Definitions

  • the invention relates to a method for optimizing the efficiency in ships with bow and stern propellers, in particular in ferry boats, the speed of the front propeller being lower than the speed of the rear propeller.
  • the invention also relates to the associated arrangement for adjusting the speed of the bow propeller in such ships with a symmetrical propeller arrangement and in each case associated separate drives.
  • Modern ferries can have a bow propeller and a stern propeller, both of which are driven by separate drives. Such an arrangement prevents the ship from being turned to reverse direction.
  • Usually such ships with a symmetrical propeller arrangement are operated according to an empirically determined characteristic. Specifically, this means that the front propeller is driven at approximately 10% lower speed depending on the direction of travel depending on the speed of the rear propeller, in particular in order to avoid as far as possible a braking effect of the front propeller which is not to be used for thrust.
  • the object of the invention is to provide an improved method with an associated arrangement, with which, in particular, the adjustment of the speed of the bow propeller to a value which leads to a favorable overall propulsion energy consumption at any ship speed and any other influencing factors
  • the object is achieved in a method of the type mentioned at the outset in that, in order to optimize efficiency, there is a minimum value regulation of the sum of the active powers absorbed by both drive systems.
  • the associated arrangement for setting the speed of the bow propeller is characterized by a controller with the active powers of both drives as input variables, the speed of the bow propeller being determined in the controller at which the sum of the active powers is a minimum.
  • the method according to the invention can, in particular, supplement a pre-control, which is based on empirical values, for correction. Optimization can also take place when the rear propeller is raised. In the so-called split mode, i.e. when driving slowly in a harbor basin or the like, the helmsman is nevertheless given full freedom to use both drives independently.
  • the single figure shows a schematic block diagram of a minimum value control for ferries.
  • a driving ship is indicated by 1, which has a complete propulsion system both at the bow and at the stern, both of which are constructed identically. As a result, such ships are capable of reversing the direction of travel without turning maneuvers.
  • a first motor with 2 and associated propeller 3 and a second motor with 4 and associated propeller 5 are designated in the figure. Both motors 2 and 4 are controlled via suitable power control elements 6 and 7, which are connected to the vehicle electrical system.
  • the power consumed by the individual motors 2 and 4 can be recorded via transducers 8 and 9.
  • the measured values are fed to a controller 10 and processed there.
  • a summation element 11 is expediently connected upstream of the controller 10, so that the sum of both powers is already input as the input variable.
  • Both motors 2 and 4 are each assigned a unit 12 or 14 for speed control.
  • the unit 14 is coupled to a machine telegraph 15, so that a suitable speed can be specified in the sense of speed control of the ship
  • the controller 10 works as a minimum value controller. Specifically, this means that when a certain speed is specified on the rear propeller and a speed which is usually around 10% lower
  • the speed at the bow propeller with the transducers 8 and 9 detects the power consumed and fed to the controller 10 via the summation element 11.
  • the controller lu adjusts the speed of the front propeller drive until the total value of the active power consumed by the other drive systems is brought to a minimum
  • the minimum value controller 10 is designed as a digital controller. He can thus perform an additional function to the usual drive controls and therefore does not require any additional system sizes as actual control values. When the direction of travel changes, the speed setpoint control of both drive systems can be switched electronically immediately.
  • control concept described can thus be used in a comparatively simple manner to reduce the energy to be used for the overall system. Efficiency optimization is thus achieved.

Abstract

Parmi les bateaux, les navires transbordeurs peuvent en particulier être équipés de systèmes d'entraînement identiques à la proue et à la poupe afin d'éviter au bateau de virer de bord en cas de changement de direction. De manière générale, pendant la marche, la vitesse de rotation de l'hélice avant est inférieure à celle de l'hélice arrière. Selon l'invention, pour optimiser le rendement, la somme des puissances efficaces absorbées des deux systèmes d'entraînement est régulée à une valeur minimale. Dans le système associé, il est prévu un régulateur (10) dont les grandeurs d'entrée sont les puissances efficaces des deux systèmes d'entraînement. La vitesse de rotation de l'hélice de proue à laquelle la somme des puissances efficaces est minimale est déterminée dans le régulateur (10).
