摘要： A voltage balancing unit (330) for a symmetric monopole high voltage direct current (HVDC) transmission line (303) interconnecting two voltage source converters (VSCs) (301, 302), the transmission line comprising first arresters (321–324) having a first switching impulse protective level (SIPL), is provided. The voltage balancing unit comprises a pair of second arresters (331, 332) having a second SIPL which is less than the first SIPL, and switching means (333, 334) being arranged for temporarily connecting, in the event of a voltage unbalance on the transmission line, the first arresters between either pole (304, 305) and ground. The invention makes use of an understanding that a voltage unbalance on the transmission line may be removed by temporarily connecting second arresters, with a significantly lower SIPL than the first arresters, for limiting the pole voltage to a level close to the normal voltage. Further, a method of voltage balancing is provided. Voltage unbalances may arise as a consequence of lightning induced earth faults (311).

摘要： An oscillation in a power transmission system is detected by multiplying voltage or current f(t) by a signal from an oscillator oscillating at a frequency at which oscillations are expected. The result is sampled with a frequency which exceeds the oscillator's, and the latest samplings which correspond to one or more entire periods of the frequency of the oscillator are successively summated. The successive summations are multiplied by the oscillator signal, whereby a regulating signal is obtained. By analysis of the said summations, a diagnosis is made as to whether damping correction is needed, and if this is the case, said regulating signal is connected to a regulating device to disconnect this when it is no longer required. The invention can be used both to eliminate oscillations in cables for high voltage direct current transmission and to eliminate subsynchronous oscillations in alternating current networks provided with gas and steam turbines.

摘要： A breaker failure detection device for a direct current (DC) circuit breaker (200) is provided. The circuit breaker comprises a circuit breaking element (204) and a non-linear resistor, e.g., a surge arrester (205), connected in parallel. The breaker failure detection device comprises a current sensor (212, 213, 214, 215), for measuring a current commutating from the circuit breaking element (204), and a breaker failure detection unit (211). The breaker failure detection unit (211) is arranged for comparing the measured current to desired values and deciding that an internal commutation process of the circuit breaker (200) does not proceed as desired if the measured current deviates from the desired values. The present invention makes use of an understanding that an improved detection of breaker failures may be achieved by monitoring the internal commutation process of the circuit breaker. Further, a method of breaker failure detection is provided.
