The present invention relates to a control device for a marine electric power generator (MG device). Conventionally, a ship's power supply circuit is sometimes equipped with a DC motor or the like controlled by an SCR unit. The conventional power supply circuit in this case is explained using the schematic wiring diagram shown in Fig. 1. 1 is the main generator, 2 is the main switchboard, 3 is the cable disconnector, 4 is the SCR unit,
5 is a regular low voltage circuit transformer, 6 is a regular low voltage circuit M-G device, 7 is a regular low voltage power supply board, 8 is a power switch, 9 is an emergency switchboard, 10 is an emergency generator, 11 is a transformer for an emergency low voltage circuit, 12 is an MG device for an emergency low voltage circuit, 13 is an emergency low voltage power supply board, and 14 is a breaker. In the conventional device having the above configuration, a load that is resistant to noise generated by the SCR unit (thyrist) 4 is connected to the normal low voltage circuit transformer 5 and the emergency low voltage circuit transformer 11. However, computers and wireless devices are susceptible to noise, so they cannot be directly powered, and M-
A G device 6 and an MG device 12 for emergency low voltage circuit are provided and connected to a load that is susceptible to noise. As a result, although the normal low voltage circuit MG device 6 and the emergency low voltage circuit MG device 12 are not required when the SCR unit 4 is not operating, the SCR unit 4 does not operate. It is necessary to keep the MG devices 6, 12 in continuous operation regardless of whether the MG devices 6, 12 are being operated or not, and there are problems with the maintenance of the MG devices 6, 12 and the noise generated. This invention was proposed in view of the above circumstances, and its purpose is to improve the operation of the M-G device.
By only supplying power when the SCR unit is operating, and at other times, supplying power from other circuits, without affecting noise-sensitive equipment.
Moreover, it is an object of the present invention to provide a marine electric power generator that can minimize the maintenance of the MG device and the generation of noise. In other words, the control device for a marine electric power generator according to the present invention controls the noise-sensitive load when the SCR unit and the transformer are operating, and controls the noise-sensitive load and the noise-resistant load when the transformer is malfunctioning. an electric power generator that supplies power to each of the
The transformer is configured to supply power to the noise-resistant load when the SCR unit is in operation, and to the noise-resistant load and the weak load when the SCR unit is stopped, The operation of the -G equipment is stopped when the SCR unit is not operating, and the transformer is used to supply power to noise-sensitive loads, and in the event of a transformer failure, the M-
This is a control device for a marine electric power generator that reduces the maintenance of the M-G device and the generation of noise to a minimum by supplying power to noise-resistant loads using the G device. Next, one embodiment of the present invention will be described in detail based on FIG. In Fig. 2, 21 is an alternating current generator, 22 is a generator sheath breaker, 23 is a generator busbar, and 24 is a
SCR device, 25 is the DC motor, 26 is the power supply side of the MG device, 27 is the controller of the MG device, 28 is the MG device, and 29 is the secondary side of the MG device. 30 is the power supply side disconnector of the transformer, 3
1 is a transformer, 32 is a bus that feeds power to a load group that is resistant to SCR noise, 33 is a bus that feeds a load group that is sensitive to SCR noise, 34 is a load group that is resistant to SCR noise, and 35 is a bus that is weak to SCR noise. load group,
36 is a bus tie breaker that connects the bus that feeds the SCR noise-resistant load group and the SCR noise-susceptible load group, and 37 is the transformer 2.
This is the next side disconnection. Next, the operation of the above embodiment of the present invention will be explained. First, the AC generator 21 and the generator breaker 2
2, power is supplied to the generator bus 23. in this case
While the SCR device 24 and the DC motor 25 are in operation, noise is generated by the SCR device 24 and transmitted to the generator bus 23 . However, as mentioned above, it is not possible to supply power to computers, radios, etc. while generating noise, so the power supply to the load group 35, which is susceptible to noise in these SCRs, is carried out by using the generator bus 2.
3 → Power supply side sheath breaker 26 → Controller 27 → M-G device 28 → Secondary side sheath breaker 29 → Bus bar 33 → SCR
This is done in the system of load group 35, which is susceptible to noise.
In this case, the bus tie breaker 36 is opened. On the other hand, load group 34 that is resistant to SCR noise such as lighting equipment
Power is supplied to the generator bus 23 → power supply side sheath breaker 30 → transformer 31 → secondary side sheath breaker 37 → bus 3
This is done in the system of load group 34, which is resistant to 2→SCR noise. That is, as mentioned above, the bus tie breaker 36 is opened and the M-G device 28 is used to supply power to the load group 35 that is susceptible to SCR noise, while the
To feed power to the load group 34 that is resistant to SCR noise,
A transformer 31 is used. On the other hand, if the transformer 31 breaks down in this state, the power supply side sheath breaker 30 and the secondary side sheath breaker 37 are opened to stop the transformer 31, and the bus tie breaker 36 is closed. - From G device 28
Power is also supplied to a load group 34 that is resistant to SCR noise.
In this case, the power supply system to the SCR noise-resistant load group 34 and the SCR noise-sensitive load group 35 is as follows: generator bus 23 → power supply side disconnector 26 → controller 27 → M-G device 28 → Secondary side disconnector 29
→ Bus bar 33 → Bus tie breaker 36 → Bus bar 32 →
SCR noise-resistant load group 34 and bus bar 33
→This becomes load group 35, which is vulnerable to SCR noise. SCR
While the device 24 and the DC motor 25 are stopped,
Since no noise is generated by the SCR device 24,
The M-G device 28 is stopped and the power supply side disconnector 26,
The secondary side sheath breakers 29 are both open. At this time,
Power is supplied to the SCR noise-resistant load group 34 and the SCR noise-sensitive load group 35 from the generator bus 23.
→ Power supply side sheath breaker 30 → Transformer 31 → Secondary side sheath breaker 37 → Bus bar 32 → SCR noise-resistant load group 34 and bus bar 32 → Bus tie breaker 36 →
This is done in the system of the load group 35, which is susceptible to noise from the bus 33→SCR. When power is simultaneously supplied to the SCR noise-resistant load group 34 and the SCR noise-susceptible load group 35, the bus tie breaker 36 is closed. As is clear from the above explanation, the output ratings of the M-G device 28 and the transformer 31 are approximately equal, and the load group 34, which is resistant to SCR noise,
It is determined so that power can be simultaneously supplied to the load group 35 that is susceptible to SCR noise. Further, in a system in which the power supply voltages supplied to the generator bus 23, the bus 32, and the bus 33 are all equal, the transformer 31 may be omitted. That is, the generator bus 23 → power side sheath breaker 30 → transformer 31 → secondary side sheath breaker 37 → bus 32 is as follows: generator bus 23 → power side sheath breaker 30 → secondary side Switch breaker 37 → Bus bar 32 or generator bus bar 2
3→power supply side disconnector 30→bus bar 32. As described above, according to the present invention, the following uses can be made. Note that (strong) is load group 3 that is resistant to noise.
4. (Weak) is the load group 35 that is susceptible to noise, (Variable) is the transformer 31, and (MG) is the MG device 28.

Only when the SCR unit is operating, in other cases, that is, when the SCR unit is stopped, the MG device is stopped, and power is also supplied to noise-sensitive loads by other circuits such as transformers. However, if the transformer fails, power cannot be supplied as is, so the MG device is configured to supply power even to noise-resistant loads. Therefore, it is possible to reduce the influence of noise with a small volume in a marine power generation device with many restrictions, and to have an excellent effect of not causing abnormality on the load side even if a failure occurs.
