Abstract

The invention discloses an access authentication method of a distribution network automated communication device based on an ID, belonging to the field of distribution network automated communication systems. The method comprises the following steps that: a distribution automated control center, a regional workstation, a distribution terminal unit and a distribution automated communication network in a centralized control mode are established; and a key management server of the distribution automated control center conducts the key allocation, and the regional workstation and the distribution terminal unit compare whether deciphered data are the same to realize the access authentication, thereby realizing the function that any device can be installed in the distribution network automated communication system only by acquiring the key issued by the key management server. The invention is applicable to the large-scale distribution network, simplifies the key management, utilizes the communication and calculation processing capacities of the regional workstation, and solves the problems of the limited calculation and communication capabilities of the distribution terminal unit. Besides, the invention realizes the mutual authentication of the devices, thereby increasing the safety, improving the access safety of the distribution network device and improving the access safety of distribution network device.

Description

technical field [0001] The invention relates to the field of distribution network automation, in particular to a device access authentication method of a distribution network automation communication system. technical background [0002] In recent years, the rapid development of computer technology, information processing technology and communication technology has had a huge impact on the power system: on the one hand, openness, interconnection and standardization have become a development trend of information systems in the power industry, on the other hand , various new concepts such as digital power system and smart grid have been proposed continuously, and have become the focus of attention in the application technology of transmission and distribution network. In the power system in the digital age, the power grid carries electric energy flow and information flow, information flow guides electric energy flow, and electric energy flow depends on information flow. The s...
