step 1, a single machine information file of the wind driven generator is gathered to the SCADA server 12 through an optical fiber ring network. And starting the data acquisition interface backskend-modbus service of the SCADA server 12, and starting to transmit real-time data and/or historical data. The single machine information file of the wind driven generator is collected into the SCADA server 12 through a modbus protocol (or iec protocol, opc-ua protocol) of the optical fiber ring network.

And 2, determining whether the transmission of the real-time data and/or the historical data is normal. If not, namely the transmission of the real-time data and/or the historical data is abnormal, the step 1 is returned. If so, that is, the transmission of the real-time data and/or the historical data is normal, step 3 is executed.

And step 3, acquiring real-time data and/or historical data through a data acquisition interface of the SCADA server 12, storing the real-time data into a redis database in the SCADA server 12 in real time, and storing the historical data into a mongo database.

And step 4, after the real-time data is received by the redis database in the SCADA server 12 and the historical data is received by the mongo database, whether the forward isolation device 13 is penetrated is determined. If not, returning to the step 1. If so, that is, the data of the SCADA Server 12 penetrates through the forward isolated sending interface 121 to implement sync Server service, so that the real-time data and the historical data can be transmitted to the intranet isolation channel 21 of the network card 20 of the forward isolation device 13, and the forward isolation device 13 pushes the real-time data and the historical data to the extranet isolation channel 22 of the network card 20 through the intranet and extranet isolation segmented secure transmission technology in the network card 20. And executing the step 5.

And step 5, the data of the single machine uploading server 14 penetrates through the forward isolated receiving interface 141 to realize sync Client service, so that the real-time data and the historical data of the external network isolation channel 22 of the network card 20 outside the isolation can be received, and the real-time data is stored in a redis database in the single machine uploading server 14 in real time and the historical data is stored in a mongo database.

And 6, determining whether the single machine information file is normally generated. If so, namely, the stand-alone information file is normally generated, step 8 is executed. If not, namely the stand-alone information file cannot be normally generated, executing the step 7.

And 7, determining whether the wind power plant is abnormally powered off, and if so, turning on the power supply again to generate a simulation file. If not, generating a single machine information file containing the running state and the fault mode of the wind driven generator, and then executing the step 8.

And step 8, the single machine uploading server 14 generates a single machine information file meeting the format requirement of the power grid dispatching center 11 through the sftp service, and transmits the encrypted single machine information file to the power grid dispatching center 11 in an encrypted form at regular time to complete the whole business process.

The embodiment of the utility model provides an in, wind-powered electricity generation field leads to the unit information file disappearance to be examined by grid dispatching center 11 because the power failure in the frequent field, use and upload the system 10 back based on the unit information file of SCADA server 12, not only can accomplish automatic upload function under normal conditions, and can also combine WinSCP to accomplish the function that the unit information file supplyes and pass under emergency such as unusual outage in addition, can interrupt the aerogenerator communication and aerogenerator trouble condition real-time transmission can also effectively avoid unusual outage to cause the unnecessary examination for the wind-powered electricity generation field when for province's dispatch center. Therefore, on the basis of ensuring the network information safety, the whole service uploaded by the single machine is smoothly completed, and the operation and maintenance efficiency of the work is greatly improved. The WinSCP is an open source graphical SFTP client using SSH (encapsulation of Struts, spring, hibernate, flow control, service flow, database operation) in a Windows environment.

Fig. 5 is a schematic diagram of an interface 30 for uploading a single-machine information file according to an embodiment of the present invention. Fig. 6 is a schematic diagram illustrating the details of the reissued single-machine information file according to the embodiment of the present invention.

The interface 30 for uploading the stand-alone information file shown in fig. 5 includes an interface of the stand-alone upload server 14 and an interface of the power grid dispatching center 11, and an IP address of the SFTP service of the stand-alone upload server 14 is used as a source address of the stand-alone information file. And the IP address of the SFTP service of the power grid dispatching center 11 is used as the destination address of the single machine information file.

FIG. 6 shows details of the reissued individual information file. The # shown in fig. 6 indicates the number of the single-machine information file to be reissued. With reference to fig. 5, as shown in fig. 6, the platform based on the SCADA server 12 coordinates sftp and the transmission interface 121 where data penetrates through the forward isolation, simulates a simulation file closest to real data with reference to a previous single-machine information file of the same machine type at the same wind speed, writes the simulation file into the single-machine information file, modifies the date, time, file name, and active and idle data in the single-machine information file, and then pushes the modified data to the power grid dispatching center 11 through the WinSCP. In addition, according to the generation condition of the single-computer information file, manual judgment and modification can be carried out by checking whether the sizes of the single-computer information files are consistent, and the sizes of the single-computer information files are consistent, so that the file generation is not wrong, wherein the single-computer information file is XXX _20210110 \u0000.DJ, and the file size is about 107 k.
