[0114] Step 1: Calculate business weight

[0115] According to relevant surveys and expert experience, the importance of business is mainly determined by the type of business and the level of business scheduling, and the contribution of the two to the importance of business is 0.7 and 0.3 respectively.

[0116] Give business types respectively {power distribution automation, scheduling automation, relay protection, network management business, fully automatic device, dispatching telephone, administrative telephone, integrated data network, dispatching data, video conference call, protection PCM, communication PCM, video service, frequency control business} and service scheduling level {level 1 network, level 2 network, level 3 network, level 4 network, level 5 network}, the scoring interval is [1,10], and the score is given by relevant experts.

[0117] w=0.7×w T +0.3×w D

[0118] Among them, w T Score for business type, w D Scoring the business scheduling level, w T ∈[1...

Abstract

The invention belongs to a network optimization problem, relates to the optimization of a business routing distribution scheme in a power communication network, and especially relates to a communication network optimization method based on a hierarchical analysis method and a genetic algorithm. According to the invention, the method employs the hierarchical analysis method from the angle of the general risk degree of a power communication network and the node and business risk balance degree, combines the qualitative and quantitative methods, enables a complex decision-making system to be hierarchical, provides the quantitative analysis for the analysis and decision making through the level-by-level comparison of various kinds of correlated factors, and proposes a standard for the judgment of the quality of a communication network. The standard is taken as an objective, and the method employs the improved genetic algorithm, and proposes a new coding mode and variation mode, thereby solving a problem that the binary coding of a conventional genetic algorithm is not sufficient in expression of the problem, and achieving the optimization of the communication network.

Description

technical field [0001] The invention belongs to the problem of network optimization, and in particular relates to the optimization of service routing distribution scheme in electric power communication network. Background technique [0002] The power communication network is the infrastructure of intelligent and automatic power production. As an important means to ensure the safety, stability and economic operation of the power grid, the power communication network occupies a pivotal position in the power system. [0003] At the same time, the power communication network is the infrastructure that carries the interactive information between power systems. Once a security incident occurs in the power communication network, it will first directly affect the service quality of the power communication system, and secondly, it may pose a threat to the safe and stable operation of the power grid. In recent years, with the increasing scale of the power system, although the maintena...
