The present invention discloses an automatic
access method for a self-describing plug-and-play power distribution terminal. The method comprises a standard configuration process, an automatic login and security
verification process and a power distribution terminal CID (Configured IED (
Intelligent Electronic Device) Description) file acquisition process. For the standard configuration process, an IEC61850 configuration technology is applied, an CID file is instantiated, and a security
certificate file is downloaded; for the automatic login and security
verification process, the CID file is read and a login message is generated, and a login process is automatically initiated after power-on, and an automatic login to a power distribution
master station is completed, wherein, the power distribution
master station performs security
verification on a power distribution terminal by checking a
certificate, updating the
certificate and checking a signature; and for the power distribution CID file acquisition process, a CRC32 checking code is compared, the CID file of the power distribution terminal is updated according to needs, so as to implement automatic access of the power distribution terminal. The present invention provides the automatic
access method for the self-describing plug-and-play power distribution terminal, which enables the power distribution terminal to automatically and rapidly access a power distribution network, so that operation and maintenance costs are reduced.
