Security check method for running way of power communication network

Abstract

The invention discloses a security check method for the running way of a power communication network. The method comprises the following steps: (1) performing basic data verification: inputting basic data related to the running way, and verifying the uniqueness, rationality and integrity of the basic data; (2) performing service security check: analyzing whether an entire service and each section of route through which the service passes meets an N-1 requirement or not on the basis of a communication service route, and judging whether the service is safe or not during service clearing to make a service security check conclusion; (3) performing system security check to make a security check conclusion of a system; and (4) outputting a check result. According to the method, a relevant service circuit basic encoding rule is put forward on the basis of service N-1 analysis and system security check, and analysis of the service security and system security of the power communication network is realized on the basis of the encoding in combination with N-1 service influence analysis and an effective outlet analysis algorithm, so that a reliable and stable running way security check system can be realized by adopting the design, and online and real-time analysis of the running way of the communication network is realized.

Description

technical field [0001] The invention relates to a method for checking and analyzing the safety of the operation mode of an electric power communication network, in particular to a method for checking the safety of the operation mode of the electric power communication based on the N-1 principle and an effective exit algorithm. Background technique [0002] As the basic support for the operation of the power system, the power communication network carries important services such as relay protection and stability control. With the expansion of the scale of the power communication network, the increase of services carried, and the in-depth sharing of network resources at all levels, the detailed composition of the communication circuit must be clearly described. Referring to the concept of power system operation mode, the concept of communication network operation mode is gradually formed, which includes: the composition of communication network, the use of communication resour...

[0007] (2) The above analysis methods do not support the N-1 principle of electric power communication. The N-1 principle of electric power is also called the single fault safety criterion, which is an extremely simple safety inspection criterion. Guiding significance

When the power plant has only one outgoing line, the failure of the outgoing line may result in the loss of more than one generating set,

[0008] (3) In addition, there is no effective exit to the communication site and system to analyze the security of the business and the system, and the degree of impact on the business is not comprehensive enough
