The operation and management of wind farms must comply with the requirements of the National Energy Administration and the State Grid for the safety of power production networks. The main feature is that the production management network of the wind farm is divided into three safety zones according to the safety level, corresponding to different production control and management functions and different safety level requirements.
Industrial Internet technology wants to play to the advantages of networking, cloud computing and intelligence, it is necessary to complete the data access of production real-time data to the industrial Internet platform.
According to the security zone of the wind farm production and management network, the operation data of the equipment is generated in one zone. According to network security requirements, only the three areas can interact with the outside world through encryption.
Therefore, the real-time production data must be forwarded through a three-zone system that meets the network security requirements to achieve data access from the wind farm to the industrial Internet platform.
Main demand
data collection:
Obtain real-time data of the production operation process from a variety of equipment, the most important of which is the real-time operation data of the wind turbine;
Data forwarding:
The data is forwarded through the first area to the second area, and then from the second area to the third area;
Data cache:
Solve data loss caused by network interruption.
Difficulties and pain points
The data acquisition link, the non-standard protocol of the data system used by the wind turbine, and the measurement point information of the wind turbine control system.
For engineers engaged in software, communications or Internet development, data forwarding, data encryption, and data caching are all things they are good at.
However, in the data acquisition link, very trivial details in the field of wind power will be involved, especially the measurement point information. At the same time, due to the private protocol adopted by the wind power master control system, the documents and public information are not complete, and the private protocol connecting with different master control equipment will also consume a lot of trial and error costs.
Solutions we provide
The dedicated real-time data gateway for wind farms is our solution for this situation. The gateway solves the problem of data acquisition through two aspects of work.
Protocol conversion
Docking the communication protocol of the mainstream wind power main control system, and at the same time converting the data into standard industrial Internet communication protocols, including mainstream communication protocols such as Modbus-TCP and OPC UA.
Standardization of measuring point information
According to the domestic mainstream wind turbine models, combined with the knowledge of the wind power field, complete the point meter configuration of different models.
