Operation method and device for communication equipment in smart substation

Abstract

The present application discloses a method and device for operating a communication device in a smart substation. After receiving an operation ticket application request including an operation time period and a MAC address of the communication device, according to the MAC address, sending the operation time period including the operation time period to the communication device. After receiving the operation ticket information including the hash sequence sent by the communication device, the hash sequence is obtained by the communication device using the hash algorithm for its own MAC address, and the code generated by the operation management device is generated. and the first operation ticket serial number of the hash sequence; send a notification message to the communication device, the notification message includes the operation time period and the first operation ticket serial number, so that the communication device can judge whether or not according to the notification message and the input operation information Execute the operation command in the operation information. It can be seen that this method improves the operation safety of the smart substation by incorporating the communication equipment in the smart substation into the scope of operation ticket management.

Description

technical field [0001] The present application relates to the technical field of communication in smart substations, in particular to an operation method and device for communication equipment in smart substations. Background technique [0002] Smart substations are composed of advanced, reliable, energy-saving, environmentally friendly, and integrated equipment. Based on high-speed network communication platforms for information transmission, they automatically complete basic functions such as information collection, measurement, control, protection, metering, and monitoring. Substations that need to support advanced application functions such as real-time automatic control of the power grid, intelligent regulation, online analysis and decision-making, and collaborative interaction. The operation ticket technology and related management specifications are the main measures used to prevent misoperation (misoperation, misconnection, pull with load, close isolating switch, clo...

Problems solved by technology

[0004] However, the inventor found that the operations of other equipment other than the protection measurement and control device, such as restarting, parameter reconfiguration, etc., also play a vital role in the function of the entire smart substation, but these equipment only log in through login information, and Many applications still use the factory default settings, such as user name: administrator, password: 111111. It can be seen that the above-mentioned devices can operate the corresponding devices only through the login information, which may easily cause security issues such as information leakage or network attacks.
