When " certain element ", the quantity that the present invention does not limit the element can also include multiple as one.
Fig. 1 is the system schematic of one embodiment of piston engine electricity generation system.Such as Fig. 1, piston engine generates electricity
System includes piston type sustainer 10, main generator 12 and tail-gas power generator 14.
Piston type sustainer 10 drives main generator 12 to generate electricity.In existing generator, the excitation system of generator
Generally provided by one and the coaxial excitation generator of generator shaft, therefore the excitation system of existing design needs to consume and generated electricity
The power of machine.But in the present invention, the electric power of the excitation system of main generator 12 is provided by tail-gas power generator 14.Excitation system
System includes Exciting Windings for Transverse Differential Protection 16 and field regulator 26.Exciting Windings for Transverse Differential Protection 16 is arranged on the inside of sustainer 12.Field regulator 26 can
It is arranged in tail-gas power generator 14, is specifically described below.
Tail-gas power generator 14 utilizes the heat energy power-generating of the tail gas of sustainer 10.As shown in Fig. 2 in one embodiment,
Tail-gas power generator 14 includes turbine 18, decelerator 20, generator 22 and inverter 24.
Turbine 18 is rotated to receive tail gas from sustainer 10 with being driven by the tail gas.In 10 unequipped increasing of engine
In the case of depressor, the tail gas that turbine 18 receives can directly be obtained from the exhaust valve of engine 10；Equipped in engine 10
In the case of having booster, the tail gas that turbine 18 receives can be the exhaust outlet acquisition from booster.
The rotation function of turbine 18 drives generator 22 to be generated electricity afterwards by decelerator 20.In the present embodiment,
Generator is magneto.Inverter 24 electrically connects the electrical power conversion so that magneto 22 to be sent with magneto 22
Into required electric power band dynamic load.For example, inverter 24 by the electrical power conversion that magneto 22 is sent into constant frequency and constant voltage
Electric power is grid-connected to carry out.
The field regulator 26 of excitation system is according to the electric current of the load regulation Exciting Windings for Transverse Differential Protection of main generator.In the present invention
In, the electric power of the excitation system of main generator 12 is provided by tail-gas power generator 14.Tail-gas power generator 14 is started using master
What the tail gas of machine 10 was generated electricity, the electric power equivalent to main generator 5-10% usually can be sent.The electric power of this quantity leads to
Often ensure the electricity needs of excitation system enough.It is independent to be additionally, since and provide the tail gas engine 14 of electric power for excitation system
It will become to be more prone in the current regulation of main generator 12, therefore excitation system, therefore field regulator can be simplified
Design.The unnecessary electric power of tail-gas power generator can be with grid-connected or for other purposes.In certain embodiments, field regulator 26 can
To be designed in the control system of tail-gas power generator 14.
In summary, there is provided herein a kind of piston engine electricity generation system, the electric power of the excitation system of its main generator
It is to be supplied by tail-gas power generator.Because the electric power of excitation system no longer consumes the power of main generator, therefore hair can be improved
