For the control of an electric power transmission network, where local protection functions are implemented by a plurality of local protection devices ( 3,3 a, 3 b, 3 b' ,3 c) located at a plurality of locations throughout the network, the following steps are executed measuring phasor data for voltages and currents at a plurality of locations (A,B) of the network, transmitting said phasor data to a central processing device ( 2 ), emulating, in the central processing device ( 2 ), protection functions that are implemented in the local protection devices ( 3,3 a, 3 b, 3 b' ,3 c), and executing, in accordance with a given redundancy strategy, control commands that are issued redundantly by the local protection devices ( 3,3 a, 3 b, 3 b', 3 c) and by the central processing device ( 2 ). In a preferred variant of the invention, values of predetermined parameters that are used in the protection function, in particular protection threshold values, are adapted to measured values. |
