摘要： A method and apparatus are described for operating a high voltage d.c. (HVDC) transmission line system connecting two a.c. transmission line systems during normal operation and during malfunction in either the rectifier station or the inverter station of the HVDC system.When a malfunction exists in one station of a HVDC transmission line, such as a rectifier station, then the regular thyristor firings are disabled and a bypass circuit, preferrably one or several bridge paths of a converter, are fired. As soon as a corresponding change in the current or voltage occurs at the d.c. voltage connections of the other station, this station assumes rectifier operation during which the HVDC transmission line is utilized as a reactive load to stabilize the other system. Once the malfunction has ceased to exist, operation is first resumed in the first station by extinguishing the bypass thyristors and subsequently resumed also in the other station. This procedure permits stable normal operation in both stations, or bypass operation without using remote control signals during which the HVDC transmission line can be rapidly controlled to stabilize the systems.

摘要： The input signal corresponding to the respective frequency or power variation is supplied both to the inputs of the discrete filters and to angle measuring devices assigned to them, of which only the tuned filter in conjunction with its angle measuring device actuates a switch which sends the filter output via angle rotating and matching elements to a MAX selector element, from which the supplementary damping signal for the excitation is tapped. For low oscillation frequencies a low-press filter is provided which, via mean value formers and time delay multivibrator stages, permits a regulator signal to become operative for the excitation, delayed or undelayed, when certain limit values are exceeded.

摘要： A six-pulse rectifier circuit includes a rectifier bridge, with six valves, arranged in the secondary circuit of a three phase transformer having an increased internal resistance and shunted by a load resistor arrangement for sensing the actual value voltage for use in a fast control device with the resistance of the load resistor arrangement matched to the increased internal resistance of the transformer, so that at least three but no more than four of the six valves are always commutating.
