Embodiment (1): Referring to Figure 1 and Figure 3, the information security exchange strategy in the network system for exchanging power information is described, including:

(1) Border security protection strategy:

Under the premise of strictly following the security protection standards, in order to enhance the security and stability of business access, and build adaptive and efficient links, the efficiency of information exchange has been improved several times (as shown in Figure 3, see the following examples for details ( two)).

(2) Stability protection strategy;

A network system for exchanging power information includes a plurality of communication channels for transferring power information. For each communication channel, referring to Figure 1, the network system for exchanging power information is used to:

101. When the data volume of the power information to be transmitted in the communication channel is greater than the preset data volume, determine that the power information to be transmitted is power information with a super large data volume, wherein the data volume may be the size of a data file;

102. Compressing the power information with a large amount of data in volumes to obtain multiple compressed files in volumes, wherein, compression in volumes refers to dividing the power information with a large amount of data into multiple volumes, and compressing each volume separately;

103. Using a step-by-step communication method, each sub-volume compressed file in the multiple sub-volume compressed files is sequentially transmitted through the communication channel.

That is to say, a stability protection strategy is implemented. In order to avoid the occupation of communication channel resources during the exchange of large data, resulting in network freezes and service resource congestion, which in turn leads to poor channel stability, data volumes are adopted for communication of large resources. Compression and step-by-step communication methods ensure the stability of data collection and exchange.

Obtain the historical time consumption of historical transmission links in the network system for exchanging power information, and the time consumption refers to the time consumption of long connection requests for transmission links;

The sum of the historical time-consuming length and the preset time-consuming offset is used as the time-consuming threshold;

It is detected that the time consumption of the current transmission link exceeds the time consumption threshold, and the current transmission link is disconnected.

That is to say, a fault-tolerant optimization strategy for information exchange is implemented. Through the analysis of historical samples of transmission links, the link duration of various access devices is calculated regularly, and solidified in the configuration. The duration plus a certain offset is used as the threshold. Automatic disconnection after the threshold, which solves the problem of automatic recycling of abnormally long connections in the system, making the overall network operation more stable.

According to the network structure dedicated to the private network in Figure 2, it is difficult to meet various Structural changes of various power sources, grids and loads. Therefore, it is necessary to use the "wide area network + intranet mode" to complete the information interaction between the internal and external networks through the network system for exchanging power information, and break the barriers that exist in the information collection and interaction of the private network in traditional scheduling production management.

The power information exchange service provided by the proxy server is web service. The web service uses https protocol for encrypted communication and identity authentication. The power information in the proxy server is deleted immediately after the information transmission is completed. It can be understood that the power information in the proxy server is temporary data, which can be deleted after completing the transmission link to ensure the release of channel resources.
