Fig. 1 is the figure of the structure for the electricity generation system that outlined one embodiment of the present invention.
Specific implementation mode
Illustrate the electricity generation system of one embodiment of the present invention referring to Fig.1.
As shown in Figure 1, this electricity generation system includes diesel-driven generator 10, the binary system power generation dress comprising binary system generator 23
Set 20, connecting line 31, connection shutter S1, branch line 32, branch shutter S2, resistance R and control unit 40.The electricity generation system
It is equipped on ship.
The output of diesel-driven generator 10 is connected to system in ship.That is, load of the diesel-driven generator 10 into ship
It supplies electric power.In the present embodiment, the rated power of diesel-driven generator 10 is 1000kW or less.
Binary system power generator 20 include evaporator 21, expanding machine 22, binary system generator 23, condenser 24, pump 25 with
And it is sequentially connected evaporator 21, expanding machine 22, condenser 24 and the circulation stream 26 for pumping 25.
Evaporator 21 is by making working media and heat medium（The steam etc. in board generated）It exchanges heat to make working media
Evaporation.
The position in the downstream side of evaporator 21 in circulation stream 26 is arranged in expanding machine 22.Expanding machine 22 makes from evaporator 21
The expanding working medium of the gas phase of outflow.In the present embodiment, work Jie having using gas phase is used as expanding machine 22
The expansion energy of matter and the positive displacement screw expander of rotor being driven in rotation.
Binary system generator 23 is connected to expanding machine 22.Specifically, binary system generator 23, which has, is connected to described turn
The rotary shaft of son（It is not shown）, be fixed on the mover of rotary shaft and configure stator around mover.Binary system generator
23 rated power is less than the rated power of diesel-driven generator.For example, the rated power of binary system generator 23 is 100kW.
The position in the downstream side of expanding machine 22 in circulation stream 26 is arranged in condenser 24.Condenser 24 is by making from expansion
The working media that machine 22 flows out and cooling medium（Seawater etc.）It exchanges heat to make working media condense.
The position in the downstream side of condenser 24 in circulation stream 26 is arranged in pump 25（Between condenser 24 and evaporator 21
Position）.The working media of the liquid phase flowed out from condenser 24 is delivered to evaporator 21 by pump 25 with defined pressure.
The output of binary system generator 23 is connected to the output of diesel-driven generator 10 by connecting line 31.That is, diesel oil
The output of generator 10 and the output of binary system generator 23 are supplied to the load in ship.
Shutter S1 is connected to be arranged on connecting line 31.The output of shutter S1 switching binary system generator 23 is connected to bavin
The confluence of the output of fry dried food ingredients motor 10 and blocking.
Branch line 32 is from 31 branch of connecting line.Branch shutter S2 and resistance R are arranged on branch line 32.Branch's shutter
S2 switches input and blocking of the output of binary system generator 23 to resistance R.In addition, as shown in Figure 1, in binary system power generator
When 20 quiet rum, connection shutter S1 is connected, and branch shutter S2 is disconnected.
Control unit 40 disconnects opening and closing when receiving the abnormal signal for the output abnormality for indicating binary system generator 23
Device S1 simultaneously connects branch shutter S2.In the present embodiment, control unit 40 is when receiving the abnormal signal, also allow two into
Generator 23 processed stops.In addition, the abnormal signal is when the rotary shaft of binary system generator 23 crosses rotation, binary system generator
23 temperature be more than a reference value when, binary system generator 23 converter detect when overvoltage or overcurrent when sent out
It is sent to control unit 40.
As described above, in this electricity generation system, due to being arranged in connecting line in the output abnormality of binary system generator 23
31 connection shutter S1 is disconnected（Connecting line 31 is interdicted）, therefore, diesel oil when inhibiting the output abnormality of binary system generator 23
The output system of generator 10 becomes unstable.
In addition, control unit 40 disconnects shutter S1 when receiving the abnormal signal and connects branch's shutter
S2.Therefore, the electric power generated in the generator when the output abnormality of binary system generator 23 will not reach diesel-driven generator 10
Output line, but be effectively consumed in the resistance R for being connected to branch line 32.
Moreover, control unit 40 when receiving the abnormal signal, allows binary system generator 23 to stop, therefore, controlling
It is gradual that portion 40 receives the electric power that the generator generates during the abnormal signal rises until binary system generator 23 stops
Decline.Therefore, the enlargement of resistance R is avoided.
Here, summarizing embodiments described above.
