Abstract

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.

Description

Technical field

[0001] The invention relates to the field of electric power systems, in particular to a method for automatic access of a self-description plug-and-play power distribution terminal. Background technique

[0002] With the continuous development of the economic level, distribution automation has entered a period of high-speed construction in China. At present, as the public's dependence on the power grid becomes higher and higher, the requirements for the reliability of the power grid for safe operation, production and life in cities are also getting higher and higher. The corresponding distribution terminals of the distribution automation monitoring and execution equipment are widely distributed, Large numbers, harsh operating environment, difficult operation and maintenance, and high risk of failure. In actual applications, power distribution terminals produced by different manufacturers cannot be interchanged, and information cannot be interconnected. Complex conf...
