DETAILED DESCRIPTION

[0023] The technical scheme in the embodiments of the utility model is described clearly and completely below in conjunction with the accompanying drawings. Figures 1-3 The technical scheme in the embodiments of the utility model is described clearly and completely below in conjunction with the accompanying drawings.

[0024] Embodiment one

[0025] Referring to Figure 1 A new energy station power detection system, including data acquisition module 1, data processing module 2, control module 3 and fault processing module 4, wherein data acquisition module 1 is connected with data processing module 2, data processing module 2 is connected with control module 3, and control module 3 is connected with fault processing module 4.

[0026] And data acquisition module 1 includes power sensor, and by setting power sensor to the detection point in new energy station, thereby obtaining the power signal at different positions in new energy station. Meanwhile, data processing module 2 is configured to process the information collected by data acquisition module 1, and transmits the processing result to control module 3.

[0027] Referring to Figure 2 Data processing module 2 includes power divider 5, attenuator 6, adjustable phase shifter 7, amplifier 8 and power detector 9 connected in sequence. And the power divider 5 is used for receiving the power signal data obtained by the power sensor in data acquisition module 1, and dividing the power signal data equally in power. In this embodiment, the obtained power signal data is divided into N paths of equal power signals.

[0028] With the continuous expansion of the new energy station grid connection, the power signal to be measured is more and more complex, and the existing method is still to transmit the power signal directly to the power detector 9 for analysis after obtaining the power signal, so that the abnormal information and characteristic information in the power signal are easily hidden or buried, causing the power detector 9 to fail to detect the abnormal state. The power divider 5 is used to divide the original extremely complex power signal and analyze it respectively to more accurately find the abnormal characteristic information in the power signal, so as to ensure the normal operation of the new energy station.

[0029] The original power signal is divided by the power divider 5, so that the divided power signal does not meet the test range of the power detector 9, and thus cannot be analyzed and processed. Therefore, the amplitude and phase of the power signal processed by the power divider 5 are adjusted by the attenuator 6 and the adjustable phase shifter 7 in turn, so that the divided power signal meets the test range of the power detector 9.

[0030] At the same time, the original power signal is divided into N equal power signals, so the number of attenuators 6 and adjustable phase shifters 7 in this embodiment is also N, and the N equal power signals divided by the power divider 5 are input into an attenuator 6 respectively. Moreover, the attenuator 6 and the adjustable phase shifter 7 have a one-to-one correspondence.

[0031] However, the power signal divided by the power divider 5 still cannot exhibit the characteristic information and abnormal characteristics in the signal. Therefore, the power signal processed by the adjustable phase shifter 7 is transmitted to the amplifier 8 to realize amplification processing of the power signal, so as to reflect the characteristic information and abnormal characteristics in the power signal.

[0032] The power signal is processed by the power divider 5, the attenuator 6, the adjustable phase shifter 7 and the amplifier 8 in turn, and then the power signal is analyzed. The power detector 9 can analyze whether there is an abnormal state in the power signal. The number of amplifiers 8 and power detectors 9 is also N, and the amplifier 8 and the adjustable phase shifter 7, the amplifier 8 and the power detector 9 also have a one-to-one correspondence.

[0033] Through the above scheme, the characteristic information in the power signal can be further mined to accurately identify whether there is an abnormal state in the power signal and ensure the normal operation of the new energy station. The power sensor, the power divider 5, the attenuator 6, the adjustable phase shifter 7, the amplifier 8 and the power detector 9 can be connected by wired connection.

[0034] The power detector 9 transmits the result to the control module 3 after analyzing and processing the power signal; the control module 3 needs to control the fault processing module 5 to process the fault according to the processing result transmitted by the data processing module 2. The control module 3 can adopt a chip with model FM33G028.

[0035] With reference to Figure 3 The fault processing module 5 comprises an NB-IOT communication unit 10, a display unit 11 and a Bluetooth communication unit 12; the NB-IOT communication unit 10, the display unit 11 and the Bluetooth communication unit 12 are connected with the control module 3.

[0036] Meanwhile, the fault processing module 5 further comprises a cloud monitoring system 13, and the cloud monitoring system 13 is connected with the NB-IOT communication unit 10; the control module 3 transmits the processing result to the cloud monitoring system 13 through the NB-IOT communication unit 10, and the cloud monitoring system 13 can monitor the processing result in real time, so as to ensure the normal operation of the new energy station and discover the abnormal state in the new energy station in time. The cloud monitoring system 13 can adopt an existing cloud monitoring system.

[0037] Moreover, the fault processing module 5 further comprises a mobile terminal 14, and the mobile terminal 14 is connected with the Bluetooth communication unit 12; when the abnormal state occurs in the new energy station, the control module 3 can transmit the fault information to the mobile terminal 14 according to the Bluetooth communication unit 12; the mobile terminal 14 can be a mobile phone, a computer or the like, so as to receive the fault information in the first time and maintain the new energy station.

[0038] In the embodiment, the display unit 11 comprises a liquid crystal display, which is used for displaying the processing result obtained by the control module 3.

[0039] The above describes the specific embodiments of the utility model with reference to the drawings, but is not limited to the protection scope of the utility model, and those skilled in the art should understand that various modifications or deformations made by those skilled in the art on the basis of the technical scheme of the utility model without creative labor are still within the protection scope of the utility model.
