    Abstract: A power transmission system (100) is disclosed, comprising at least a first Alternating Current (AC) region (10) and a second AC region (20) interconnected by at least one AC power transmission line (31, 32), a DC link (40) interconnecting the first AC region (10) and the second AC region (20), and at least a first converter station (50) configured to control flow of power therethrough between the DC link (40) and the first AC region (10). The power transmission system (100) comprises a control unit (70) configured to control flow of power through the first converter station (50) between the DC link (40) and the first AC region (10) by generating a control signal based on phasor measurement entity (PME) measurements in or from the first AC region (10) and in or from the second AC region (20), respectively, in particular based on a comparison or difference between a second AC phase angle, determined based on one or more AC phasors measured in the second AC region (20), and a first AC phase angle, determined based on one or more AC phasors measured in the first AC region (10).

    Abstract: In a method, computer program and system for determining an operational limit of a power transmission line, time-stamped current phasor information and voltage phasor information for a first end and a second end of the line are determined, an ohmic resistance of the line is computed from the phasor information, and an average line temperature is computed from the ohmic resistance. This allows to determine the average line temperature without dedicated temperature sensors. The average line temperature represents the actual average temperature and is largely independent of assumptions regarding line parameters.
