摘要
电力通信网犹如电力网络的神经系统,而可靠性对电力通信网又至关重要。针对电力通信网可靠性的重要性,提出了基于效能的可靠性评估方法。首先,建立了电力通信网络的效能模型,实现了对电力通信网网元及网络的效能模拟。然后,依据效能与可靠性之间存在的数学关系,利用所建模型中网络效能的实时变化来间接地反映网络的可靠度变化。仿真结果表明,文中所建效能模型对网络及网元效能具有很好的模拟效果,能够客观地模拟和反映网络效能随时间变化的规律,进而实现了对网络可靠度估的有效评估。
The power telecom network is regarded as the nervous system of the power grid, and the reliability is critical to power telecom network. In the light of importance of reliability, based on the concept of efficiency, a new method for the evaluation of reliability is proposed. Firstly, the efficiency model for power system communication is built, the efficiency of network and net- work units can be simulated. Then, on basis of relationship between efficiency and reliability, the reliability of the network is re- flected whereby the change of network efficiency timely. Simulation results show that the performance of this model is well. The change of efficiency conforms to the actual network, and then the model realized the evaluation to network reliability.
