Definitions

  • the invention relates to a method for operating a plurality of thyristor controllers connected in parallel by means of an oscillation packet control, the thyristor controllers being switched on one after the other with a delay time which is less than the cycle time.
  • Such a method and a device for performing the method is known from DE-OS 28 55 332.
  • vibration packet control a certain number of sinusoidal vibrations are passed through the thyristor controller, which together form the vibration packet. After a predetermined pause time, the next vibration packet is fed to the load circuit. The power delivered to the consumer is controlled by changing the width of the vibration package.
  • the known method has the particular disadvantage that all consumers can only be operated at the same current and their switch-on times must be the same.
  • the invention is therefore based on the object of making available a method for operating a plurality of thyristor controllers connected in parallel by means of an oscillation packet control, the consumers connected to the thyristor controllers also being able to be operated with different currents and possibly also very different switch-on times.
  • each thyristor controller is set as a function of the switch-on time and the current amplitude of all thyristor controllers in such a way that the effective value of the mains current is minimized within one clock period.
  • This method is essentially carried out in such a way that for each thyristor actuator its respective switch-on time and the current amplitude are determined and for each thyristor actuator a delay time is determined which enables operation without a disturbing flicker occurring. This is the case if, given the current amplitudes and switch-on times of the individual thyristors, the delay times are determined in such a way that the effective value in the network reaches a minimum.
  • the thyristor controller 1, 2 and 3 consist, as usual, of two antiparallel connected thyristors and an associated control unit with which u. a. the control currents of the two thyristors can be generated.
  • Loads 4, 5 and 6 are connected in series with the thyristor controllers 1, 2 and 3, with the network inputs on the lines or connections 7 and 8.
  • a central, intelligent controller 9 is also provided, which are connected to the thyristor units 1, 2 and 3 via a data line 10. Both data of the thyristor controller, such as. B. control angle and the current, are queried and data are sent to the control units of the thyristor controller, in particular to adjust power in the load as a function of predetermined parameters, which will be explained in more detail.
  • Fig. 2 the currents in the thyristor branches I01, I02 I03 and the mains current I L are shown depending on the time.
  • the cycle time T0 ie the time that lies between the use of electricity by two successive oscillation packets
  • T S1 , T S2 and T S3 a current flows in the respective thyristor controller, the current profile during these time intervals being shown as a rectangular pulse, which is composed of a large number of oscillations to form an oscillation packet.
  • the individual thyristor controllers are each switched on offset by the constant delay time t v , so that only one thyristor controller carries current and thus loads the network.
  • This mode of operation assumes that the delay time t v is equal to T O / n , where n indicates the number of thyristor controllers. Only in this case is it guaranteed that only one thyristor controller is connected to the network. Since, in the known procedure, the current amplitude is the same for all thyristor controllers and the network is only loaded by one thyristor controller, there is a current profile as the mains current that does not cause network dips in such a way that other consumers that contain light sources and also on the same Network, flicker appear.
  • the setting of the delay times is computer-protected and can be carried out by the person skilled in the art without further ado if the teaching is given to him according to the method according to the invention that the delay time of each thyristor controller is set as a function of the switch-on time and the current amplitude of all thyristor controllers in such a way that the RMS value of the mains current is minimized.
  • the minimum effective value can also be measured in the mains circuit.
