Embodiment Construction

[0035] The specific embodiment of the present invention is as figure 1 shown.

[0036] The present invention comprises the following steps:

[0037] The first step is to collect the relevant attribute values ​​of each communication mode in the standardized smart grid, and consider the difference between cost-type attributes and standard-type attributes, and establish a multi-attribute matrix of communication modes. The attribute values ​​obtained through measurement and accounting are expressed in the form of matrix.

[0038]

[0039] In the formula, the abscissa represents the attribute, and 1-7 represent the reliability P 1 (percentage), transmission bandwidth P 2 (Mbit / s), the cost price P of communication nodes 3 (thousand yuan), bit error rate P 4 (percentage), ease of maintenance P 5 (score), the influence of the external environment P 6 (Score), the impact of power lines P 7 (Fraction). The vertical axis indicates the communication mode, which respectively i...

Abstract

The invention discloses a multi-attribute communication mode selection algorithm for an automation terminal in a distribution communication network, and the algorithm comprises the following steps: (1) collecting and calculating the attribute data of all communication modes; (2) building a multi-attribute matrix of the communication modes, and employing a range transformation method to convert the multi-attribute matrix into a standardized decision matrix; (3) building a decision matrix for communication mode selection; (4) calculating a comprehensive weight vector according to a subjective weight vector and an objective weight vector, wherein the subjective weight vector is obtained through an AHP method, and the objective weight vector is obtained through an entropy evaluation method; (5) calculating the performance estimation values of all communication modes, where the communication mode with the maximum performance estimation value is the optimal communication mode. The algorithm gives consideration to the impact on the communication modes from multi-attribute combination, also gives consideration to the subjective interests of a user and the objective difference among all the communication modes, and enables the appropriateness degrees of communication modes of automation nodes in an intelligent power grid to be sorted, so as to select the optimal communication mode as the communication mode of the automation nodes.

Description

technical field [0001] The invention relates to a multi-attribute communication mode selection algorithm for an automation terminal in a power distribution communication network, belonging to the technical field of smart grid communication. Background technique [0002] Communication technology plays a pivotal role in the smart grid, and an effective and reliable communication system is the premise and foundation for the realization of smart grid services. The planning of the communication network directly affects the effective operation of the smart grid. Faced with the high quality of service (QoS) and low-cost diversified service requirements of future smart grid communications, a single network communication method can no longer meet the business growth needs of future smart grid customization, and any communication method is not enough to construct alone Power communication network. With the continuous development of power communication technology, according to the di...
