Problems solved by technology

Since the diesel generator needs to consume a large amount of diesel oil every time it is tested with a dummy load 1, the energy it generates will eventually be dissipated through the dummy load 1 heat, resulting in serious energy waste

Embodiment 1

[0036] figure 2 A structural diagram of an energy feedback system applied to a generator provided by an embodiment of the present invention. Such as figure 2 As shown, the energy feedback system includes a transformer and rectifier device 4 for connecting with the output end of the generator, and is used to transform and rectify the alternating current output by the generator 3 to output direct current of a predetermined voltage. The transformer and rectifier device 4 is used for To be connected with the energy storage device 5 and / or the actual electric load 2 . figure 2 Dashed lines indicate optional connections.

[0037] It should be noted that the function of the transformer and rectifier is to transform and rectify, so it must include a transformer and a rectifier unit. The transformer is used for voltage conversion, and the rectifier unit is used to adjust parameters such as power during the test process. The transformer can be a step-up transformer or a step-down ...

Embodiment 2

[0051] In the above embodiments, the transformer rectifier device can be connected with any one of the energy storage device and the actual electric load, or both; Powered separately. Figure 4 A structural diagram of another energy feedback system provided by an embodiment of the present invention. Such as Figure 4 As shown, in this embodiment, the electric energy finally output by the generator is connected to the mains grid to supply power to the actual electric load. In this case, the energy feedback system further includes: an inverter and transformer device 6 arranged between the transformer and rectifier device 4 and the actual electric load 2, used to transform and convert the direct current output by the transformer and rectifier device 4 The inverter is used to output alternating current of a predetermined voltage, and the output end of the inverter transformer device 6 is connected to the high-voltage mains incoming cabinet to be connected to the mains grid to su...

Embodiment 3

[0059] In the first embodiment, the transformer and rectifier device can be connected to any one of the energy storage device and the actual electric load, or both. In this embodiment, the transformer rectifier is connected to both the energy storage device and the actual electric load, and the energy storage device is also connected to the actual electric load. For details, see figure 2 .

[0060] Since in this embodiment, except that the energy storage device is connected to the actual electric load, the connection modes and working principles of other devices are the same as those in Embodiment 1, so details are not repeated here. In this embodiment, the purpose of connecting the energy storage device to the actual electric load is to consume the stored electric energy on the energy storage device. In a specific application scenario, the generator test takes half an hour, and the energy storage device and the actual power load are connected to the transformer rectifier de...

Abstract

The invention discloses an energy feedback system applied to a power generator and a power generation system. The energy feedback system comprises a transformation rectification device, wherein the transformation rectification device is connected with an output end of the power generator and is used for connecting an energy storage device and / or an actual power utilization load, and an alternatingcurrent output from the power generator is transformed and rectified to output a direct current of a predetermined voltage for the energy storage device and / or the actual power utilization load during test of the power generator. During the test process of the power generator and with the energy feedback system provided by the invention, on one hand, a rectification unit in the transformation rectification device is a power module, and the test of the power generator can be achieved by adjusting the power module; and on the other hand, the electric energy output from the power generator is consumed on the energy storage device or the actual power utilization load during test, and the energy recycling is achieved. Compared with a dummy load, the system has the advantages that the test costis reduced, and the energy utilization rate is improved.

Description

technical field [0001] The invention relates to the technical field of back-up power supply with dummy load testing, in particular to an energy feedback system and a power generation system applied to generators. Background technique [0002] With the development of big data, cloud computing, Internet of Things, and artificial intelligence, data centers are developing in the direction of high density, large-scale, centralized, and green. Therefore, data security and reliability are becoming more and more important. In order to reduce the problem of data loss caused by sudden power outages, a common method is to equip large data centers with several generators (commonly diesel generators) as backup power sources. [0003] If the generator or generating set is not used for a long time or is operated under low power and under load, it will soon cause carbon deposition, and in severe cases, a unit deflagration accident will occur, which will seriously affect the life of the unit...
