The Design And Implementation Of Accident Impact Analysis Simulation In SDH Network Of Power Grid

In China, with the constant improvement of the power grid construction, a multi-level interconnected fiber SDH power communication network has been built for the transmission of the power grid business information. Meanwhile, with the construction of smart grid, SDH communication network of the power grid is increasingly obviously. While reliability requirements of SDH network increasing, SDH network has become more complex and difficult to maintain and the network equipment and network operation and management mode become more diverse than before. All of those situations make the network planning and optimization complexity and the SDH network operation and maintenance requires high level specialist. Simulation technology of communication network provides reliable basis for the equipment development, network planning, network optimization analysis, planning and design and reduces the cost. It also can provide an environment for the training and anti-accident maneuver to improve the ability of operation and maintenance. And the accident impact analysis simulation as an important part of Simulation technology of communication network is significant in the SDH network applications and research。This thesis presents an accident impact analysis model and implements the corresponding simulation module. Simulation module simulates the SDH network accident by the simulation of resource, action and inspiration. Resource simulation simulates the resource of SDH network at device level, network level and business level. Action simulation simulates the state change of the resource object when it accepts inspiration and the inspirations the resource object can dispatch when it state changes.At first, this thesis introduces the background and related technologies of this area.Then according to the process of software development, it completes the needs analysis, outline design, detailed design, and implementation of the simulation module. At last, it discusses the further development of simulation technology of commucation network.
