[0029] The present invention will be further described below in conjunction with the drawings and specific embodiments:

[0030] The specific embodiment is as follows Figure 1As shown in the figure, the present invention is a new energy single - unit information uploading and management system, including a computer storage server cluster, a real - time data server, a computing server, and an application publishing server provided on the main station side. On the station side, there is a new energy single - unit uploading server. The new energy single - unit uploading server is data - connected to the computer storage server cluster. The computer storage server cluster is data - connected to the real - time data server. The real - time data server is data - connected to the computing server. The computing server is also data - connected to an existing system. The application publishing server is data - connected to the real - time data server.

[0031] The application publishing server is data - connected to the computer storage server cluster.

[0032] The new energy single - unit uploading servers are respectively set up at each station and are matched with the number of generating units.

[0033] The new energy single - unit uploading server is a computer networked with the computer storage server cluster. The computer storage server cluster includes multiple groups of computing and storage servers.

[0034] The existing system is the D5000 system, which is the basic platform of a new - generation intelligent power grid dispatching technical support system and can be applied to photovoltaic and wind power stations. The data obtained by this system from the D5000 system includes: data of photovoltaic and wind turbine monitoring systems, data of anemometer towers, and location and capacity data of wind - solar power stations. The new energy single - unit uploading servers set up at the stations will obtain the data of single - unit wind power / photovoltaic units. The photovoltaic single - unit data mainly includes: active power, reactive power, back - panel temperature, photovoltaic number, installed capacity, etc. The wind power single - unit data mainly includes: wind speed, active power, reactive power, ambient temperature, wind turbine number, installed capacity, etc. The above - mentioned information is uploaded to the computer storage server cluster for storage through the reserved ports of the firewall. The computing server accesses the computer storage server cluster to pull the single - unit data of photovoltaic and wind power, and after data processing, transfers it to the real - time data server. The real - time data server serves as a cache server for the application publishing server to retrieve, or stores it in the computer storage server cluster for archiving for big - data analysis. The application publishing server can also obtain historical calculation data, configuration data, etc. from the computer storage server cluster according to the query needs of the station terminal for the station terminal to use.

[0035] The computing server sends data to the D5000 system through a reserved interface for display in the D5000 system. Taking a photovoltaic power station as an example, through the method of a large table, the operation status information of each photovoltaic array in the photovoltaic power station is presented. It should include: display of installed capacity, number of installed units, grid - connected capacity, number of grid - connected units, number of generating units, generating capacity, number of stopped - generating units, stopped - generating capacity, real - time output, ambient temperature, etc. The measuring points involved include:

[0036] Installed capacity; Number of installed units; Number of power generation units; Power generation capacity; Number of units out of service; Capacity of units out of service; Ambient temperature;

[0037] Installed capacity: Fixed value;

[0038] Number of installed units: Fixed value;

[0039] Number of power generation units: Power generation when power > 0;

[0040] Power generation capacity: Summation of the installed capacities of units with power > 0

[0041] Number of units out of service: Power <= 0

[0042] Capacity of units out of service: Summation of the installed capacities of units with power <= 0

[0043] Unit part:

[0044] According to the power, display its power generation status in color, divided into 5 intervals

[0045] Off-grid (gray), under maintenance (purple), standby (red), full load (orange)

[0046] Output: 0 > -10%; 10% - 30%; 30% - 50%; 50% - 70%; 70% - 100%

[0047] Calculation: Power / Installed capacity * 100%

[0048] Statistics function: For the site part, according to the selected time period, statistically calculate the maximum value of the site parameters within this time period. Click on the specific value to display the trend within the selected time period.

[0049] Furthermore, as Figure 2 shown, the new energy single unit upload server is set outdoors at the site. The new energy single unit upload server includes a computer main body and an outdoor protection box. The outdoor protection box includes a cabinet body 1 and a cabinet door 2. The cabinet door 2 is hinged to the cabinet body 1. A wiring bin 3 surrounded by partitions is arranged at the bottom of the cabinet body 1. The inner cavity of the cabinet body 1 forms a horizontally placed L-shaped air duct structure due to the existence of the wiring bin 3. A ventilation hole 4 communicating with the outside is arranged on the side wall of the wiring bin 3. The bottom of the wiring bin 3 is an open structure for cables to enter. An air vent box 5 communicating with the wiring bin 3 is also arranged at the bottom of the cabinet body 1. A heat dissipation assembly is arranged above the air vent box 5. The heat dissipation assembly is located at one end of the bottom of the horizontally placed L-shaped air duct structure. A slide rail 6 for installing the computer main body is arranged at the upper end of the horizontally placed L-shaped air duct structure. An exhaust hole 7 is arranged above the slide rail 6.

[0050] Set a cement base on-site to place the outdoor protection box, and dig a cable trench under the cement base. The cable trench is used to supply power to the new energy single-unit upload server and provide communication connection cables. To avoid environmental impact, the set outdoor protection box provides a stable working environment for the new energy single-unit upload server. An air duct for cooling is set inside the outdoor protection box to prevent the new energy single-unit upload server from overheating.

[0051] Among them, the heat dissipation assembly extracts air from the wiring compartment 3 through the ventilation box 5. Since the wiring compartment 3 has no bottom cover and is an open structure, some cool air from the cable trench can be extracted, improving the cooling effect. And an aviation plug is set on the top plate of the wiring compartment 3, and a female seat of the aviation plug is set at the end of the cable. This enables the computer main body inside the cabinet 1 to be directly connected inside the cabinet 1 through the cable, improving the sealing performance of the cabinet 1.

[0052] Furthermore, the side wall of the ventilation box 5 is communicated with the wiring compartment 3, and a ventilation port 8 is set above the ventilation box 5. The ventilation port 8 is in butt joint and communication with the air inlet end of the heat dissipation assembly.

[0053] Furthermore, the heat dissipation assembly is set on the cabinet door 2, including an assembly housing 9 and a filter element 10, an air extraction fan 11 and an exhaust pipe 12 set inside the assembly housing 9. The filter element 10 is installed at the bottom of the assembly housing 9 and forms a butt joint and communication with the ventilation box 5 by means of the opening and closing of the cabinet door 2. The slide rail 6 is arranged in a stepped layout that slopes upward from bottom to one side of the cabinet door 2. The edge of the computer main body is located within the vertical projection range of the exhaust pipe 12.

[0054] With the help of the stepped layout of the slide rail 6, the computer main body enters the projection range of the exhaust pipe 12 in a stepped manner. When there are multiple computer main bodies in the device, each layer of computer can receive the air-cooled air flow. And after the air-cooled air flows horizontally through the computer main body, the hot air converges at the stepped structure behind the computer main body. Due to the existence of the same stepped structure, the hot air discharged from the lower computer main body will not interfere with the upper computer main body.

[0055] The ventilation port 8 forms a butt joint seal with the filter element 10 when the cabinet door 2 is closed, enabling the air extraction fan 11 to draw air from the wiring compartment 3 through the filter element 10. A fixing groove 13 in a U-shaped structure is set at the bottom of the assembly housing 9. The side wall of the fixing groove 13 and the assembly housing 9 are inserted and fixed by means of a limit pin 14. A through hole communicated with the ventilation box 5 is set at the bottom of the fixing groove 13. The filter element 10 is clamped at the bottom of the assembly housing 9 by means of the fixing groove 13. When the cabinet door 2 is opened, the filter element 10 is exposed by means of the fixing groove 13, and the filter element 10 can be quickly replaced by unplugging and plugging the limit pin 14, facilitating quick maintenance in the outdoor environment.

[0056] Furthermore, as Figure 3As shown, an exhaust cap 15 is further provided. The exhaust cap 15 and the top of the cabinet body 1 enclose an exhaust cavity 16. The exhaust hole 7 is communicated with the exhaust cavity 16. The bottom edge of the exhaust cap 15 extends out of the outer edge of the top of the cabinet body 1 and is provided with an edge hole 17 communicated with the outside.

[0057] The provided exhaust cap 15 has a roof-like structure. The exhaust hole 7 is communicated with the exhaust cavity 16. The hot air is discharged from the edge hole 17 after being transferred through the exhaust cavity 16. The edge hole 17 is arranged downward to prevent rainwater from invading.
