Description

Intelligent control system for inverter aging

Technical Field

The utility model belongs to the technical field of the electric power system technique and specifically relates to an ageing intelligence control system of dc-to-ac converter.

Background

In recent years, with the rapid popularization and development of solar energy, the photovoltaic inverter comes to spring in the industry, the inverter technology gradually matures along with the market demand, the two-year energy storage technology gradually rises, and the light storage hybrid inverter technology is relatively matured and perfected. Before an inverter leaves a factory, the inverter can be packed and leaves the factory after discharge aging is confirmed to be free of problems, the traditional aging process is that a parameter setting work station is arranged before aging to set the mode of the inverter into an aging mode, aging data is uploaded to a server through a network during aging and is judged whether the aging data meets passing standards or not, if the aging data meets the passing standards, the aging is passed, otherwise, the aging is judged to be abnormal, if the inverter does not have a WiFi function, the aging needs to be carried out in a wired mode, and after the aging is passed, the aging mode needs to be erased by the parameter setting work station, so that manpower, material resources and production period of two steps are wasted,

therefore, the prior art has yet to be developed.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned prior art's weak point, the utility model aims at providing an ageing intelligent control system of inverter. The intelligent control system aims to solve the problems that the resource utilization rate is not high and the intelligent degree is not enough in the prior art.

In order to achieve the purpose, the utility model adopts the following technical proposal:

the utility model provides an ageing intelligence control system of dc-to-ac converter, a serial communication port, include:

the system comprises a plurality of inverters, wherein an Internet of things module with a wifi function is arranged in each inverter;

the wireless network generating device is respectively in communication connection with the inverters through transmitting wifi;

the control module is electrically connected with the L AN port of the wireless network generating device;

and the service terminal is in communication connection with the wireless network generation device.

Further, the wireless network generation device comprises a wireless router.

Furthermore, the control module adopts an intelligent aging control module Factory APP developed based on the Windows IoT system.

Furthermore, an exchanger is connected to a WAN port of the wireless network generating device, the wireless network generating device is connected to the Internet through the exchanger, and the service terminal is in communication connection with the Internet.

Further, the internet of things module is developed based on a Windows IoT system.

Further, the control module sends an aging instruction to the inverters through the wireless network generating device every first time interval, so that the inverters start to convert direct current input into alternating current output at rated power, and when the inverters do not receive the aging instruction continuously for a second time interval, the inverters are reset.

Further, the first time interval is 2 minutes, and the second time interval is 10 minutes.

Compared with the prior art, the utility model, include the thing networking systems based on Windows IoT to along with having the wiFi function, realize the ageing control of intelligence of dc-to-ac converter through establishing ageing control network, saved manpower, material resources and production cycle, and convenient the maintenance, reliable and stable.

Detailed Description

The following description of the preferred embodiments of the present invention is provided for the purpose of illustration and description, and is not intended to limit the invention.

Example 1

As shown in fig. 1, the utility model provides an ageing intelligent control system of inverter, include:

the system comprises a plurality of inverters 5, wherein an Internet of things module 5-1 with a wifi function is arranged in each inverter 5;

the wireless network generating device is respectively in communication connection with the inverters 5 through transmitting wifi;

and the service terminal 4 is connected with the wireless network generating device in a communication mode.

Further, the wireless network generation apparatus includes a wireless router 1.

Further, the control module adopts an intelligent aging control module Factory APP 6 developed based on the Windows IoT system.

Furthermore, an exchanger 2 is connected to a WAN port of the wireless network generating device, the wireless network generating device is connected to an Internet network 3 through the exchanger 2, and the service terminal 4 is in communication connection with the Internet network 3.

Further, the internet of things module 5-1 is developed based on a Windows IoT system.

Further, the control module sends an aging instruction to the plurality of inverters 5 through the wireless network generation device every 2 minutes, so that the corresponding plurality of inverters 5 start to convert the direct current input into the alternating current output at the rated power, and when the inverter 5 does not receive the aging instruction for 10 minutes, the inverter 5 is reset.

The utility model discloses the during operation at first establishes wireless network by a switch 2 and a wireless router 1, and wireless router 1's WAN interface is connected with switch 2, and switch 2 is connected with Internet 3 again.

Any L AN interface of the wireless router 1 is connected with the factor APP 6 through a network cable, and provides a 5V2A direct current source to drive the factor APP 6 to work normally.

The network name and the password of the wireless router 1 are set to be the same as those of the wireless network configured in advance in the internet of things module 5-1.

After the power-on, the WiFi module expanded in the Internet of things module 5-1 of the inverter 5 can automatically search for the wireless network with the same name and password according to the preset wireless network name and password, and automatically connect, and at the moment, the whole aging wireless control network is completely established.

The factor APP 6 connected to the wireless router 1 through the L AN interface sends AN aging instruction every two minutes, the inverter 5 which is normally started up receives the aging instruction through the WiFi wireless network and then controls the inverter 5 to enter AN aging mode, the direct current is inverted into alternating current to be output at a rated power, if the aging instruction is not received within 10 minutes, the connection is considered to be overtime, and the inverter 5 is restarted and reconnected.

After the inverter 5 enters the aging mode, real-time aging data is uploaded to the server side through a wireless network, server side software can automatically judge whether aging passes or not according to the retrieved aging data, if the aging data is abnormal, the aging fails, the inverter needs to be repaired, and if the aging data is normal, the inverter passes, and the normal circulation is carried out to the next step.
