Such a power supply system is shown in FIG. A wave generator 10 with an excitation winding 11 and one Armature winding 12, which is driven by a propeller shaft 13, feeds an uncontrolled rectifier 14. The rectifier is a net-commutated converter 15 neohge achalt et, which is in a On-board power supply 16 stores parallel s * a output of the converter 15 is also a Π ^ ιιιΊΐιι sei — auliiae 17 as an on-board generator, the A Biesel unit 19 is coupled via a switchable coupling 18 Sn iat, and which runs as a phase shifter when the ship is free at sea and in yeast operation to supply the on-board network a 16 is used.

The invention first proposes that the line-commutated converter be activated in a manner known per se and that the ignition angle t \ ir of each controllable electric valve depends on the voltage driving its commutation current in such a way that ignition then takes place, if this voltage falls below a limit value formed by a specified reference voltage. Controllable electrical valves within the meaning of this invention are

All embodiment of the invention is therefore intended to increase the security against low-frequency power converters provided that the ignition angle for each one controllable electrical Valve is limited to an angle of over 90 degrees. This happens in a particularly favorable manner in such a way that the The ignition angle for a single controllable electric valve is limited to angle values of over 90 Orad.

The measures according to the invention but determination of the ignition angle and their effects are shown in figures 2a, 2b, 2c.

FIG. 2b shows a customary mains-commutated converter built up on one controllable electric valves u ^ _f U ₂ * V / p V ₂ , W ₁ , W ₂ , to which a direct current is supplied by the control-controlled rectifier and the voltage U is supplied to the board "under the Fhaaenspsnnung u, v, w emits alternating current.

The course of the spinning u, ν, ι forming a three-phase system as a function of the side t bsw · tob »angle t is shown in FIG. 2b. In the case shown, the electrical valves v ^, U ₂ are initially healthy during honing operation. In the usual cyclical sequence of the electric valve, ν ^ suf W ^ ₉ because U ₂ suf V ₂ * must be commutated from w ^ to u ^. The Ätindwinkel «* _u1 is for the skin of the electric valve U ₁ counting from that angle * jt to su where the voltage u becomes positive and the two voltages v, w become greater. From this angle sn it is finally possible to commute to U ₁ su. The voltage that drives the Xoaautierungsstroa during the commutation of W ^ suf U ₁ is the differential voltage u - w between the voltages u and w.

The course of the differential voltage u - w as a function of the ignition angle _u1 is shown in FIG. 2o, the voltage aafietab deviating from that of FIG. 2b. The profile of a similar sawtooth-shaped reference voltage U _{x is also} shown, which according to the invention has the frequency of the mutating current

driving differential voltage u »w is periodic puncture of time t and has no positive values for ignition angles ^ ^ from 0 to 90 degrees. The intersection of the curve of the differential voltage u - w with the reference voltage u as the limit value determines the ignition angle ioc *. Circuits which emit a voltage pulse to ignite an electrical valve when the value falls below the threshold value are known. If the differential voltage u - w sinks, for example if there is an overload in the on-board network, and has the curve shown by dash-dotted lines in F.gur 2c, then the ignition of the electric valve u ^ already takes place at the smaller ignition angle o ^ ₂ * prevents a reduction in the voltage-time area required for commutation.

The reference voltage u in the example in FIG. 2c is therefore tooth-shaped rooted, well such a tension curve in known This can also be achieved with simple electrical means. It however, the reference voltage can be advantageous for achieving an even greater reduction in the ignition angle in the fault skin give any other, for example a sinusoidal or rectangular course au.

A special design of the constructed and controlled according to the invention The converter has the tusät «lent goal of a possible Division of the converter into spatially separate, similar components, which can be beneficial on board ships This embodiment is based on the fact that the tension in each electrical valve of the converter of the voltage

if there is undisturbed commutation of the converter, too To ensure short-term, temporary faults such as intermittent short circuits, the invention proposes that when the voltage at the input of the converter collapses by simultaneously burning both electrical valves of one phase of the converter, for example after a short circuit in the on-board network »the ignitions of all controllable electrical valves are switched off and only then released again, if in the sense of the logical function "AND" both a given The minimum time has elapsed how the AC voltage at the output of the converter has again approximately reached its nominal value »

A measure to avoid overflow of the behind the uncontrolled rectifier current flowing and thus to protect the line-commutated converter in the event of a fault according to the invention in that the direct current flowing between the uncontrolled rectifier and the converter is exceeded its nominal value is traced back to the excitation of the wave generator in the sense of its weakening via a threshold value image is.
