Definitions

  • the invention relates to a method for parallel control of step transformers equipped with tap changers according to the preamble of the claim.
  • step transformers to be connected in parallel are identical in terms of their voltage steps and number of steps, the control process is relatively simple; all that is important is that all tap changers are at the same voltage level at all times, otherwise there will be a compensating current between the secondary windings. This is already known from DE 11 39 918. From AT 126 517 it is also known to provide auxiliary changeover switches that have the same number of contacts as the tap changer.
  • the known control methods can essentially be divided into two groups: On the one hand, for example from DE 11 56 880, the so-called “master-slave” methods are known, ie a synchronous control is implemented in which a step transformer as "Master” is selected, which the other step transformers "follow".
  • the second option is real parallel control, with all step transformers working in equal operation.
  • a corresponding control device is known from the SIEMENS magazine 1956, volume 2, pages 100 ff .: "The parallel control of transformers with tap changers", in which a control device is assigned to each tap changer; a similar device is disclosed in DE 30 32 874.
  • the voltage regulators measure the respective voltage by means of a voltage converter; the downstream parallel control units are required to ensure that a different step position of the step transformers connected in parallel also leads to regulation if the sum of the voltages corresponds to the nominal voltage of the system.
  • the parallel control units generate a control variable that is proportional to the circulating reactive current component of their own step transformer and acts on the voltage regulator.
  • the object of the invention is to use a new method for parallel control without cross connections between the control and regulating devices assigned to each step transformer and thus to create the possibility of universal wiring of the system for any number of step transformers and busbars, which can also be added subsequently expandable with little effort.
  • the circuit complexity is to be further reduced by the fact that the novel method should allow only one parallel control unit to be used.
  • the new method requires a preferably microprocessor-controlled parallel control device which is connected in series to the individual voltage regulators, which, as is known from the prior art, are each associated with each step transformer.
  • the serial data lines reduce the likelihood of wiring and other errors.
  • a parallel control unit P is given the current step transformer configuration, i.e. the information about which step transformers work in parallel on which busbars.
  • step transformers T1 ... T6 can be linked to the two busbars in all conceivable switching combinations.
  • Each step transformer T1 ... T6 is assigned a voltage regulator R1 ... R6, which measures the amplitudes of voltage and current and the phase angle on each step transformer in a manner known per se and successively transmits these values to a parallel control device P via serial data lines.
  • the disturbance variable and the partial load current are in turn transmitted to the individual voltage regulators R1 ... R6 via the serial data lines.
  • the line voltage drop can thus be compensated for in a manner known per se.
  • the serial data line can also be designed as a ring line (e.g. RS485) instead of as a point-to-point connection as described.
