mode in response to the activated signal indicating the detected lack of main power.

Abstract: A distribution controller is disclosed for controlling a distribution of electrical power in an assigned power distribution region. The controller is adapted to be communicatively connected to process or secondary devices (IEDs, RTUs) which in turn interact with primary devices of the assigned region. The controller includes a processing module executing algorithmic, logical or functional modules or client applications. The latter implement application function algorithms that calculate, based on process data from process devices connected to the controller, values of a power distribution quantity such as voltage, current, power flow, load, or a phasor quantity of the assigned region. The controller further includes, for the purpose of data exchange with the process devices communicatively connected to the controller, data servers. The controller is adapted for writing the output or results of the functional module, i.e.

Abstract: The object of the invention is an automation data communications network (3-1, 4-1) comprising a control and data acquisition device (3-2, 4-2), said device supporting a protocol for controlling communications within said network (3-1, 4-1), and one or more IEDs (4-8 . . . 4-16), said device supporting a protocol for controlling communications within said network (3-1, 4-1) and including a switch (4-8a) with at least two ports arranged in a functional connection with the device. The invention is characterized in that an element (4-6) with at least two ports is arranged in a functional connection with the control and data acquisition device (3-2, 4-2) and that a first loop is arranged between the IEDs (4-8 . . . 4-16) and a second loop is arranged between the IEDs (4-8 . . . 4-16) and the control and data acquisition device (3-2, 4-2).
