Embodiment
Before describing the embodiments in more detail, it should be understood that and the invention is not restricted to detailed construction in the application hereafter or described in accompanying drawing or arrangement of elements.The present invention can be the embodiment that alternate manner realizes.And, should be appreciated that wording used herein and term are only used as to describe purposes, should being construed as limiting property not explain.Similar wording meant and comprised item listed thereafter, its equivalent and other additional things " comprising " used herein, " comprising ", " having " etc.Particularly, when describing " certain element ", the quantity that the present invention does not limit this element is one, also can comprise multiple.
Fig. 1 is the system schematic of an embodiment of piston engine machine power generating system.As Fig. 1, piston engine machine power generating system comprises piston type master motor 10, main generator 12 and tail-gas power generator 14.
Piston type master motor 10 drives main generator 12 to generate electricity.In existing generator, the excitation system of generator is provided by an excitation generator coaxial with generator shaft usually, and the excitation system of therefore existing design needs the power consuming generator.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 comprises exciting winding 16 and field regulator 26.Exciting winding 16 is arranged on inside main generator 12.Field regulator 26 can be arranged in tail-gas power generator 14, specifically describes below.
Tail-gas power generator 14 utilizes the heat energy power-generating of the tail gas of master motor 10.As shown in Figure 2, in one embodiment, tail-gas power generator 14 comprises turbine 18, retarder 20, generator 22 and inverter 24.
Turbine 18 rotates to be driven by described tail gas in order to receive tail gas from master motor 10.When motor 10 unequipped pressurized machine, the tail gas that turbine 18 receives can be directly obtain from the exhaust valve of motor 10; When motor 10 is equipped with pressurized machine, the tail gas that turbine 18 receives can be obtain from the relief opening of pressurized machine.
The rotation function of turbine 18 by the rear driving generator 22 of retarder 20 to generate electricity.In the present embodiment, generator is permanent magnet generator.Inverter 24 is electrically connected with permanent magnet generator 22 and converts required electric power band dynamic load to the electric power sent by permanent magnet generator 22.Such as, the electric power that permanent magnet generator 22 sends to be converted to the electric power of constant frequency and constant voltage grid-connected to carry out for inverter 24.
The field regulator 26 of excitation system is according to the electric current of the load regulation exciting winding of main generator.In the present invention, the electric power of the excitation system of main generator 12 is provided by tail-gas power generator 14.Tail-gas power generator 14 utilizes the tail gas of master motor 10 to carry out generating electricity, and usually can send the electric power being equivalent to main generator 5-10%.The electric power of this quantity enough ensures the electricity needs of excitation system usually.And owing to providing the tail-gas power generator 14 of electric power independent of main generator 12 for excitation system, therefore the Current adjustment of excitation system will become and be more prone to, and therefore can simplify the design of field regulator.The unnecessary electric power of tail-gas power generator can be grid-connected or for other purposes.In certain embodiments, field regulator 26 can design in the control system of tail-gas power generator 14.
In sum, there is provided herein a kind of piston engine machine power generating system, the electric power of the excitation system of its main generator is supplied by tail-gas power generator.Electric power due to excitation system no longer consumes the power of main generator, therefore can improve the efficiency of generator set.Meanwhile, owing to providing the tail-gas power generator of electric power independent of main generator for excitation system, therefore the Current adjustment of excitation system will become and be more prone to, and therefore can simplify the design of field regulator.
Concept described herein may be embodied to other form when not departing from its spirit and characteristic.Disclosed specific embodiment should be regarded as exemplary instead of restrictive.Therefore, scope of the present invention is by appended claim, instead of determines according to these descriptions before.Any change in the letter and equivalency range of claim all should belong to the scope of these claims.
