摘要： An electric semiconductor valve (V), for example a valve in a converter for conversion between alternating current and high-voltage direct current, comprises a plurality of semiconductor positions (TS1, TS2, ... TSN) with mutually series-connected semiconductor devices (T1, T2, ... TN). With the semiconductor valve energized by an alternating voltage substantially corresponding to the rated voltage thereof, the condition of an optional semiconductor position is checked by generating a test firing signal (FP) and supplying it to the firing channel (L, 1, TCU, 3) of the semiconductor position alone, whereupon an indicating signal (IP) delivered by the indicating channel (TCU, 2, D) of the semiconductor position is studied with respect to time.

摘要： A device (400) for sensing a binary signal (450) is provided. The device comprises means (410) for measuring a signal level of the signal, means (420) for determining whether the measured signal level is "low" or "high", means (430) for providing a variable input impedance, and means (440) for controlling the input impedance in response to the measured signal level. The variable input impedance may be provided by way of a transistor (T) and a resistor (R), and by controlling the duty ratio of the transistor using pulse width modulation. Preferably, the input impedance is controlled to be low for low signal levels and to be high for high signal levels, which results in a more reliable sensing of binary signals. The device may be used for detecting the state of contact transducers suffering from parasitic resistances caused by moist and/or polluted environments. Further, a method of sensing a binary signal is provided.

摘要： The invention concerns a method and first device (32) for transmitting data related to the control of a high voltage power transmission system as well as to a method and a second device (50) for receiving data related to such control. The first device provides (40) a frame of data including data symbols in a frame structure providing sections for data symbols containing measurement samples and field bus type of data, inserts (42) synchronization data into the frame in the form of control symbols distinctively separated from the data symbols and sends (44) the frame to the second device (50) in a point-to-point connection (34). The second device (50) receives (54) the frame, extracts (56) the synchronization data and processes (58) the frame after the extracting, for obtaining the data symbols. The synchronization data being inserted and extracted this way concerns synchronization of control activities performed by the second device.

摘要： The invention concerns a method and device for providing redundant control of a controllable current valve (46, 48) in a converter (16) of a power transmission system (10). The device includes a first converter control unit (34) sending a first valve control signal (CP1A, CP2A) and an associated first active/standby indicator (A_A), a second converter control unit (36) sending a second valve control signal (CP1B, CP2B) and an associated second active/standby indicator (A_B) and a valve control unit (32). An active/standby indicator indicates if a corresponding converter control unit is active or standby and only one indicator indicates an active unit at a given point in time. The valve control unit (32) receives the active/standby indicators and valve control signals, selects a valve control signal (CP1A, CP2A) to be applied if the corresponding active/standby indicator (A_A) indicates an active converter control unit and controls the current valve using the selected valve control signal.
