Application analysis of trusted WLAN wireless access technology in new power system

The development of highly intelligent power grid and the construction of new power system bring the demand of massive data access. In recent years, with the continuous updating and iteration of communication technology, the power system has formed the ubiquitous communication network which is mainly based on optical transmission technology and supplemented by a variety of wired and wireless access technology. For terminal access communication network, using wired communication can improve communication reliability and security, but optical transmission network deployment will bring huge investment. Trusted WLAN is a wireless coverage extension of the power fiber private network. It adopts the WAPI authentication standard and has higher security than the US-led Wi-Fi security technology. It provides secure and reliable wireless access for power terminals and prevents unauthorized access, forgery, and intrusion. On the other hand, the current trusted WLAN construction scheme needs to be based on the power fiber private network for wireless access coverage. Therefore, the adaptation of this technology to power services needs to be thoroughly analyzed in terms of communication performance indicators, security, and economy.
