Abstract

The invention discloses a method and a device of transmitting power grid communication data as well as a power grid communication system. The method comprises the following steps that: the power grid communication data is encrypted by a power distribution side; and the encrypted power grid communication data is transmitted to a master station side by the power distribution side. By applying the method of encrypting the power grid communication data, which is disclosed by the invention, interactive data in a data interaction process can be encrypted data, the problems of the risk from attack of a public network due to a low-voltage power distribution network adopting a public network communication manner, and influence on safe and reliable power supply of a user due to execution of a hostile attack command can be solved, so that an illegal worker is prevented from tampering the power grid communication data to influence safe and reliable power supply of the user, reliability of power grid interaction data is improved, and reliability of safety utilization of electric power of the user is improved.

Description

technical field

[0001] The present invention relates to the field of communications, and more specifically, to a method and device for sending grid communication data and a grid communication system. Background technique

[0002] With the rapid development of medium and low voltage distribution networks, due to limited conditions, some medium and low voltage distribution networks that do not have dedicated line optical fiber communication conditions generally adopt public network communication methods, for example, General Packet Radio Service (General Packet Radio Service, referred to as GPRS) / Code Division Multiple Access (CDMA) / Time Division-Synchronous Code Division Multiple Access (Time Division-Synchronous Code Division Multiple Access, TD-SCDMA) / 230MHz etc.) transmission control command, causing the system to face the risk of attacks from the public network, which may affect the safe and reliable power supply to users; at the same time, there is a security threat that...

Embodiment Construction

[0023] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0024] Based on the related technology, the low-voltage distribution network that adopts the public network communication method faces the risk of attack from the public network, and the execution of malicious attack commands will affect the safe and reliable power supply of users. Embodiments of the present invention provide a transmission network A method of communicating data, the flow of the method is as follows figure 1 As shown, including step S102 to step S104:

[0025] Step S102, the power distribution side encrypts the grid communication data;

[0026] Step S104, the power distribution side sends the encrypted grid communication data to the master station side.

[0027] The embodiment of the present invention uses the method of encrypting the communication data of the power grid, so that the data exchanged in the process o...
