Field of the Invention The present invention relates to a power generation device capable of frequency conversion, and more particularly, to a power generation device capable of performing frequency conversion that can be changed to a required frequency form and supplied to a ship.

Generally, ships are equipped with various electric devices, and frequency and frequency systems are provided for each use.

At this time, different frequencies and frequencies may be required between equipment depending on the manufacturer or the production environment, so that a device capable of changing the form of frequency and frequency is required.

The present invention provides a power generation device capable of frequency conversion by changing to a necessary frequency form and supplying it to a ship.

A power generation device capable of frequency conversion according to an embodiment of the present invention includes: a pony motor; A synchromotor connected to the pony motor; A synchro generator connected to the synchromesh; And a control panel capable of drivingly controlling the pony motor, the synchromesh and the synchro generator to change and adjust the required frequency form.

The synchronous motor and the synchronous generator are made in a brushless manner.

The synchronous motor and the synchro generator are frequency-adjusted within ± 10% within a rated rotational speed range for an arbitrary load between a power factor of 0.8 and 1.0.

The frequency adjustment range of the synchromesh and the synchro generator is set by an increase / decrease signal by a dry type contact.

The control panel can be set to operate in series or in parallel. When the parallel operation is set, the synchronous-scope pointer positions of the synchronous motor and the synchronous generator are set to the same point.

The synchronous generator is limited in parallel operation by the control panel during operation in a manual voltage regulator (MVR) mode.

According to the power generation apparatus capable of frequency conversion according to the embodiment of the present invention, it is possible to change the frequency form to be supplied to the ship.

In addition, using a brushless synchronous motor and a synchro generator, no external power source is required, which can reduce the trial run cost.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other features and advantages of the present invention will become more apparent by describing in detail exemplary embodiments thereof with reference to the attached drawings in which: It is intended that the invention be described in its entirety by reference to the appended claims and their equivalents.

In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

Hereinafter, a power generation device capable of frequency conversion according to an embodiment of the present invention will be described with reference to the accompanying drawings.

1 to 3 are schematic views of a power generation apparatus capable of frequency conversion according to an embodiment of the present invention.

1 to 3, a power generation apparatus 100 capable of frequency conversion according to an embodiment of the present invention includes a control panel 110, a pony motor 120, a synchromotor 130, 140).

At this time, the pony motor 120, the synchronous motor 130, and the synchronous generator 140 are sequentially arranged and have the same axial center as shown in the figure.

First, the control panel 110 drives and controls the pony motor 120, the synchromesh 130, and the synchros generator 140.

At this time, the pony motor 120 corresponds to an input started by the control panel 110, and the synchronous generator 140 corresponds to an output.

The synchromesh 130 and the synchro generator 140 are formed in a brushless manner. At this time, the self-excitation mode does not require a separate external power supply for excitation since there is no brush.

Here, the synchronous motor 130 and the synchronous generator 140 include a stator winding (not shown) in which an alternating current flows as a rotating stator type, a DC stator winding (not shown) and a stator winding And a cylindrical field (not shown) composed of a braking winding (not shown).

The AC power generated in the exciter (not shown) is rectified to DC power by a rotary rectifier module (not shown) and supplied to the main winding (not shown), and the rotary rectifier module is firmly fixed to the shaft.

The synchronous motor 130 and the synchromesh generator 140 are frequency-adjusted within ± 10% within a rated rotational speed range for an arbitrary load between a power factor of 0.8 and 1.0.

At this time, the frequency adjustment range is set by an increase / decrease signal by a contact of dry type.

On the other hand, the control panel 140 can be set to operate in series or in parallel.

At this time, when the control panel 140 is set to the parallel operation, the synchro-scope pointer positions of the synchromotor 130 and the synchro generator 140 are set at the same point.

Preferably, the synchro generator 140 is limited in parallel operation by the control panel during operation in the manual voltage regulator (MVR) mode.

4 is a block diagram schematically illustrating an operation relationship between the configurations of a power generation apparatus capable of frequency conversion according to an embodiment of the present invention.

4, a power generation apparatus 100 capable of frequency conversion according to an embodiment of the present invention includes a control panel 110, a pony motor 120, a synchromesh 130, and a synchro generator 140 .

Since the above-described configurations are the same as those described above with reference to FIG. 1 to FIG. 3, redundant description will be omitted. However, the above-described contents may be partially overlapped to help understand the drawings.

As shown, the pony motor 120, the synchronous motor 130, and the synchronous generator 140 are connected in series and have the same axial center.

At this time, the control panel 110 can input the inputs in the set range in order to change the pony motor 120, the synchronous motor 130, and the synchronous generator 140 into the required frequency form.

At this time, the set range means a range in which the environment can be set according to the type of the required frequency.

Each of the above-mentioned configurations has predetermined rated information, and as the control panel 110 sets the input value in the rating information, the frequency type can be changed and the changed frequency type can be supplied to the ship .

As described above, the power generation device capable of frequency conversion according to an embodiment of the present invention can be changed to a necessary frequency form and supplied to the ship.

In addition, using a brushless synchronous motor and a synchronous generator, a separate external power source is not required, which can reduce the cost of commissioning.
