Utility model content
For the deficiencies in the prior art, the diesel engine generator parallel control system that provides a kind of intellectuality high is provided the purpose of this utility model.
For achieving the above object, the utility model adopts following technical scheme:
A kind of diesel engine generator parallel control system, it comprises electromagnetic relay, urban electric power switch, some diesel generating sets, controller, voltage regulating module and the circuit breaker identical with diesel generating set quantity;
One mains supply connects load by urban electric power switch, the sense terminal of each controller is connected between this mains supply and this urban electric power switch by this electromagnetic relay, each diesel generating set connects the control end of a corresponding controller, the adjustable side of each controller connects a corresponding diesel generating set by a corresponding voltage regulating module, each diesel generating set is connected between this urban electric power switch and this load by a circuit breaker of correspondence, and each controller is connected by CAN order wire.
Further, this controller is IG-NT control module.
The beneficial effects of the utility model are as follows:
Above-mentioned utility model can, according to the electric power thus supplied automatic open close diesel generating set of civil power, be supervised without people, convenient and safe.In addition, each controller is connected by CAN order wire, can have according to the automatic power distribution output of each diesel generating set the size of power and inactivity.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the preferred embodiments of the utility model diesel engine generator parallel control system.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
Refer to Fig. 1, the utility model relates to a kind of diesel engine generator parallel control system, and its preferred embodiments comprises electromagnetic relay, urban electric power switch, some diesel generating sets, controller, voltage regulating module and the circuit breaker identical with diesel generating set quantity.
One mains supply connects load by urban electric power switch, the sense terminal of each controller is connected between this mains supply and this urban electric power switch by this electromagnetic relay, each diesel generating set connects the control end of a corresponding controller, the adjustable side of each controller connects a corresponding diesel generating set by a corresponding voltage regulating module, each diesel generating set is connected between this urban electric power switch and this load by a circuit breaker of correspondence, each controller is by CAN(Controller Area Network, controller local area network) order wire is connected.
In the time of municipal power failure or power failure, the state of this electromagnetic relay changes, and makes each controller start corresponding diesel generating set, and controls breaker closing, to make diesel generating set produce electricity by circuit breaker supply load.Normal when city power recovery, the state of this electromagnetic relay changes again, makes each controller close corresponding diesel generating set.
All controllers are connected formation control device group by this CAN order wire, thereby can there is the size of power and inactivity according to the automatic power distribution output of each diesel generating set, and make voltage, frequency, the phase angle of each diesel generating set consistent with common bus.
In the present embodiment, this controller is IG-NT control module.
For a person skilled in the art, can be according to technical scheme described above and design, make other various corresponding changes and distortion, and these all changes and distortion all should belong to the protection range of the utility model claim within.
