Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The inventor finds that when the rotating speed of an engine in the generator set is slow, the torque is small, the torque obviously rises along with the increase of the rotating speed, and the torque is large enough only when the rotating speed of the engine reaches a certain value, so that the rotor of the generator can be driven to rotate to generate electricity. Therefore, the conventional generator set takes a long time from starting to supplying power, and normally needs several minutes to supply power normally.
The inventor further finds that the rotating speed of the engine in the generator set in an idling state cannot be too low, otherwise the engine is shut down due to the fact that the rotor of the generator is not moved when power generation is needed. Thus, a certain rotation speed of the engine at idle speed needs to be ensured, and thus, the oil consumption of the engine at idle speed is also high.
As a first embodiment of the present invention, as shown in fig. 2, in this embodiment, two starting circuits are connected to the generator, and the first starting circuit is provided with a starting source by the engine; the second starting circuit is provided with a starting source by a motor, the output end of the motor is directly connected with the rotor of the generator, the input end of the motor is connected with a battery pack, and meanwhile, the battery pack is connected with the engine. Preferably, the battery pack is a high-power secondary battery pack, and the high-power output secondary battery can be one of a lithium ion battery, a nickel-metal hydride battery, a nickel-cadmium battery, a lead-acid battery and a super capacitor, or a combination of several of the above batteries, such as a combination of a super capacitor and a lithium ion battery, or a combination of a super capacitor and a lead-acid battery. Similarly, the engine in the present embodiment may be a diesel engine or a gasoline engine. In the embodiment, two starting circuits are arranged for the generator, on one hand, when the response time of the engine in the first starting circuit is too long, the generator can be started by the motor in the second starting circuit; on the other hand, when any one line fails, the other starting line can drive the generator to normally supply power, so that the generator can be quickly started in time, and the working reliability and effectiveness of the generator can be ensured. The working process can be as follows: the two starting circuits run simultaneously, and due to the characteristics of the motor, the torque of the motor in the second starting circuit can reach the maximum value at once, so that the generator is driven to rotate instantly, and the generator can supply power normally within seconds. After several minutes, when the rotating speed of the engine in the first starting circuit reaches a certain value, the engine drives the generator to drive the generator to generate electricity, and meanwhile, the motor in the second starting circuit stops driving the generator. This greatly shortens the time from start-up to normal power supply of the generator. In addition, owing to be equipped with the second starting circuit, the rotational speed when can reducing the engine idle like this stops the engine even, consequently, the utility model discloses greatly reduced the oil consumption of engine when the idle, reduced the emission. When the generator needs to be started again, the motor in the second line can be used for driving the generator to supply power until the rotating speed of the engine in the first starting line reaches a certain value. Therefore, the oil consumption of the generator set in standby is greatly reduced.
As an improvement of the first embodiment of the present invention, as shown in fig. 3, the present invention further includes a motor controller, the motor controller is electrically connected to the battery pack and the motor; the auxiliary starting system is electrically connected with the engine and the battery pack; and the generating set controller is electrically connected with the engine, the generator, the auxiliary starting system and the motor controller.

After several minutes, when the rotating speed of the engine in the first starting circuit reaches a certain value, the engine drives the generator to drive the generator to generate electricity, and meanwhile, the motor in the second starting circuit stops driving the generator. This greatly shortens the time from start-up to normal power supply of the generator. In addition, owing to be equipped with the second starting circuit, the rotational speed when can reducing the engine idle like this stops the engine even, consequently, the utility model discloses greatly reduced the oil consumption of engine when the idle, reduced the emission. When the generator needs to be started again, the motor in the second line can be used for driving the generator to supply power until the rotating speed of the engine in the first starting line reaches a certain value. Therefore, the oil consumption of the generator set in standby is greatly reduced.

The working process can be as follows: the two starting circuits run simultaneously, and due to the characteristics of the motor, the torque of the motor in the second starting circuit can reach the maximum value at once, so that the generator is driven to rotate instantly, and the generator can supply power normally within seconds. After several minutes, when the rotating speed of the engine in the first starting circuit reaches a certain value, the engine drives the generator to drive the generator to generate electricity, and meanwhile, the motor in the second starting circuit stops driving the generator. This greatly shortens the time from start-up to normal power supply of the generator. In addition, owing to be equipped with the second starting circuit, the rotational speed when can reducing the engine idle like this stops the engine even, consequently, the utility model discloses greatly reduced the oil consumption of engine when the idle, reduced the emission.
