Abstract: A method in a three-terminal differential protection includes measuring a terminal phase current (IT1(y), IT2(y), IT3(y)) at each terminal (T1, T2, T3) of a protected zone of the differential protection in each phase (L1, L2, L3) to be protected, and determining a bias current (Ib(y)) of the phase on the basis of the terminal phase currents (IT1(y), IT2(y), IT3(y)). The bias current determination includes subtracting phasor values of the terminal phase currents of two terminals from the phasor value of the terminal phase current of one terminal. The terminal phase current, which is a minuend in the phasor difference computation, is selected on the basis of the phase angles or amplitudes of the terminal phase currents.

Abstract: A system that measures a high electric voltage on an electrical transmission line has an electro optical voltage transducer sensor connected between the electrical transmission line and ground for providing in response to the measured high electric voltage a Sin optical intensity signal and a Cos optical intensity signal. The system also has a signal processor that operates in a first state to digitally process samples of the Sin and said Cos optical intensity signals. The process samples are used to provide a representation of the high electric voltage on the transmission line. The representation can be used for one or more of metering, relaying and transient capture.

Abstract: In one aspect of the teachings herein, a self-commutated current source converter is operated in a manner that compensates for the reactive power consumption and/or harmonics generation of a line-commutated current source converter used in the transfer of electrical power between an AC power system and a DC power system. In this regard, the line-commutated current source converter is operated as a first converter in a hybrid converter apparatus and the self-commutated current source converter is operated as a second converter in the hybrid arrangement. According to one example, the first and second converters are stacked, such that each shares a portion of the DC voltage on the DC side of the hybrid converter apparatus, while in another example, the second converter is not used for power conversion and instead is used solely for compensation with respect to the first converter.

Abstract: A method for controlling a modular converter with a plurality of converter modules includes: selecting possible future switching sequences of the converter based on an actual converter switching state; predicting a future current trajectory for each switching sequence based on actual internal currents and on actual internal voltages; and determining candidate sequences from the switching sequences, wherein a candidate sequence is a switching sequence with a current trajectory that respects predefined bounds with respect to a reference current or, when a predefined bound is violated, moves the current closer to such a predefined bound. The method includes predicting future module voltages for each candidate sequence; evaluating a cost function for each candidate sequence; and selecting the next converter switching state as a first converter switching state of a candidate sequence with minimal costs.
