Abstract

The invention discloses a QoS control-oriented UHV grid system protection service path planning method, which belongs to the technical field of electric power information communication. The specific technical solution is: Step 1, definition of system protection service QoS parameters; Step 2, modeling of QoS control-oriented UHV power grid service path planning; Step 3, QoS control planning algorithm based on distinction between main path and backup path. Combining the characteristics of cross-carrying and cross-carrying of the service communication paths of the UHV power grid, the present invention proposes a QoS control-oriented UHV power grid system protection service path planning method. First of all, taking into account the business characteristics to build node and link risks, and further proposed two QoS indicators of network comprehensive risk and similarity; further for the main and backup paths of the business, a risk minimization model was built. Afterwards, according to the model, a QoS control planning algorithm for active and standby paths based on distinction is proposed to realize independent active and standby path planning that meets the requirements of various QoS parameters.

Description

technical field [0001] The present invention relates to the field of electric power information communication, and more specifically, relates to a QoS control-oriented UHV grid system protection service path planning method. Background technique [0002] In recent years, with the development of economy, it has become an inevitable requirement for the development of my country's power grid to establish a low-loss, long-distance, and large-capacity transmission system. In addition to meeting the long-distance and large-scale transmission requirements, the UHV transmission network can also improve the security, economy, and resource allocation capabilities of the power grid. It is the key to building a smart grid and global energy Internet. Due to the construction of the UHV power grid and the gradual expansion of the grid scale, the traditional power system protection strategies and protection methods have gradually failed to meet the needs. In order to achieve effective prote...
