Embodiment Construction

[0030] see figure 1 , providing an embodiment of a power communication network line optimization method, including the following steps:

[0031] S100: Initialize the lines to be selected of the power communication network lines.

[0032] Power communication network line optimization refers to the selection of better lines for network expansion on the basis of the existing power communication network structure, that is, there may be established lines in the power communication network lines, and the cost of these established lines is no longer the cost of line optimization. cost considerations. When constructing a network, there are many combinations of lines between nodes in the entire power communication network. It is necessary to initialize the optional lines in the power communication network to obtain the lines to be selected. Select a line from Select Line to expand. In order to realize the line optimization problem, the concept of graph is introduced. The nodes in th...

Abstract

The invention relates to a method and a system for optimizing a power communication network circuit. The method comprises the following steps: constructing a cost function of a to-be-selected power communication network circuit planning scheme and calculating a ring formation rate; establishing a fitness function according to the cost function and the ring formation rate; employing a particle swarm optimization to obtain a global optimal position which meets preset constraint conditions and whose fitness is the smallest in all particles; obtaining an optimal solution of circuit selection parameters; and taking the circuit corresponding to the optimal solution as an optimal circuit of the power communication network circuit planning. The preset constraint conditions include the circuit selected correspondingly via a position and the established circuit form a connected graph, the ring formation rate of nodes in the connected graph formed by the circuit selected correspondingly via the position and the established circuit is greater than or equal to a preset threshold value, and the circuit selected correspondingly via the position meets service distribution constraints, so that the circuit selection parameters corresponding to the global optimal position are optimal; and through constructing the circuit selected correspondingly via the optimal circuit selection parameters, while the reliability of the power communication network circuit is improved, the cost is reduced.

Description

technical field [0001] The invention relates to network optimization technology, in particular to a method and system for line optimization of a power communication network. Background technique [0002] Power communication network line optimization refers to determining the most economical communication line deployment scheme on the basis of known node locations and business distribution, according to the existing network structure, and under the conditions of satisfying business distribution and reliability constraints. With the increasing scale of the power grid, the optimization problem of the power communication network line becomes more and more complicated. Therefore, the in-depth research on the optimization of power communication network lines not only plays a positive role in the good operation of my country's power system, but also has a positive effect on social stability and the rapid and healthy development of the national economy. The existing power communica...
