Problems solved by technology
[0008] However, in the invention disclosed in Patent Document 1, the premise is that each propulsion device has the same structure. Therefore, if a common control signal is applied to propulsion devices of different structures, the mechanical characteristics and control characteristics are different, so there is a difficulty. The problem of achieving synchronization
[0009] In addition, in the invention disclosed in the above-mentioned Patent Document 2, the time constant of the power source with a large time constant of the rotation speed, that is, the time constant of the power source with a fast response speed to the control instruction is matched with that of the power source with a small time constant, that is, the power source with a small time constant. The rotational speed of a power source with a slow response to control instructions fluctuates. Therefore, in the case of voyages with little speed fluctuations and low control frequency, such as ocean voyages, frequent output to a power source with a small time constant may not be necessary. problem with control signal

Provided are a control device for collectively controlling the main engine control devices of a plurality of propulsion devices with different power sources, a ship provided with the same, and a unified control method. The unified control device (80) controls the first main engine control device (61) of the propulsion steam turbine (10) and the time constant of the control output change is smaller than the time constant of the propulsion electric motor (20) of the propulsion steam turbine (10). The second main engine control device (62) performs unified control, wherein the first main engine control device (61) is equipped to control the propulsion steam turbine (10) with the control information of the propulsion electric motor (20) as the target value during the ocean voyage. ) of the ocean voyage mode.
Description
technical field [0001] The present invention relates to a control device, a ship equipped with the control device, and a unified control method, more specifically, to a control device having a plurality of propulsion devices based on different power sources, and a ship provided with the control device, and Unified method of control. Background technique [0002] In ships with several propulsion shafts, for example in steam turbine ships with two propulsion shafts, the propulsion devices are independent of each other on each shaft. Here, regarding the control for synchronizing the rotational speeds of the independent shafts of a twin-machine twin-shaft steam turbine, Patent Document 1 discloses an invention that automatically synchronizes the rotational speeds. [0003] In addition, a case where the power source of each propulsion device is different is also considered. Patent Document 2 discloses an invention related to a hybrid propulsion system in which different types o...
