Technical Field

Background
With the continuous advance of smart grid construction, the requirement on the automation level of operation and management of an electric power system is continuously increased, and a large amount of information related to power production, operation and management needs to be safely, reliably, stably and rapidly transmitted through an electric power communication network. The communication transmission network is the central nerve of the power system and is an important foundation for ensuring the safe, stable and reliable operation of the power system. A Synchronous Digital Hierarchy (SDH) transmission network is widely used in a power communication backbone network as a new system that combines a high-speed high-capacity optical fiber transmission technology and an intelligent network technology. In order to ensure the network performance of the SDH transmission network when carrying various services of the power system, related network performance analysis, test, and reliability evaluation must be performed in the processes of SDH network construction, activation, operation, and maintenance. Under the existing experimental facilities and technical conditions, for a small-scale SDH network, an experimental platform can be set up by utilizing SDH equipment, a network analyzer, an SDH analyzer and other instrument equipment to analyze and evaluate the network performance. However, for a large-scale SDH transmission network, for example, a multi-level wide area SDH communication transmission network including province-province, province-city, city-city, etc., is limited by factors such as experimental facilities, technical conditions, and test cost, and it is difficult to simulate and test the performance of such a network by building a test platform. At present, how to analyze and evaluate the performance of the large-scale power system SDH communication transmission network still remains to be solved.
In view of the difficulty in constructing a test system of a large-scale power system SDH transmission network in an experimental environment, a feasible method for researching and analyzing a large-scale power system SDH communication transmission network is to perform network modeling simulation by using a computer. However, the existing network software simulation tool only performs modeling simulation on a general network, and cannot be directly applied to power system SDH communication transmission network simulation modeling.
