    Abstract: The present invention is concerned with a method of distance protection of parallel transmission lines applicable both to series compensated and uncompensated electric power lines, using a distance relay. The method is characterized in that a pair of a flags (ff1, ff2) are calculated for indication faulted and healthy circuits in parallel lines and in the same time a flag (lnternal_Fault) for indication internal or external fault in parallel lines is calculated in independent way. Next gathering all calculated flags (ff1, ff2, lnternal_Fault) an analyze of the value of these flags are performed and depending on the values of flags (ff1, ff2, lnternal_Fault) and on their reciprocal relationship, a trip permission signal from the protection relay (4) is released and sent to the alarms devices or to the line breakers, or a block signal from the protection relay (4) is generated and sent to the users in order to protect parallel lines before damage.

    Abstract: In the field of electrical networks, and in particular distribution networks that include distributed voltage sources such as distributed generators, there is a need to safely manage the operation of the networks. A circuit interruption apparatus (10), for an electrical network (18), comprises a circuit interruption device that is operatively connectable at a source side (30) to a source of the electrical network (18) and at a back side (32) to a load of an electrical network (18). The circuit interruption device when closed permits current to flow between the source side (30) and the back side (32), and the circuit interruption device when open inhibits current from flowing between the source side (30) and the back side (32). The current interruption device is configured to open when a current (I) flowing therethrough meets or exceeds a fault current threshold. The circuit interruption apparatus (10) also includes a fault current level determination unit that is configured to determine a predicted fault current level (I PFI ) as a function of measured current and voltage values (I, U) at the circuit interruption device before and after a variation in the current and voltage values (I, U) at the circuit interruption device that result from a change of load at the back side (32) of the circuit interruption device.

    Abstract: A protection system (200) for high voltage direct current, HVDC, transmission lines is provided. The protection system comprises a direct current, DC, bus (201), means (202) for connecting an HVDC transmission line to the bus, at least one DC circuit breaker (203, 204) arranged for disconnecting the transmission line from the bus upon reception of a trip signal, current (211) and voltage sensors (212), an inductor (213) arranged such that the current through the transmission line passes the inductor, and a fault detection unit (220). The fault detection unit is arranged for assessing, on the basis of current and/or voltage measurements, whether a fault exists on the transmission line, and sending, if a fault is detected on the transmission line, a trip signal to the circuit breaker. The additional inductance limits the rise in fault current and facilitates a selective fault detection. Further, a method of fault protection for an HVDC transmission line is provided.
